http://ask.metafilter.com/264641/How%2Dto%2Dget%2DExcel%2Dto%2Dplay%2Dnice
I am trying to generate an excel graph that will give me a date/time overview, and I can't quite crack how to set up my table and chart :( Any help will be greatly appreciated. I am trying to get an overview of a trend within our IT network, or even to see whether or not any trend exists. I have 6 servers, and every once in a while *something* happens. We keep logs of date&time that this did happen, but because of the MASSIVE input of data (multiple gigs per hour) we do not keep verbose logs. I am trying to plan for a short window when we do turn on verbose logging, so i'd like to see if there is a trend in when the event happens.<br>
<br>
So, how to generate a graph that will show a trend of 6 servers when you have date & time? Do you map this out for each server at a time and then try to overlay? what should my axis be? which chart would be the correct one to use?<br>
<br>
Ideally I could look at this/these graph(s) and say "hmmm, OK, there's a good likelihood that if we have verbose logging from 8-9am we can catch this pesky bug".<br>
<br>
Thank you in advance for any help and suggestions :)tag:ask.metafilter.com,2014:site.264641Fri, 04 Jul 2014 06:33:49 -0800alchemistPaging Mr. Edward Tufte!

I've been doing research involving the treatment of musicians under repressive regimes. A while back I found a graph that had a list of countries, and for each country listed the number of musicians killed, tortured, abducted, assaulted etc. in a certain period of time. But I've lost this graph!! Can you help me relocate it? A few more details....<br>
<br>
- I'm 95% sure that it was musicians who were the subject of this graph (rather than protesters or members of another group).<br>
- the countries represented were ones like Turkey, Iran, Pakistan, Afghanistan, etc.<br>
- it was a chart with country names on one axis and violent actions taken against musicians on the other (eg. killed, tortured, abducted, assaulted, threatened etc.) and numbers at the intersections<br>
<br>
That's all I can remember. My Googling skills have failed me! Any help is appreciated!<br>

(Full disclosure, I'm an undergraduate student doing research on the censorship of music in contemporary Iran.

http://ask.metafilter.com/245294/Blog%2DInfo%2DDisplay%2DWhy%2Dyou%2DSo%2DDifficult
What's the best place to be able to make editable charts for a wordpress.com blog? I'm running a blog that keeps track of people's points in a competitive environment. Link's in the profile if you want to see it, but I don't feel like it's important enough to link to here.<br>
<br>
I need an editable bar graph so that I can just go in, change the info, and not have to do anything on the site itself. What keeps throwing me off is two things:<br>
<br>
1 - WordPress.com doesn't let you use iframes. I shudder at the thought of using them to begin with, but they do fit the purpose. So I <em><strong>have</strong></em> to use a service that has an image output. Along the same lines, I can't install plugins so making the graph that way won't work either.<br>
<br>
2 - I really want something that has a single field for variable input. I've been using Chart Go, but when I use their "Modify This Graph" link all of the info for the graph is gone. So anything that doesn't do that would be great.<br>
<br>
The reason I'm looking for the single field, and not multiple like Chart Gizmo, is that I want to keep the stuff displayed in order. Copy/paste one user's info isn't a problem when I can just put it somewhere else in a list. But having the move almost everyone when there's a change just isn't going to happen.<br>
<br>
I'd also prefer an online solution so that I can use multiple computers. And free, especially since Chart Go is 90% of what I'm looking for anyway.<br>
<br>
Is Chart Go the best option I have? Is there anyone that fits my needs better?tag:ask.metafilter.com,2013:site.245294Wed, 24 Jul 2013 07:26:13 -0800theichibunHelp me convert this graph into a table.
http://ask.metafilter.com/243767/Help%2Dme%2Dconvert%2Dthis%2Dgraph%2Dinto%2Da%2Dtable
I have a bitmap of a chart (in polar coordinates) that I would like to convert into a format that some plotting package can recognize, and then retrieve values from the chart at specific intervals. How do I do this? I have a <a href="http://express27.org/articles/polar">polar chart here</a>, the link to which contains a description of how to use the chart, as well as the only chart I actually have.<br>
<br>
What I would like to do is be able to trace the curves as they appear on the chart using a bezier-curve drawing tool, and then I'd like to be able to output the following table:<br>
<br>
The x-axis would be "wind speed" and have one entry for each line on the chart (5, 8, 10, 14, and 20 knots).<br>
The y-axis would be "angle", from 0-180 in five degree increments.<br>
The value in each box in the table would be "boat speed" which is the radius of the curve for the corresponding "wind speed" line as it appears at the given angle.<br>
<br>
Eventually, this will end up in the <a href="http://www.letscreate.dk/letscreate/?q=node/300">file format specified here</a>, but first I am just interested in getting this into a plotting program that will let me enter these arbitrary curves (hopefully by placing my existing chart as an image and then tracing over it) into a polar coordinates space such that I can simply read r,θ pairs off the screen for the point under my mouse.<br>
<br>
I would like to be able to automatically generate r values at five degree increments along each of my lines, but I'll type the numbers in by hand if I need to.<br>
<br>
I am using a mac and would like to use the least expensive software that's capable of doing this, but I'm willing to buy some plotting package if it's reasonably priced. I have excel and I'm a programmer, so if I need to script some other package to generate output, I can probably do that, too.tag:ask.metafilter.com,2013:site.243767Fri, 28 Jun 2013 14:15:45 -0800tylerkaraszewskiChart help needed: How to show proportion between two values?
http://ask.metafilter.com/233257/Chart%2Dhelp%2Dneeded%2DHow%2Dto%2Dshow%2Dproportion%2Dbetween%2Dtwo%2Dvalues
What type of chart do I want to show that one number is several times as many as another? Putting a tall bar representing value x next to short bar representing value y shows that x is greater than y by x-y. (I realize that's a bit of an oversimplification.) What's the best way to show that x is greater than y by x/y times? I would love some examples.<br>
<br>
Bonus question that I should really know the answer to: if x-y is the "linear" relationship, what is x/y? Neither the "geometric" relationship nor the "proportional" relationship sound right to me.tag:ask.metafilter.com,2013:site.233257Wed, 16 Jan 2013 06:48:41 -0800Sock Ray BlueTurning user input into pie (charts)

WordPressFilter: I'm looking for a plugin/widget/codesnippet that will allow me to create a graph using input from the user. This seems really simple and I don't want to reinvent the wheel, but my Google-fu is taking the day off. Basically, I want the user to put numbers into one or more fields, then we apply our mathemagic formula to those numbers, then we give them a graph with the results. I tried looking along the lines of mortgage calculators, but no dice there either.<br>
<br>
I'd prefer to find a plugin for WordPress that will handle this, but I'm also amenable (to a lesser degree) to hacking together some solution in HTML5/js if that's a viable alternative.

http://ask.metafilter.com/211490/30%2Dminutes%2Daway
Are there any mapping applications that display all regions within a fixed distance from an input point? For example: from a given address in NYC, what are all the places I can get to in 30 minutes, via any combation of walking + public transit? So we're moving to NYC (yay!), and my wife & I are looking for housing. We're trying to stay within a 30 minute commute from her work, and I'm searching for possible neighborhoods based on subway & bus maps.<br>
<br>
Wouldn't it be nice, I mused, if I could type in where she works, and a tolerable commute time, and Google Maps or something would show all the places we could live within (any combination of) transit + walking distance? All the data's already there, on NYC MTA. Surely someone more clever than I has already thought of this and done it.<br>
<br>
Right? If not...I might take a crack at it. If the answer is no, this doesn't exist, then I have a follow-up question: I bet there's an algorithm in graph theory that returns a list of verticies within a given distance from a source vertex.

http://ask.metafilter.com/210758/How%2Dto%2Dmake%2Da%2Dtree%2Dgraph
Help me find software to make tree graphs. Looking for software package suggestions (mac or pc) that will produce something very much like a <a href="http://www.stat.lsu.edu/faculty/geaghan/EXST7037/Fall2007/SAS/Cluster/BreakfastCereal/tree.gif">tree graph</a>, from a table of data points stored in an excel file.<br>
<br>
I have several data sets in which a binary “division” event occurs, spawning two new events, and about 100 data points later (typically 1 hour separates each data point), each of these two new daughter events will then also undergo a division event spawning two new daughter events etc. The period between parent events and daughter events is important, and should be reflected on the graph in the distance between the parent and daughter events. I have a large excel spreadsheets of events and daughter events to input but have struggled to find a sufficiently flexible platform for making tree graphs. Any suggestions would be welcomed. Free software would be preferable but I am willing to pay if necessary.<br>
<br>
As a bonus, I would also like to display information about a secondary measurement associated with the 100 or so data points of each branch that separate a division event and a daughter event but am a little stuck as to how to visualize this. The Secondary measurements vary in magnitude between each parent and daughter event, typically forming a bell-shaped curve. Simplistically, I though that maybe the secondary measurement for the 100 or so data points could be represented as the thickness of the line connect parent and daughter events but know of no software that could implement this. <br>
<br>
Hopefully someone out there can understand this abstract description of my data!<br>

http://ask.metafilter.com/208882/Recommendations%2Dfor%2Dfree%2Dor%2Dcheap%2Dgraphing%2Dsoftware
Can you recommend free (or cheap) graphing software for Windows? Are there any good open source graphing packages out there? I am fed up of my presentations being full of ugly Excel-generated graphs. I use a range of bar charts, pie charts and line graphs, and generally they all (especially the pie charts) look ugly in Excel (I use Excel 2003 but am told by friends that the more recent versions look just as bad). <br>
<br>
This may be optimistic, but I'd prefer free as it's a fairly occasional use, but if a good quality product has a small, but reasonable, fee (e.g. not the > $500 cost of say Graphpad Prism) then I would still be interested. <br>

Where can I find taxonomies of the everything? When I was young, an encyclopedia had a taxonomy of essentially everything in a hierarchical form and discussed how inherently difficult it was to create it to organize the encyclopedia. <br>
<br>
Instead of a tree, it might actually be a graph (for those familiar with the concept in computer science). <br>

A taxonomy of known species is reasonably well documented but I'm wondering where I can find taxonomies of simply everything including species. The social world, health/medicine, etc, all the categories in the MeFi 'categories' and beyond. <br>

Is there an accepted way to graphically represent rates when small sample data is anonymized? I have a data set where a large number of points are "less than ten but greater than one incidents." <br>

If this were a population of 100, the rate would be within 1%-10%.

What are accepted ways for visualizing this example dataset for a journal or other "professional" endpoint? The graph I have in mind <a href="http://imgur.com/vzhgO">looks like this</a>, roughly speaking:<br>
<br>
• I have two datasets that I am comparing with two separate y-axes. For the purposes of illustration, higher values of variables 1 and 2 are "bad", lower values are "good".<br>
<br>
• The first dataset (green) is showing data results for variables 1 and 2 across all categories (x-axis, A to N).<br>
<br>
• The second dataset (red) is showing data results for variables 1 and 2 across a subset of categories (A to K).<br>
<br>
• The categories are continuous and equally distanced values, which is why lines are used instead of discrete points.<br>
<br>
<em>What I would like to do:</em><br>
<br>
I want to show that the second dataset (red) not only performs worse than the first dataset (green) after the first category, but that it cuts out entirely past category K.<br>
<br>
<em>What I am doing now:</em><br>
<br>
That red ball is supposed to be a visual indicator that would be explained in the figure legend. The ball could be replaced with a box or cross.<br>
<br>
<em>My question:</em><br>
<br>
What are other ways in which this kind of data comparison can be visualized, which follow accepted conventions for data visualization in modern scientific journals? <br>
<br>
I would like to avoid the "cheat" of using the red ball, since I would have to explain this in writing in the figure legend, and I don't want to confuse the inferences that the audience should derive from the figure. <br>
<br>
If there is something I can put in which other authors use as a matter of course, I would like to use that for less confusion. For example, should I draw a vertical line at category K, to highlight that cutoff point?<br>
<br>
I am thumbing through Tufte's books for inspiration, so there's no need to point me there unless there's a specific book and page number that you think meets the criteria for a demonstrative example. <br>
<br>
<em>Please note</em>: I would greatly prefer specifics and pointers to figures in journal articles or textbooks, etc. as examples, as opposed to generalities. (I am <strong>not</strong> looking for philosophical approaches to visualization, so much as concrete examples of this problem being solved elsewhere.)<br>
<br>
In particular, if you have examples which communicate the same dimensions of data results which are not line graphs, but are a different design that is clearer, more efficient and more elegant, I would be grateful for that kind of inspiration.tag:ask.metafilter.com,2011:site.189148Fri, 24 Jun 2011 15:54:40 -0800Blazecock PileonSo how do people make those nice graphs?

What are some super simple graph making programs? I am creating a research proposal for one of my grad school classes. The class has a heavy focus on shewart control charts. My paper is due between Saturday and Monday. I understand the math behind the control charts but I have been trying to use the freeware shewhart control chart for excel but sadly it is beyond me. My actual thesis proposal isn't due for many months so I'm confident I can figure this out by then but what can I use in the meantime that is super simple. A bonus for any super easy programs that can do histograms, or other graphs. <br>
<br>
Also if you can explain the free shewhart program for excel that would be helpful. n and k values particularly. And what values need to be modified, obviously the original ones but which others are not adjusted automatically? Finally, the original data that comes up with the table confuses me with regard to the range chart, what is with this? <br>

How should I display this data? Chlamydia screening rates among 20 clinics, cut a few different ways.
Big picture question: resources for really good charts and graphs? Yes, I went to a Tufte class today.<br>
<br>
So it got me thinking: how can I best visualize this data? I am looking at chlamydia screening of sexually active young women: twenty clinics, patients split between internal medicine and pediatrics PCPs, and patients included either by having a hormonal birth control prescription or some other reason. I want to get my audience discussing the variation and thinking about ways to improve.<br>
<br>
I know I could do this with a bunch of different displays (a graph comparing the rates of the different clinics, a page comparing the clinics pediatrics only, etc etc) but I wonder if there is something more clever.<br>

I've been asked to teach a week at a summer university. Help me to design the most awesome computer science/discrete math course ever. So I want to teach a class on graph theory/discrete math, but in a fun way. It's for comp sci with 1 year of background, not mathematicians. I want to link math with crime :-), like in Numb3rs.<br>
<br>
This is what I've already half-prepared:<br>
- First lecture: what is a graph, adjacency matrix, degrees, closeness, betweenness: Analysing 9/11 networks (Ata scores high in all those "scores", so my students will identify him)<br>
- Last lecture: Networks and random graphs: Bioterrorism 101.<br>
<br>
Everything in between is open.<br>
<br>
I've already done some research (especially on Numb3rs), but most topics are either not very-well fleshed out, or too low-level. There are teaching resources by Texas Instruments, but they are rather infantile. Still, a starting point.<br>
<br>
What I'm thinking about topic-wise (not neccessarily everything, not in that order..):<br>
<br>
- Bipartite graphs, trees, spanning trees, breadth-first<br>
- Matchings, marriage theorem<br>
- directed graphs, TSP (For this, I probably use this idea: http://education.ti.com/xchange/US/Math/AlgebraII/7860/Act2_AntsGoMarching_EndofWatch_final.pdf)<br>
- Euler, Hamilton<br>
- Greedy-Algorithm<br>
- Dijkstra (This will probably be a real-life example of a hijacked car - which route will they take? Also, there is this modified Dijkstra with DNA alignment, but I would have to research on that). <br>
- MaxFlow <br>
<br>
Ideas which involve some coding are okay. I do have time to research and create lesson plans. I do have motivation to do so. However, I do not have many ideas.<br>
<br>
Thanks a lot!! :-)tag:ask.metafilter.com,2011:site.176938Thu, 27 Jan 2011 23:30:38 -0800mathemagicianWhat kind of graph plot am I looking for?

I have a series of tables describing a set of data and their values for certain points in time. I want to create a multi-line chart from this data so I can see the growth curves. Is there a name for this kind of plot? It must be a solved problem and some tools to do this but I can't google for it if I don't know the name of what I want. Specifically, while doing some program debugging, I've been profiling of memory usage of my application. I want to see what objects are growing the fastest in order to pinpoint this memory leak I'm trying to track down. I tried to be generic in my question since my use case isn't really what I want know here.tag:ask.metafilter.com,2011:site.176758Wed, 26 Jan 2011 01:22:30 -0800rdhattFaces

Newbie Graph Theory: How can I find all the faces of a planar undirected graph? Or, what I think is equivalent, all of the chordless cycles (cycles in which no two nodes are connected by any path other than a subset of the cycle) . <a href="http://stackoverflow.com/questions/4022662/find-all-chordless-cycles-in-an-undirected-graph">I'm fairly sure this is wrong</a>, as it will find cycles whose elements are connected by non-cycle paths if those connections aren't direct.<br>
<br>
I have a feeling spanning trees are involved...tag:ask.metafilter.com,2011:site.175837Sat, 15 Jan 2011 19:36:55 -0800phrontistHow much video is recorded per year, at what speed is this number increasing?

Does any group track the amount of video footage captured per time unit? Searching for a source that would help answer the question "how many hours it would take to watch all video recorded in the last year or decade, ? Or prior years or decades?" Camera's are becoming more and more ubiquitous, (handheld single purpose video cameras, cell phones, professional cinematic camera's, CCTV, traffic lights, atms, etc.) Looking for statistics on the hours of footage captured by each or all of these groups as a function of time.<br>
<br>
I'm aware that private video is an incredibly hard thing to track scientifically, but does anyone have a link to a related reference? I've found figures on the amount of you-tube uploads (in 2010, 20 hours uploaded every minute,) but wonder if there's anything that would include statistics from CCTV footage or the movie industry. Conjecture is less desirable then factual sources, even if only marginally related. I've searched for these figures hoping literature from video analysis software marketing would provide something but google-fu is failing me. Help me ask mefi you're my only hope!
