    I have a polar plot depicting 0 – 360 degrees for the angle, and 0 – 90 degrees for the radius.

    1. The angles are shown counter-clockwise. How do i change
    this to clockwise? One post I read said this was impossible, (which is ridiculous), and
    suggested adding the data backwards and hacking the labels to match. How do I implement this workaround?

    2. The radii currently start at 0 in the center and increase to 90 on the edge. How do I reverse this to show 90 in the center, and 0 on the edge? The point of this is to represent objects within a hemisphere overhead (0 – 360 degrees being the azimuth of the object, and 0 – 90 degrees being the elevation from the horizon).

    Thanks!

    1- This is not possible.

     2-You can do this by turning off the AutoLabels, and provide your own labels.

    e.g.:

    chart.Axis(

    StandardAxis.Polar ).NumericScale.AutoLabels = false;

    chart.Axis(

    StandardAxis.Polar ).Labels.Add( “90” );

    chart.Axis(

    StandardAxis.Polar ).Labels.Add( “80” );

    chart.Axis(

    StandardAxis.Polar ).Labels.Add( “0” );

    Dear Andre,

    also in the last version of the Chart component is not possible to get a clockwise polar degree values?

    Is there any workaround???
