TeeChart tooltip does not work on Point-series.

[mks-ydi]

Hello Team,

We use TeeChart for .Net with version 3.5.3225.32185.

I make a "Points" series with Triangle style for example added to a chart. and then add a tooltip tool(SeriesHotspot) to the chart.
the result is that The toolltip tool is not ok for Triangle,SmallDot,Sphere,Star and so on. but it is only ok for Circle and Rectangle shape.

please help me
thanks,
Carol.

Hi Carol,

I have been able to reproduce the issue here and added it (TW77015716) to the defect list to be fixed. This only occurs with WebForms applications. It works fine in WinForms with MarksTip tool.

Could you provide a temporary solution?

Hi Carol,

Yes, a workaround is using Line series with visible pointer and no visible pen, for example:

Code: Select all

    protected void Page_Load(object sender, EventArgs e)
    {
      Steema.TeeChart.Chart chart1 = WebChart1.Chart;

      chart1.Aspect.View3D = false;

      Steema.TeeChart.Styles.Line line1 = new Steema.TeeChart.Styles.Line(chart1.Chart);
      line1.FillSampleValues();
      line1.Pointer.Visible = true;
      line1.LinePen.Visible = false;
      line1.Pointer.Style = Steema.TeeChart.Styles.PointerStyles.Triangle;

      Steema.TeeChart.Tools.SeriesHotspot hotSpot1 = new Steema.TeeChart.Tools.SeriesHotspot(chart1);
      hotSpot1.Series = line1;
    }

That's really great. Why I can't come up with this amazing idea.
Thank you a lot for your help.

dear Narcís,

Thanks for your reply. the solution is so smart,and it works very well.
but
I have one question about the diffrences between the "points" series and the "line" series(when only show points,line hiden).

I am worry that there is diffrence(show diffrent result) exist on some situations that i can not imagine now.

for example, inner sort mechanism ,points order on x-axis/y-axis, something like that.


Thanks

Hi Carol,

No, there's no important difference I can think of now. Sorting is the same for Points, Line and most other series.
