http://ask.metafilter.com/233292/Data%2DDriven%2DClinical%2DCare%2DDynamic%2DGraphing%2DWebsite
I would like advice on creating a dynamic graphing website to display clinical data on a intranet website to better aide clinicians. What my superiors are seeking is a "Data Mall." My programming/server-admin. experience is minimal, but my Linux-hobbyist mentality <i> hates </i> the MS Access solution that is being built. <u>The scene:</u><br>
<br>
So, our administrators have fallen in love with a concept that they have seen at a conference where clinicians could quickly and easily see a short list of their patients who have certain 'abnormal' clinical values/conditions, or to rank themselves amongst other providers according to certain metrics. Etc. Some call it a "Data Mall."<br>
<br>
Our senior data coordinator has done a great job of leveraging an MS Access database (pulled from our true clinical database) with a VB front-end to be accessed by all providers. But, it still kind of sucks. It takes a long time to load, and is just unwieldy to ask clinicians to use the Access front-end.<br>
<br>
<u>Me, and where I have gotten so far:</u><br>
<br>
I have previously setup my own LAMP CentOS server running MediaWiki just for fun, and was basically able to create a similar setup on a Windows PC using "EasyPHP", on top of which I installed Mediawiki and found a script for making calls to "<strong>Ploticus</strong>" from Mediawiki. I was able to display the simplest-of-simplest pie-charts on my wiki.<br>
<br>
<u>The heart of the matter:</u><br>
<br>
The problem is that this solution seems complex, especially since my PHP and SQL knowledge is limited. Would the best solution just to be to dig in and master this option? Any recommendations for starting points?<br>
<br>
Or is there another tool, method, etc. that I should be looking at?<br>
<br>
I realize that building this could almost be a full-time job, but like I said, part of me is just intrigued by the challenge, and part of me wants to impress the higher-ups. Still, maybe it is best left to the pros...?tag:ask.metafilter.com,2013:site.233292Wed, 16 Jan 2013 13:56:00 -0800rosswaldHave my graph and graph it too?
http://ask.metafilter.com/215379/Have%2Dmy%2Dgraph%2Dand%2Dgraph%2Dit%2Dtoo
How can I generate a graph server-side, and update it client-side? My boss just handed me the job of creating graphs for one of our systems, but he'd like it to work with or without Javascript, so I can't just use one of the many javascript-based graphing libraries unless I also implement the graphs as static images. Flash is also out, since it won't work on the iPad.<br>
<br>
So, what I'm looking for is some way to generate a graph on the server (possibly as SVG?) and then some way to manipulate the graph with Javascript (the dataset gets updated about once every 5 seconds) so that users with Javascript enabled can see auto-updating graphs in the UI (and users with Javascript disabled will just see a static representation of the data as of when the page is loaded).<br>
<br>
Does this kind of thing exist? Or would I just be better implementing things twice?tag:ask.metafilter.com,2012:site.215379Tue, 15 May 2012 08:55:03 -0800fvox13Options for labelling an axis when graphing with Excel
http://ask.metafilter.com/213989/Options%2Dfor%2Dlabelling%2Dan%2Daxis%2Dwhen%2Dgraphing%2Dwith%2DExcel
Excel graphing question: Is there a way to change the axis labels to something you are not graphing? I have some results of a survey which are numerical - but they are the numerical responses to a question like "How much do you like this?" where 1= Not at all, 2=Somewhat, 3=I love it!<br>
<br>
So I'm graphing the average of the responses which are obviously numerical: the mean of Group A's average is 1.35, while the mean of Group B's is 2.46. And currently, the Y-Axis of my graph is labelled numerically (1, 2, 3, etc), as that is the range of values from which I have generated the graph.<br>
<br>
However, I am graphing this for a research participant newsletter, and I would like to change the Y-axis labels from being the numbers (which have no meaning) to saying "Not at all", "Somewhat" and "I love it!"<br>
<br>
Is this possible within Excel? (My other option is just to suppress the labels and add a textbox after I import the graph into Word, but that's bothersome). <br>
<br>
(Yes, I know that there are better programs for graphing - our data analyst uses one. But I have to publish the newsletter using word, and it's easier to lay out colours, fonts, etc with Excel than to be using an image generated from another program).tag:ask.metafilter.com,2012:site.213989Fri, 27 Apr 2012 12:25:10 -0800jbFree online graphing app that plays well with Excel?

Asking for a colleague:
"Back in October 2008, I found a free online app that uploaded data from Excel and produced (very pretty) charts and graphs. Unfortunately, I didn’t keep track of the website, and I’m having trouble tracking it down again. Most of the free graphing apps I’ve found online today require that you manually input the data; I’m looking for something that will more easily upload a set of data from Excel."tag:ask.metafilter.com,2011:site.201623Tue, 22 Nov 2011 14:23:04 -0800lassieDusting Off the Ol' Slide Rule

What are the best math instructional sites, resources and (especially) tools for graphing and math visualization these days? It's been over 20 years since my mathematical high-water-mark (college calculus), but I'm trying to get the ol' brain back in shape. I'm working my way through algebra, geometry, and trig once more, with the goal of eventually getting through calculus in a classroom again. Also, I'm a homeschool parent and my kids aren't that far behind, so this question might help me teach them, too.<br>
<br>
Back in the day, we had non-graphing calculators and had to do all of our visualization on graph paper or mentally. Outside of class time, our resources were limited to the textbook and the teacher's office hours. I hear a lot's changed -- something about "computers" and an "information superhighway"? What are some good online & software tools for helping me get it as I pursue these goals?<br>
<br>
I love Vi Hart, but she's more dessert than main course. I've dipped my toe into the waters of Khan Academy and found it helpful, but it seems to lack the organizational layer a textbook would have. I've heard of Wolfram Alpha but don't really know where to start. Tips on getting the most out of these resources are welcome, as are any stuff I haven't heard of. Free preferred, but excellent paid resources welcome too.<br>

http://ask.metafilter.com/159267/Help%2Dwith%2DCacti%2Dneeded
Question about graphing bandwidth with Cacti using a gauge instead of a counter. (Or, suggestions on other snmp graphing tools) I'm trying to graph an efm group on an adtran router, which instead of using the typical ifinoctet counter, uses something called Curr15MinRxOctets which is a gauge of the last 15 minutes instead of an incrementing counter.<br>
<br>
I've been having a variety of problems getting Cacti to graph this -- starting with the fact that it hangs discovering the thousands of interfaces on the device, and then the only way I can get it to graph that oid at all is by manually creating a datasource for every single interface, which is really unworkable since i have hundreds of these on this router. Also, even with the manually generated graph, the numbers don't seem right at all -- they keep resetting in 15 minute intervals so I think it's not handling the gauge data correctly.<br>
<br>
I'm about to give up on using Cacti to do this -- are there other free tools out there that will discover interfaces using any arbitrary oid and graph them? <br>
<br>
Is there a book on Cacti out there? The documentation is pretty sparse.tag:ask.metafilter.com,2010:site.159267Mon, 12 Jul 2010 11:30:00 -0800empathJust a bunch of points in time

[Geek Filter] I'm trying to figure out a way to take a MIDI file and use the pitch/duration information as data points to create a graph. The animation part isn't as important...I can figure it out once I have the first part taken care of (though if you have ideas, definitely let me know). So, data people - how can I take pitch and duration information from a MIDI file and turn them into graph points? <br>
<br>
I have access to MATLAB, OmniGraffle Pro, Excel, Digital Performer, Sibelius (which I'm using to create the MIDI files from a score I've created), and Reason, but if there's any other software that would make this easy to do, I'm open to getting it.<br>

graphing implicit/3d/whatever (multiple plots) in maple/other software how would I graph this? I'm getting killed by the boundaries on these triple integrals and trying to visualize these graphs without a calculator or any sort of help. for example, how would you get the boundaries from this problem with a graphing software such as maple?<br>
<br>
:::Problem::::<br>
<br>
evaluate the triple integral where E is bounded by the cylinder y^2 + z^2 = 16, and the planes x = 0, y = (4/3) x , and z = 0.<br>
<br>
<br>
I see graphs like this for the problem above that look like my first attachment. The closest I've come is entering it in maple like I've shown in my 2nd attachment for this problem, but why doesn't my graph look like the random professors graph from attachment #1? Mine doesn't have any curves or contours, it's just rigid useless lines. What is their secret?<br>
<br>
I take back the maple only request but if you guys know ANY software where I can successfully enter problems like the above in to visualize them would greatly help me out. In a way I'm looking at larger picture because I want to know how to graph any set of equations, planes, functions in one graph regardless of if there's a x, y, z etc, but this problem would certainly help in getting there.<br>

http://ask.metafilter.com/134102/Quality%2DCommand%2DLine%2DGraphing
Open source, command line, low "impact", png-producing, full-featured, good-looking graphing on Linux and other Unices? We are using a script (Tcl, if it matters) to generate a script that will be sent in an email. Right now, we are using gnuplot. It's been a source of problems. No one particular thing, we just often have "issues" generating our graphs, many of them attributable to gnuplot weirdness. I'd like to rewrite it more robustly and eliminate gnuplot (on a three-strikes basis).<br>
<br>
The "open source" and "command line" are pretty self explanatory. BTW, I don't really consider gnuplot to be command line, because it has its own shell. Yes, you can script it, but I'm looking for something that will take everything (except the actual data) as command line options. <br>
<br>
"Low impact" means "not a lot of extra libs required" and is on the list because we have to manage, build and ship this stuff. <br>
<br>
"full-featured" means that something that just draws a squiggle isn't enough. The particular graph we are sending out is actually a multiplot, i.e. two graphs in the same image file. We need to be able to label axes, change colors, set ranges, etc.<br>
<br>
"png-producing" I think is non-negotiable. Personally, I would be happy to switch image formats (or better yet, go with SVG), but this email has to meet certain other requirements and I dasn't mess with the format.<br>
<br>
"Other Unices" include Solaris and Irix. It doesn't have to ship with those OSes, though, as long as it will compile there painlessly.<br>
<br>
As for "good-looking": <a href="http://www.gnu.org/software/plotutils/">Plotutils</a> is actually perfect, except for one problem: The font rendering (actually, rasterizing) is complete ass. As in nearly unreadable even at reasonable sizes. I actually confirmed this with the maintainer that there is no way to make them look better at the present time.tag:ask.metafilter.com,2009:site.134102Tue, 29 Sep 2009 06:41:19 -0800DUIs there a simple computer program I can use to graph functions?

Is there an easy-to-use computer program (other than TI Interactive) I can use to draw graphs of functions when I'm writing my Algebra 2 tests? Ideally, I'd like to be able to easily graph functions (single functions as well as piecewise functions), save the graphs, and insert them into a Word document. I'm using Windows Vista.<br>
<br>
I loved TI Interactive but for reasons I'm not entirely clear about my school did not renew our subscription to that program this year (I don't know if there is a compatibility issue with Vista or if there is some other reason they did not renew, but the bottom line is I can't use that program any more). I'd like to find something similar to TI Interactive, preferably something that is free or very cheap.tag:ask.metafilter.com,2009:site.132931Tue, 15 Sep 2009 13:44:33 -0800juniperoBest way to do graphs in LaTex?

http://ask.metafilter.com/119110/R%2Dyou%2Dexperienced%2Dwith%2Dplot%2Dand%2Dbarplot
How do I graph these data using R's plot() and barplot() commands? I have data that I need to graph using R. Unfortunately, the examples I have found in books and on the web are too simplistic and do not give me much insight into the process. I have never used R before, and have been trying for hours and hours to figure out how to do what I need to do. I also already read the previous posts about R here on Ask MeFi, but I am still stumped.<br>
<br>
I've made a fake set of data that represents the structure of my real data (which you don't want to see, it's too confusing).<br>
<br>
<a href="http://bengarland.com/r/sample_data.txt">Here is my sample data.</a><br>
<br>
Take a quick look at that. <br>
<br>
There is a main factor/category, Factor1 with values of "BOB" and "JILL", and a grouping within that called SubFactor with values "Q" and "P". I also have blocked reps of everything, labeled A, B, C, D. My measurements are Measurement1, Measurement2, Measurement3, etc which I will abbreviate as M1, M2, M3, etc.<br>
<br>
To cut to the chase, I made a few hand drawings of the graphs I need. Please note that the graphs are illustrative only, and do not correspond to the data above.<br>
<br>
<strong>Please walk me through this step-by-step and assume I know absolutely nothing about how to get my data into R, how to manipulate it as needed, and finally, how to produce the following graphs.</strong><br>
<br>
<strong>ALSO</strong> if any of you R graphing experts want to take me under your wing and help me learn more than I have outlined here (surely I will have future questions), please send me a MeMail.<br>
<br>
----------<br>
<br>
GRAPH 1...<br>
<br>
In the first, I want to make a bar graph of just <em>the average</em> of the M1 measurements for each treatment, split into categories "BOB" and "JILL" with the grouped "P" and "Q" subfactors.<br>
<br>
So that we're on the same page here, the mean of BOB(Q) for M1 = (100+500+200+300)/4 = 275, for example.<br>
<br>
Here is my drawing for this: <a href="http://bengarland.com/r/graph_sample3.jpg">Bar Graph 1</a><br>
<br>
----------<br>
<br>
GRAPH 2...<br>
<br>
In the second, I want a plot of the measurements for "BOB", with M1, M2, M3, M4, and M5 on the X-axis. The lines will represent the "P" and "Q" subfactors.<br>
<br>
Here is my drawing for this: <a href="http://bengarland.com/r/graph_sample1.jpg">Plot 1</a><br>

----------<br>
<br>
GRAPH 3...<br>
<br>
In another bar graph, I want to have M1, M2, M3, M4, M5 be the bars, and have them grouped by BOB (Q, P) and JILL (Q, P) on the x-axis. The Y-axis would show the means.<br>
<br>
Here is my drawing for this: <a href="http://bengarland.com/r/graph_sample2.jpg">Bar Graph 2</a><br>
<br>
----------<br>
<br>
GRAPH 4...<br>
<br>
In the final plot, I want to graph only the mean measurements for "BOB" sub-level "P" <em>over time</em>. Let's say that each M1, M2, M3, M4, M5 was taken at unique times T1, T2, T3, T4, T5 where the times could have values T1=15, T2=45, T3=55, T4=65, T5=70 and they need to be spaced properly on a timeline (i.e. the distance between T1 and T2 should be 30 units, T2 and T3 10 units, T3 and T4 10 units, T4 and T5 5 units) -- <em>I spaced them evenly on the graph, so ignore that.</em><br>

http://ask.metafilter.com/116321/Recommendations%2Dfor%2Dmaking%2DVenn%2Ddiagrams
Does anyone have software recommendations for making Venn diagrams? Especially complicated ones? Hi all, I have a set of data that I want to make a <a href="http://en.wikipedia.org/wiki/Venn_diagram">Venn diagram </a>for, and I was hoping that you might have software recommendations for doing so. <br>
<br>
My data is complicated and has several variables. (It shows how the agricultural sector of the American economy breaks down into grains, fibers, vegetables, etc. as well as where these products end up, such as bread products, pasta, etc.) I am not sure if I will make one big diagram with many circles (perhaps 20) or several smaller diagrams. <br>
<br>
Ideally I will need something that can:<br>
<br>
* Make the circles different sizes to indicate quantity. <br>
* Control the colors of circles. <br>
* Show different degrees of overlapping circles. <br>
* Include many circles -- not just 3. <br>
* Add labels.<br>
* Produces attractive output that is potentially publishable.<br>

http://ask.metafilter.com/109580/Best%2D3d%2Dgraphing%2Dapp%2Dfor%2Da%2Dcheapskate
Best application for 3D graphing (heat maps, contours, bump maps and so on)? I have some data, mostly 3D and the data in higher dimensions can generally be reduced to 3D for analysis. <br>
<br>
A typical dataset has a value for several hundred (x,y,z) triples where I want to map z as a function of x and y, in a heat map, bump map, or contour form. The actual form doesn't matter... it just needs to be easily readable.<br>
<br>
To take a specific example, I could have x = 1, 2, 3 ... 39, 40 and y = 10, 20, 30 ... 490, 500, with z varying between -500 and +500. I'd like to view this data as an (x, y) grid with the z values represented as heights, or colors, or something else.<br>

Excel/Graphing - Time vs. usage (y/n) graph Oh great mefites. How do I create a graph that has on the X axis discrete items, such as "LIGHT A, LIGHT B, LIGHT C", and on the Y axis a timescale.<br>
<br>
Basically I would like to be able to visually share usage patterns of various devices that are either being used, or not used. <br>
<br>
The result would look something like <a href="http://flickr.com/photos/sirstan/2797481388/">this</a>.<br>
<br>
This would be relevant for many Y/N items, such as "what do the usage patterns of my 40 workstations at my business look like", or "what lights are on", or "what ports are on/off on my switch during the day".<br>

I'd like to output a visual map that can be cosmetically tweaked (font, colours and group positioning) and exported as a jpeg or similar to be pasted into a larger report. <br>
<br>
Obviously I've done enough research to know what sorts of academic pages / industry resources about these sorts of tools are available, but I'd like to get it right first try as I don't have much time for trial and error with this project. So, really I'm looking for recommendations issued on an informed basis (first-hand use or similar). <br>
<br>

http://ask.metafilter.com/71440/We%2DDont%2DNeed%2DNo%2DStinking%2DDerivatives
Obscure Mathfilter: In the arcane past of mathematics, there is something known as a "Newton Polygon", which theoretically can be used to help sketch functions of two variables, say, x^3 + y^3 =3xy, for instance. But -- exactly HOW you use the polygon information to help sketch the graph has never been clearly explained to me. <br>
Does anyone know how to do this?<br>
<br>
Related -- there was a post last May or June in (i think) one of the Math Blogs that may have related to this. It was a shortcut approach to sketching polynomials without using derivatives, that just looked at the exponents of each term of the polynomial, and then connected them together using some rules. At the time, I thought "I'll come back and look at this in detail when I get a chance", but, alas, I cannot find it again. (My google-fu is not strong.) Does anyone know what I am talking about?<br>
<br>
Alternatively, how would you sketch f(x, y) by hand, especially if it cannot be explicilty solved for x or y? (I realize all sorts of programs will do this for you; I am interested in by hand techniques.)tag:ask.metafilter.com,2007:site.71440Thu, 13 Sep 2007 05:53:53 -0800wittgensteinIn search of free online tool for creating radial graphs!
http://ask.metafilter.com/67966/In%2Dsearch%2Dof%2Dfree%2Donline%2Dtool%2Dfor%2Dcreating%2Dradial%2Dgraphs
Are there any free online tools for generating <a href="http://en.wikipedia.org/wiki/Radar_chart">radar</a> (aka radial, spider, star) graphs/charts? The ideal tool would be easy to use dynamically and/or against large sets of data to generate multiple graphs.<br>
<br>
I know that Google Documents, for example, provides a lot of graph/chart options, but not this specific sort. On the other end, I'm solid with perl and aware of e.g. <a href="http://search.cpan.org/dist/Imager-Chart-Radial/Radial.pm">radial.pm</a>, but I'd love to find a slick, existing start-to-finish tool rather than having to roll some or all of it myself.<br>
<br>
Any ideas?tag:ask.metafilter.com,2007:site.67966Fri, 27 Jul 2007 15:47:20 -0800cortexHelp me make the graph my boss imagined!
http://ask.metafilter.com/66218/Help%2Dme%2Dmake%2Dthe%2Dgraph%2Dmy%2Dboss%2Dimagined
Graphing question: My boss has an idea of how our data should be presented. Please help me figure out how to make it happen! We have three biological categories, each with several patients. We'd like to show that the different categories have different ages of onset of disease.<br>
I've drawn an <a href=http://www.flickr.com/photos/the_girl/716451717/>example</a> of what my boss would like the graph to look like. <br>
Basically, the three categories are along the y-axis. The month of onset is along the x-axis. The data points for each category at a particular month are spread out to show the number of points at that intersection (the points could be spread in a cloud instead of a line)<br>
Please help!tag:ask.metafilter.com,2007:site.66218Wed, 04 Jul 2007 09:37:21 -0800nprigoda
