How to show tooltip when segment is underneath axis line of WPF Chart (SfChart)?

1 min read

When the axis is moved into the chart area using the Origin  and ShowAxisNextToOrigin  properties, any segment can be rendered near or underneath this axis, and the tooltip is not displayed for that segment. If you want to display the tooltip, you need to set the IsHitTextVisible property to false for that axis in WPF Chart (SfChart).


[XAML]

<chart:SfChart.SecondaryAxis>
      <chart:NumericalAxis ShowAxisNextToOrigin="True" Origin="2" IsHitTestVisible="False" />
</chart:SfChart.SecondaryAxis>

[C#]

this.sampleChart.SecondaryAxis.ShowAxisNextToOrigin =true;
this.sampleChart.SecondaryAxis.Origin = 2;
this.sampleChart.SecondaryAxis.IsHitTestVisible = false;

 Output

WPF Chart Tooltip displays underneath axis line
