Hi Graham,

I am also using similar kind of feature. I am able to display chart as tooltip and i am setting ToolTipService.ShowDuration="60000"  property to datapoint, but it is not displaying the tooltip for 60 seconds, it is displaying for only 5 seconds. Following is the code i am using. Please help me in this.
