I have a chart with 3 series in it. All of the series are shown in the legend of the chart and allowed to be toggled on and off.
Is it possible to prevent from the last visible series to toggled off?
I'm adding an example main to simulate what I'm asking you about and also a video showing the current behavior,
the files contain the main.ts file and the pubspec.yaml used for the demo shown in the video.
We are validating your requirement at our end and will update further details in one business day.
Greetings from Syncfusion.
We don't have
direct support for achieving your requirement. However, the requirement can be
met by clearing the toggled series dataSource. We have shared a sample for your reference below.
Thanks for the replay, this is what I was looking for thank you.
