Me.UltraChart1.Tooltips.Display = TooltipDisplay.Never
The Chart control generally renders charts at an exceptional speed; however, users who are plotting a large number of points may want to set the Display property of the Tooltips object appropriately to optimize performance. Additionally, not generating image maps will assist the element in rendering quickly.
The sample code below demonstrates how to set the Display property to disable ToolTips.
In Visual Basic:
Me.UltraChart1.Tooltips.Display = TooltipDisplay.Never
In C#:
this.ultraChart1.Tooltips.Display = TooltipDisplay.Never;
