Move trackball freely

[Alex Tarragó]

Is there a way to move the trackball freely across the entire chart, without snapping to each x-axis point?

We’ve managed to combine the crosshair and trackball behaviors, but it still locks onto individual x-axis values.

Is there a way to achieve free movement using this library?

Hi Alex,

You can refer to our Knowledge Base (KB) article that explains how to customize TrackballBehavior and CrosshairBehavior in the SfCartesianChart. The documentation includes a sample, and you can modify it based on your specific requirements. Let us know if you need further assistance.
