Hi,
I have a requirement to somehow break the line if a datapoint is marked as invalid. There are 2 questions:
- How to mark it, i.e. can I use a special Y-value (null, infinite, ..) to use?
- How to draw it?
a) if no line at all should be drawn between 2 valid data points when an invalid one is between them?
b) if a dashewd line should be drawn in this case?

About the dashed line, you can try using:
<igChart:XamChart>
<igChart:XamChart.Resources>
<Style TargetType="{x:Type Line}">
<Setter Property="StrokeDashArray" Value="2, 1" />
</Style>
</igChart:XamChart.Resources>
<igChart:XamChart.Series>
...
I guess it would draw the whole line dashed?
Unfortunately, this works only on the chart level. This is because the Series is not the container in which the lines are rendered.
I did a test for the solution you provided. The dashed line style can only be applied on the chart level. That means if have two lines in the same chart, both lines are drawn as dashed line. I can not apply the style to the series level to drawn one line as dashed line and another line as non-dashed line.
Is there any way that I can draw one line as dashed line and another line as non-dashed line in the same chart? Thanks!
FYI. Following is the code I tried and the result is both lines are drawn as non-dashed line. The dashed line style does not take effect on the series level.
<igChart:XamChart Name="testChart" Grid.Row="2"> <igChart:XamChart.Axes> <igChart:Axis Name="testAxis" AxisType="PrimaryX" AutoRange="False"/> <igChart:Axis AxisType="PrimaryY" AutoRange="False" Minimum="0" Maximum="100" Unit="20"/> </igChart:XamChart.Axes> <igChart:XamChart.Series> <igChart:Series Name="seriesA" ChartType="ScatterLine" Fill="Purple" StrokeThickness="2"> <igChart:Series.Resources> <Style TargetType="{x:Type Line}"> <Setter Property="StrokeDashArray" Value="2,1" /> </Style> </igChart:Series.Resources> </igChart:Series> <igChart:Series Name="seriesB" ChartType="ScatterLine" Fill="Blue" StrokeThickness="2"> </igChart:Series> </igChart:XamChart.Series> <igChart:XamChart.Legend> <igChart:Legend Visible="False"/> </igChart:XamChart.Legend> </igChart:XamChart>
Yes, it will draw the whole line dashed.
