I cannot get SCILinearGradientBrushStyle working on a donut chart. Only radial gradients work

Here is my code sample:

let segment = SCIPieSegment()
segment.fillStyle = SCILinearGradientBrushStyle(colorCodeStart: 0xff007aff, finish: 0x4D007aff, direction: .horizontal)
segment.value = 100.0
segment.title = "Segment"
donutSeries.segments.add(segment)

The segment just renders a flat color

Hi

I am developing a Xamarin iOS application and I’m using a SCIPieChartSurface. I can create the chart and set its values, but it is not possible to auto-update the donut with new data.
I am trying to update the value by doing:

myDonut.MyPieSegment.Value = newValue;

But nothing happends…

I heard it was a bug in the API for Android a month ago, is this similar? Or am I doing something wrong?
Thanks in advance!

Hi
Is there a way to just change the values of the pie segments so it get updated on the donut chart.
If I remove and add the pie segments again it works, is this the correct way?

Also I can’t find any documentation around the donut for android/xamarin

Is there any way to configure the padding on a pie/donut chart? I’m trying to squeeze a few in a dashboard type arrangement and there’s about 100px of padding either side of the doughnut itself that’s taking up a lot of space:

<s:SciChartDonutSurface Grid.Column="0"
                    SegmentSpacing="4"
                    ItemsSource="{Binding DonutModels}"
                    ShowLegend="False"
                    ShowOutsideLabel="False"
                    BorderBrush="Black" BorderThickness="1"
                    HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
                    MinHeight="300" MinWidth="300" AllowClickSelection="False" AllowMultiSelect="False"
                    ShowTooltip="False">
<s:SciChartDonutSurface.ItemTemplate>
    <DataTemplate DataType="gauge:DonutSegmentViewModel">
        <s:DonutSegment Fill="{Binding Fill, Mode=TwoWay}" 
                        IsSelected="{Binding IsSelected, Mode=TwoWay}"
                        SegmentValue="{Binding Value, Mode=TwoWay}" 
                        Text="{Binding Name, Mode=TwoWay}" 
                        Stroke="{Binding Stroke, Mode=TwoWay}" 
                        StrokeThickness="{Binding StrokeThickness, Mode=TwoWay}"/>
    </DataTemplate>
