Can't "shwo legend" when using an expression as color

[nicolas_martin]

Hello,

On a chart, I can display the legend if the color is auto, fixed, or by dimension.

But when I use an expression for the color, the option to show the legend is not available.

Is there a way to do so?

Thank you.

with legend.

Whereas with an expression we can't ask for the legend:

that gives

without legend.
