Hello,

in TChart I use TDataPointHintTool. I discovered (see attached screeshot) that Hint is triggered also in outside of frame (frame -> area where series is plotted). This happens at upper and bottom but not at left and right sides of frame.

Is this OK or bug?

Sorry for my bad English.

You are probably working with DistanceMode=cdmOnlyX of the DataPointHintTool; with cdmOnlyY the hint would appear if the mouse is at the left or right outside the series region.

I am not sure if this is really a bug, but I can imagine that users could be surprised by this behavior. Therefore, I added a new property "MouseInsideOnly" to TDatapointHintTool and TDatapointCrosshairTool (in fact, it is implemented already for their ancestor TDataPointTool, but I think the other datapoint tools do not need it). With "MouseInsideOnly" set to true the hint does not appear if the mouse is outside the plotting frame.

"MouseInsideOnly" helped. Thank you.
