Chart colors problem

[jszczerbinsky]

The colors on the chart are different, than the ones in the legend, can't easly understand which line corresponds to which time control

That's a bit tricky - I am using mermaid.ai charts https://mermaid.ai/open-source/syntax/xyChart.html, and did not find a possibility to add the "color legend" in the chart. Now, in dark mode, colors are inverted, and my selfmade color legend doesn't fit.

As a workaround I added a dark mode color legend that helps a little, but I'm not really happy with this solution yet: https://github.com/computer-chess-index/cci/blob/main/engines/Zeppelin.md

So I'll make up my mind to find better solutions, and would be happy for suggestions in the meantime.
