Questions

Hi, Andrew,

We are looking for functional and effective charts and Scichart looks realy awesome. But polar chart with X axis started at the bottom is what we really need.

I’ve read about workaround with LayoutTransform, but, as you mentioned, it could be difficult to make it work really nicely with annotations, axes etc. And it is even harder and risky to implement it on the side. That is the little step that keeps us from opt for the Scichart.

I am still not your customer, but I really wish to be )

I need 0-360 fix scale as in the picture bellow, I should not rotate.

**For the desired output:

 1. Create a custom Tick Provider.**

>         public class DoubleTickProvider : TickProvider<double>
>         {
>             public override IList<double> GetMinorTicks(IAxisParams axis)
>             {
>                 return GenerateTicks((DoubleRange)axis.VisibleRange, (double)axis.MinorDelta);
>             }
>     
>             private static double[] GenerateTicks(DoubleRange tickRange, double delta)
>             {
>                 var ticks = Enumerable.Range(0, 360).Where(x => x % 45 == 0 || x == 360).Select(t => (double)t).ToList();
>                 return ticks.ToArray();
>             }
>     
>             public override IList<double> GetMajorTicks(IAxisParams axis)
>             {
>                 return GenerateTicks((DoubleRange)axis.VisibleRange, (double)axis.MajorDelta);
>             }
>         }

 **2. Declare the provider.**

>  <UserControl.Resources>
>     <viewModels:DoubleTickProvider x:Key="CustomTickProvider " /> </UserControl.Resources>

 **3. Use the provider and set the rotation angle.**

>     <s:SciChartSurface.XAxis>
>                         <s:PolarXAxis
>                             x:Name="xAxis"
>                             FlipCoordinates="False"
>                             RotationAngle="90"
>                             TickProvider="{StaticResource 'CustomTickProvider '}" />
>                     </s:SciChartSurface.XAxis>
