Graphics, Figures & Tables ⇒ Macros for piechart, barchart, spiderweb

[koubi]

Hi,

I spent few days trying to "macrofy" the rendering of piechart, barchart, and spiderweb from raw data input wihtin the document. I wanted some high level API like

The above is how I currently use the macros I implemented. I had to use xintForPair for the last one, maybe foreach can be use instead... well although the spiderweb rendering isn't that short (few seconds...), it's fine for me, and I just wanted to share.

Hi koubi,

welcome to the forum!

Very interesting macros. Thank you for sharing! I added images to your post, so readers can immediately see the examples as compiled images too.

When I tested the bar chart example, I got

! Undefined control sequence.
\XINT_expr_scanfunc_panic ...rror:bigtroubleahead
(0\relax
l.94 }

but I must admit that I tested it on a PC with a TeX installation of 2014. I will test it again on TeX Live 2016 at home.

Stefan

I compiled that on archlinux with texlive from repo. It also works with latest stable miktex on windows.
