claude-code - 💡(How to fix) Fix [BUG] /usage → Stats → Models, 'Tokens per Day' chart does not render lines in per-series colors

What's Wrong?

On /usage → Stats → Models, the 'Tokens per Day' chart renders all model lines in magenta. Cause: the per-series colors are passed through a converter that only parses rgb(r,g,b) and falls back to hardcoded \x1B[35m (magenta) for the theme's ansi:-named colors; the legend bullets use the raw theme color via a separate path and render correctly.

What Should Happen?

The per-series colors are passed through a converter that only parses rgb(r,g,b). The legend bullets use the raw theme color via a separate path and render correctly. The code computes a separate line series per model and explicitly passes a per-series colors array to the plot. The intent is right there in the source. It only fails at the last step because D$6 can't parse the theme's ansi: colors and falls back to magenta.
