Is there a way to remove Tooltips on the lines in the ScatterLine charts. The lines seem to be copying tooltips over from the markers but I am not sure which ones. I don't wan't tooltips on my lines just on the Markers or Data Points.
The tooltip on the line comes from the first marker. Unfortunately, you are not able to remove the tooltip only from the line, you need to remove the tooltip from the Data Point.
I am using a marker template to customize the appearance of markers, and in a marker button click I need to get back to the underlying data object that is presented by my own custom object that inherits from a data point. The only way I could find to get back to my custom data object was to fill the tooltip with custom indexing information. So I don't think I can remove the tooltip from the Marker/DataPoint without breaking my Marker Button Click Handler.
Details of what I have done can be found in the following links:

Below is my MarkerTemplate
<DataTemplate x:Uid="DataTemplate_1" DataType="{x:Type igChart:MarkerTemplate}">
<RadioButton x:Name="ChartMarkerButton" x:Uid="ChartMarkerButton1"
Style="{StaticResource MarkerButtonStyle}"
Click="Marker_Button_Click"
ToolTip="{Binding Path=ToolTip, Converter={StaticResource MarkerButtonToolTipConverter}}"
Loaded="ChartMarkerButton_Loaded"
/>
</DataTemplate>
In my MarkerButtonToolTipConverter I can control the tooltip for the Marker, and make it presentable or blank.
Is there a way to do something like this for the line?
Yes, I understand this, but the problem is the same - the tooltip for the line comes form the first DataPoint and with our current public API is not possible to remove the tooltips only from the lines.
