Charts

If you are us­ing re­Struc­tured­Text and in­stall py­gal, Niko­la has sup­port for rather nice chart­s with lit­tle ef­fort, and i’s even semi-in­ter­ac­tive (hover your point­er over the leg­end!):

Here’s how it work­s:

  • Next to the di­rec­tive, use the chart type you want
  • Any op­tion you can set in a chart? Use it like :ti­tle: in this ex­am­ple. Syn­tax on the val­ue is just like in the py­gal ex­am­ples.
  • For each da­ta se­ries do it like the line that says Fire­fox in this ex­am­ple. The first el­e­men­t is the la­bel, then comes the da­ta.

Easy, right? Please ex­plore the py­gal site for more in­for­ma­tion, and just ­take this ex­am­ple and tweak stuff.
