Hi! I have problems with visible range managing of a polar plot
The code in xaml:
<s:SciChartSurface graphModule:PlotLengthHelper.PlotLength="{Binding PlotLength, Mode=OneWayToSource, UpdateSourceTrigger=PropertyChanged}"
x:Name="ChartSurface"
SizeChanged="ChartSurface_OnSizeChanged"
ChartTitle="{Binding ChartTitle}"
s:ThemeManager.Theme="BrightSpark"
Annotations="{s:AnnotationsBinding Annotations}"
RenderableSeries="{s:SeriesBinding Series}"
XAxes="{s:AxesBinding XAxes}"
YAxes="{s:AxesBinding YAxes}"
First example. The code of the axis:
var yAxis = new PolarYAxisViewModel {AutoRange = AutoRange.Never};
YAxes.Add(yAxis);
Changing the VisibleRange of the axis has no any effect on the visible range of the graph. It sets automatically in the very first time and remains the same.
Second example.
var yAxis = new PolarYAxisViewModel {AutoRange = AutoRange.Always};
YAxes.Add(yAxis);
Changing the data (using line series) again has no any effect on the visible range of the graph. Again, it sets automatically in the very first time and remains the same.
Any suggestion on how to fix it? Especially the first case is required. Thanks.

Hello,
I’m working with a polar chart and I’m having certain issues with the grid.
I’m trying to get a grid that covers all the surface, but I am not able to get it. I think it’s related to the Polar#Axis.
When I set a -200 margin on the Y axis, the grid lines separate and look like they are starting when I want, but they are not being draw outside the original circle.
When I set a -200 margin on the X axis, the outer circle goes outside the surface (red brush to watch it), but the Y axis does not reach the X axis and still inside the original circle.
Is there any way to get the desired grid?
I attach my code and a few images.
Thanks in advance.
<Grid Visibility="{Binding ShowPolarGrid, Converter={StaticResource BooleanToVisibilityConverter}}" >
<s:SciChartSurface Name="PolarGrid"
MaxFrameRate="24"
BorderBrush="Lime" BorderThickness="2">

</Grid>
