title: Changing the orientation of polar chart (From clockwise to anticlockwise)
body: <p>I have a code that could plot multiple polar chart series with <em>Magnitude (in value) <strong>vs</strong> Phase (in degree)</em>. The provided code is shortened to plot a single series, <strong>S(1,1)</strong>. </p>
  
  <pre><code>Chart1.ChartAreas("ChartArea1").AxisX.Minimum = 0                                        
  Chart1.ChartAreas("ChartArea1").AxisX.Maximum = 360                                  
  Chart1.ChartAreas("ChartArea1").AxisX.Interval = 45                                        
  Chart1.ChartAreas("ChartArea1").AxisX.Crossing = 90    'To change the X axis starting point                                 
  Chart1.ChartAreas("ChartArea1").AxisX.Title = "Magnitude in value"                                        
  Chart1.ChartAreas("ChartArea1").AxisY.Minimum = 0                                        
  Chart1.ChartAreas("ChartArea1").AxisY.Maximum = 1.2                                        
  Chart1.ChartAreas("ChartArea1").AxisY.Interval = 0.2                                        
  Chart1.ChartAreas("ChartArea1").AxisY.LabelStyle.Format = "{0:0.#}"                                        
  Chart1.ChartAreas("ChartArea1").AxisY.Title = "Phase in degree"
  Chart1.Series.Add("S(1,1)")
  Chart1.Series("S(1,1)").BorderWidth = 2
  Chart1.Series("S(1,1)").Points.DataBindXY(para1, para2)    'para1 is a Double array containing the phase in degree and para2 is a Double array containing the Magnitude in value
  Chart1.Series("S(1,1)").ChartType = DataVisualization.Charting.SeriesChartType.Polar

  <p>It works fine. However, the orientation of the plot is in clockwise direction, as shown below. </p>

  <p>I was trying to change the orientation of this plot to anticlockwise direction with 90 degrees on the top and 270 degrees on the bottom. All I could do is change the X-axis starting point. I checked in a forum on <a href="https://social.msdn.microsoft.com/Forums/vstudio/en-US/644cb066-3501-417e-8610-6e3340fe6a95/how-to-change-polar-chart-orientation?forum=MSWinWebChart" rel="nofollow noreferrer">how to change the orientation of the plot</a>, but it only mentions on how to change the phase values to <strong>360 - original value</strong> and change the X axis labels. That does not help in my case, as I wanted to check datapoints by adding markers and it would show wrong values.</p>
  
  <p>Any help would be appreciated!!!</p>
