  this is my trackball. when the control is in the middle of the screen. The trackball window hides because the size is big. How can it be fixed when the control is in center. I have also attached the images.

What strategies can be implemented to dynamically adjust the position of the trackball content in the SfCartesianChart so that it remains visible, especially when the control is centered on the screen (slope)?

Hi, I’m new to Syncfusion and I’m having a similar issue.

When my trackball control is positioned in the center of the screen, the trackball window becomes partially hidden because the popup size is too large.


Is there a way to force the trackball window to stay fully visible even when the control is in the center?

Hi Restling gavew,

 

Since we are using a custom container to display the trackball tooltip, you can customize it as needed. The custom trackball container is rendered using the method _buildTooltipContentForWinAndLoose in the provided sample.

 

Please note that this issue is already being addressed in the following forum thread:

Kindly review the sample and update the custom trackball tooltip container based on your requirements.
