Strange behavior on fastScatter chart

[Renard Laurent]

Hello,

I have noticed that for Fast Scatter chart Type "Segment.CorrespondingPoints[0].DataPoint" refers only the first point. Checked on ChartMouseEvent and on ToolTip.

On normal scatter the behavior is normal.

Is it something I should expect or it is a bug ?

Then how can I get the value of a given point with fastScatter and with the ChartSeries event (I mean I don't want to use a reference of my IInput element as we can do using the traditional MouseEvent)
?

Thanks for your help,

Laurent

Hi Laurent ,

Thanks for choosing Syncfusion products.

The fast chart types are drawn as a single segment, So the tooltip displays only the starting point value. This is the behavior of the fast chart types and it is not a bug.

Please let us know if you have any questions.

Hello,

Thanks you for your reply.

So does it mean that for Fast Scatter, if I set the template for the ChartSerie I will only see the first point,

or if I try to get the corresponding point on ChartMouseEvent I can only refer to the first point ?

Thanks you very much

Hi Laurent ,

Thanks for choosing Syncfusion products.

In the mouse move event we can access the corresponding points value using PointToValue() method of ChartArea. Based on your requirement we have created a simple sample. Please download it from the following location.
