Hi
Bhadhrinaath,We're
currently in the process of implementing a feature that allows users to select
a set of points in the Scatter Chart by drawing a rectangle around them. While
this feature is still in progress, we've developed a demo video showcasing its
functionality.In
this upcoming feature, users will be able to select scatter points by drawing a
rectangle around them. The selected points will be highlighted within the
rectangle, providing users with an intuitive way to interact with the chart.We've
attached a demo video to this response for you to preview how this rectangle
selection functionality works. We're diligently working on completing this
feature, and it will be available in an upcoming release.If
you have any further questions or need assistance, please don't hesitate to
reach out to us.Best
regards, Dhanaraj

Thanks. Can you provide Square or Circle as a selection option?

Also, would like to highlight the selected points in a different color.

And a click on a point to select/unselect a point would be good too.

When is the next release btw?

Thanks

Hi Bhadhrinaath,For the selection options, we currently offer the ability to select data points using a square, which can be achieved using the rectangle options. However, we understand your request for circular selection options as well. We have already created feedback for this feature and add it to our feature request list. You can track the status in the following feedback portal link.Feedback Link: Retrieve the data point collection in the desired area in .NET MAUI SfCartesianChartCurrently, we have migrated the chart feature from Xamarin.Forms, where we provided the retrieving data points feature by using rectangle only. We will prioritize the features in every release based on the demands, and we do not have an immediate plan to implement this feature using circle since we committed to already planned work. So, this feature will be available for any of our upcoming releases.Please cast your vote to make it count, and if you have specifications of retrieve data points using circle or suggestions for the feature request, you can add them as a comment in the feedback portal.Regarding the highlighting of selected points in a different color, you can achieve this by using the DataPointSelectionBehavior in the Scatter series and setting the Type to Multiple helps to select the multiple data points. You can specify a custom brush for highlighting selected points using the SelectionBrush property. We have provided a code snippet below for your reference: Output:Regarding the release schedule, the next volume release is scheduled for mid-June 2024.If you need more assistance, feel free to ask. We’re here to help.Regards,Dhanaraj Rajendran.

Hi Dhanaraj,

So, is it correct that in your June release you would include the ability to draw a Rectangle in the chart and retrieve the points within the Rectangle?

And could you create a new Feature Request for Circle based selection please, I will up vote it. (It would be better as its own Feature Request rather than being a comment in the other Feature Request you pointed me to).

Thanks

Thanks Dhanaraj.1) One last question, can you update that sample video you provided to make the selected points highlighted? That would then be useful to make a decision in our team.Also, interestingly, I can't seem to be able to upvote this FR:

Support for retrieving data point collection by passing circle

When I click on it, it goes to 0 from 1.Thanks

Hi
Bhadhrinaath,We have updated the sample
video to demonstrate highlighting the selected points when clicked. You can
download and review the updated video attached to this response.Regarding the feature
request for "Support for retrieving data point collection by passing
circle," you are correct that you cannot upvote it multiple times. Once
you have upvoted a feature request, it remains at 1 vote from your account.Please find the attached
video for your reference. If you need further assistance, don't hesitate to
ask.If you need a demo video of highlighting the selected data points using the Rectangle selection,
we need time to prepare the sample with that use case and will provide a demo
for that on or before two business days (30/04/2024).Regards,Dhanaraj
