It's free-open-source from https://veusz.github.io/.
It's menu driven, fairly easy to use and quite flexible. I was originally trying to do this graph entirely in R/ggplot as a self-teaching exercise but gave up (for now). If you're okay with R you should have no problems with Vuesz.
I used R to grab the data online and process it into a year,age,rate table which I imported to Vuesz and created an image and contour.

It's a freeware front-end for python which I find much faster to use for plotting complex data. It has all the beauty and customisability of python plots, and I can get students up and running and using it in an hour.
The last time I was giving Labplot a try it had problems while exporting plots as vector graphics. Somehow it pixelated every marker while the rest persisted as true vector graphic. Maybe it is resolved in the meantime.
For everyone looking for a similar program, I can recommend having a look at Veusz. It seems so have similar features (plots of different kind, histogram and best fit calculations, scriptable via Python). I use it daily for my work and haven't found anything comparable to it.
In the manual you can read (page 9): "Veusz allows dates and times to be formatted using %VDX where X is one of the formatting characters for strftime"..." These include"..."H hour as 00..23"..."M minute as 00..59". So, with that in mind I tried with "%VDH%VDM" (without quotes) in the Format field of the Tick labels formatting of the X axis. It works as expected. I think it's worth mentioning that I imported data from CSV and I set X values as date-time when importing (so Veusz knows it is a date/time and not a label or a numeric field).
I didn't found any pie chart related examples on the Veusz example page, therefore I think that is not a function of veusz.
I mean there could be workarounds such as calculating the fractions manually and plotting them in polar coordinates, but to be honest I don't think it's worth it.
LibreOffice Calc should be able to do pie charts if you really need one.
Eh, so far I've just been using a rudimentary Python script with PRAW to scrape post histories into csv format, messing around with the data in spreadsheet form and then using Veusz for the graphs. Anyone with enough Python skills to get PRAW up and running could do the same.
The real trick would be in somehow mathematically proving that multiple accounts are the same person, presumably through a combo of metadata and linguistic analysis? Which is part of why I made this post, in hopes that someone with a legitimate background in these types of analytics might chime in at some point.
That’s pretty nice. I have never heard of Igor. I just did a cursory google of it and it looks like a plotting software...
Not sure what, or if you, paid for it.... but have you looked at:
I think it’s free... and my understanding is that it is supposed to compete with the top plotting softwares like Origins, and I suppose Igor now that I know what it is 😅
Thanks for sharing. If anyone else is still looking these posts.... it’s not my intent to diminish the work/effort done by students who received the awards.... I have no doubt that they’re all excellent. The main reason why this upsets me is that a majority of these institutions already provide tuition & fees funding PLUS stipends of some form.... I personally think that if the NSF wanted to truly promote STEM across all institutions they wouldn’t cluster their awards at the top ones.... who knows.... perhaps if a little more of these funds were to flow into more average universities it could light the proverbial fires for STEM participation at those universities... just my opinion, and without more data one can not conclude this with any certainty.
Among the completely free options, I have been satisfied with Veusz (pronounced 'Views') in the past. Several of my published papers contain graphs made with that program, and I thought they looked professional. There is a learning curve, but it's not nearly as steep as Matlab, R, or gnuplot.
I sort of figured it out- found a free plotting package called Veusz that's able to plot this sort of thing really easily.
Would be nice to be able to do in Excel but now that I've found this other software I may start using it for a lot more of my graphing work.
There's also the function plotting widget for plotting a function surface directly, or a function in 3d coordinates.
Veusz 2D datasets have an associated binning, so when you construct it you need to provide the xrange/yrange or xgrid/ygrid options: https://veusz.github.io/docs/manual/api.html#setdata2d
For the colormap, you need to provide a 2D dataset giving the color value (default 0 to 1) under the "Color data" setting.
