showing correct tooltip when there is a bar and scatter series on one chart

[nickm]

Hi,

I have a combination chart containing 1 bar series and multiple scatter series. When a scatter series marker appears in the same area as the bar the tooltip information for the scatter marker can't be accessed. Only the bar tooltip appears. I have tried senttoback() on the bar series and sendtofront() on the scatter series but it made no difference. Is there a way to make this work?

 

cheers

I can't replicate the issue. In a combination chart with bar and scatter, I can see the tooltip of the scatter series as well. 

In a chart with 3 series, I set chart gallery to scatter and the last series to bar gallery.

Chart1.Data.Series = 3;

Chart1.Data.Points = 5;

Chart1.Gallery = Gallery.Scatter;

Chart1.Series[2].Gallery =

Gallery.Bar;

Make sure you have the latest service pack installed:

If you still have problems with the latest service pack, please provide some sample code.

The problem I am having is the tooltips for the scatter series do not appear only for points where the scatter series appear within the bar region. outside of that they appear.

Tooltips seem to work fine even for points within the bar region. Update to the latest service pack (7.0.2845) and then try.

 Instead of setting the series gallery individually, set the gallery of the chart to scatter and the last series gallery to bar.

Chart1.Gallery = Gallery.Scatter;

Chart1.Series[5].Gallery =

Gallery.Bar;
