[SfCircularChart] Is there a way to clear the selection from the selectionBehavior when I tap off the graph?

[LuisCampos97]

Hi!

Is there a way to clear the selection from the selectionBehavior when I tap off the graph?

My idea was whenever I selected a portion of the graph the tooltip and the selected portion would appear, and when I touched outside the graph, I would clear the selection and disappear the tooltip.

Hi @LuisCampos97,

Greetings from Syncfusion. We have analyzed your scenario with the provided information at our end and we have achieved your requirements by using a simple workaround with help of the onPointTapped and onChartTouchInteractionUp callback events available in the SfCircularchart. In the sample, we have used the onPointTapped and onChartTouchInteractionUp events to check whether the user touches outside the chart or on the chart data point and based on that, we have deselected the selected point and also hiding the active tooltip of that point using the public methods of SelectionBehavior and TooltipBehavior available in the chart. We have also attached the workaround sample below for your reference.

sample: gh234_sample.zip

Please check with the above-attached sample and revert us if you still have further concerns.

Sriram Kiran

Hello again, and sorry for the inconvenience.
But with this new update on syncfusion_flutter_charts, your implementation will stop working. The selection does not disappear when you tap outside the graph, only the tooltip disappears.

@SriramKiranSenthilkumar Can you please review through the sample you created above with the new update?
Thank you!

Hi @SriramKiranSenthilkumar,
With this new update, most of the problems of this issue have been solved.

But with that sample you made, when you click the second time on the same portion, it clears the selection and shouldn't be.

Can you help me, please.
Thank you!

Hi @LuisCampos97 ,

Thanks for your revert. And we have analyzed on clearing selection when selecting the same portion on the second attempt. As of now, we don’t have support for not to deselect when selecting on the same portion, by default when the selected portion is tapped on the second attempt, it will get deselected. So, we have considered your request as a feature request and logged for the same. This feature will be available in any of our upcoming releases yet to come and you can track the status of the feature from below feedback portal.
