Hello,
I am working on an WPF application dedicated to Data Mining and Modeling. One critical information we have to display on chart is Confidence Intervals: [Ymin, Ymax], and one interesting way to do that is to fill the area between Ymin and Ymax curves (see grey area in attached screenshot). Brushes and opacity will be great companion for that (in case of multiple lines at a time...)
Anyway, according to my understanding of Infragistics Wpf Chart, this type of feature is not in place but might be done ... So, could you please comment on that and tell me How to achieve this type of representation?
Another missing feature is around error display (error bars in Excel). Any plan on that one ?
Best regards
Rodolphe
Currently, XamChart doesn’t support Range chart. But you can try using something like:
<igChart:XamChart x:Name="xamChart1">
<igChart:XamChart.Series>
<igChart:Series ChartType="StackedArea" Fill="Transparent" Stroke="Transparent">
<igChart:Series.DataPoints>
<igChart:DataPoint Value="50" />
<igChart:DataPoint Value="10" />
<igChart:DataPoint Value="100"/>
<igChart:DataPoint Value="20" />
<igChart:DataPoint Value="30" />
</igChart:Series.DataPoints>
</igChart:Series>
<igChart:Series ChartType="StackedArea">
<igChart:DataPoint Value="150" />
<igChart:DataPoint Value="110" />
<igChart:DataPoint Value="200"/>
<igChart:DataPoint Value="40" />
</igChart:XamChart.Series>
</igChart:XamChart>
If you want to request the error bars as an official feature then please visit this page:

HI,
Thank for your prompt answer.
Nevertheless, StackedArea series can not be combined with ScatterLine series.
And I do need to plot both confidence intervals (stackedArea fits my need for that, even if Axis x might become a problem) and the value itself (blue line on the attached screenshot in my first post).
Any workaround to have both on the same chart ?
Thank you in advance
You can add and line series after stacked areas:
…
<igChart:Series ChartType="Line" StrokeThickness="3">
The problem here is that you can't add both positive and negative values. It seem that we need to add a real range chart.
