Idea of using legends as on/off buttons

[Zhu]

Hi,

Here's the  idea, click a legend to turn the referenced chart off ( by changing the isVisible property), click again to turn it on.

I tried it in onLegendTapped and it works.

Though, when a chart is turned off, I hope it's legend change to a customizable color like grey instead of white, and still show it's title, is that possible?

Hi Zhu,

Thanks for your patience.

Your requirement can be achieved with the help of the legendItemBuilder property in the legend, which is used to render a custom widget instead of an actual legend. Here we have rendered a custom shape widget with a series color and changed the color of the widget based on the series visibility. We have shared the sample below for your requirement, you can modify the sample as per your requirement.
