XYChart not allowing legends

[jgclark]

Description

[Doesn't quite fit any of the issue categories; this is more a suggestion than a bug.]
According to the documentation the excellent new XYChart doesn't have a way of showing series labels or legend. However the initial proposals for such a chart type did include such labels, and all graphing packages include this option.

Steps to reproduce

Code Sample

Setup

• Mermaid version: 10.8.0
• Browser and Version: n/a

Suggested Solutions

In the same way that a Y axis definition can include a title (y-axis "Revenue (in $)" ...) allow a name after the series name: line "Sales" [...].

it would be awesome to have this possibility, whatever the syntax according to feasibility.

Would be super useful due to mermaid being essentially the only way to show charts in github's markdown contexts (unless you want to export charts from some other graphing package).

In the mean time, I have been doing this for a legend just after the chart:

Legend:

• something1
• something2
• ...

(using https://placehold.co to generate the square colour images)

Oh, wow, that's smart. I had no idea this was possible.

But definitely a hack we don't want to have to live with for a long time.
