PointXY - Tooltip
Posted: Thu Apr 04, 2024 1:40 am
I would like to inquire about how to resolve the tooltip error.
When you hover the mouse pointer over the red square box area, a tooltip will appear.
I would like to inquire about a solution so that the tooltip is displayed only when the mouse pointer is placed on the chart pointer.
Demo source and image are attached.
thank you
