StepAreaSeries is ignoring Minimum value of NumericalAxis
I have a chart that maps Y values between -100 and -10. If I use a LineSeries everything charts as expected. When I use a StepAreaSeries it appears to attempt to draw the X-axis minimum at 0, which is off the top of the chart. How do I get the StepAreaSeries to use the correct X-axis minimum of -100 to fill the StepAreaSeries to the bottom of the chart instead of drawing the area to the top of the chart? Thanks!
And here is the xaml:
<syncfusion:SfChart Palette="GreenChrome">
<syncfusion:SfChart.Header>
<TextBlock Text="Signal and Noise" Style="{DynamicResource _graphHeaderText}"/>
</syncfusion:SfChart.Header>
<syncfusion:SfChart.PrimaryAxis>
<syncfusion:DateTimeAxis Style="{DynamicResource _dateTimeAxisStyle}"
Maximum="{Binding ItsChartMaxTime}"
Minimum="{Binding ItsChartMinTime}" />
</syncfusion:SfChart.PrimaryAxis>
<syncfusion:SfChart.SecondaryAxis >
<syncfusion:NumericalAxis Style="{DynamicResource _numericalAxisStyle}"
Minimum="-100" Maximum="-10"/>
</syncfusion:SfChart.SecondaryAxis>
<syncfusion:StepAreaSeries ItemsSource="{Binding ItsTimeSegmentCollection}"
StrokeThickness="1"
XBindingPath="ItsTimestamp"
YBindingPath="ItsRssi" />
<syncfusion:StepAreaSeries ItemsSource="{Binding ItsTimeSegmentCollection}"
StrokeThickness="1"
XBindingPath="ItsTimestamp"
YBindingPath="ItsNoise" />
</syncfusion:SfChart>

<chart:SfChart x:Name="chart">
<chart:SfChart.PrimaryAxis>
<chart:DateTimeAxis Origin="-100"/>
</chart:SfChart.PrimaryAxis>
<chart:SfChart.SecondaryAxis>
<chart:NumericalAxis Minimum="-100" Maximum="-10"/>
</chart:SfChart.SecondaryAxis>
<chart:StepAreaSeries ItemsSource="{Binding Data}"
XBindingPath="XValue" YBindingPath="YValue"/>
</chart:SfChart> |
