title: Shinobi chart donut series: How to change drawDirection?
body: <p>I would like to change drawDirection property in donut chart</p>
  
  <p>Please see this: <a href="https://www.shinobicontrols.com/docs/ShinobiControls/ShinobiCharts/2.8.7/Standard/Normal/html/Classes/SChartDonutSeries.html" rel="nofollow noreferrer">https://www.shinobicontrols.com/docs/ShinobiControls/ShinobiCharts/2.8.7/Standard/Normal/html/Classes/SChartDonutSeries.html</a></p>
  
  <p>this is part of the code I am referring to:</p>
  
  <pre><code>typedef NS_ENUM(NSInteger, SChartRadialSeriesDrawDirection) {
      SChartRadialSeriesDrawDirectionAntiClockwise,
      SChartRadialSeriesDrawDirectionClockwise
  };
  
  @interface SChartDonutSeries : SChartRadialSeries
  #pragma mark -
  #pragma mark Drawing the series
  /** @name Drawing the series */
  
  /** The direction in which data is drawn around the centre of the plot.
  
   - SChartRadialSeriesDrawDirectionClockwise: Configures the direction in which the data is drawn around the center of the plot to be clockwise.
   - SChartRadialSeriesDrawDirectionAntiClockwise: Configures the direction in which the data is drawn around the center of the plot to be anticlockwise.
  
   This defaults to `SChartRadialSeriesDrawDirectionAntiClockwise`.
   */
  @property (nonatomic) SChartRadialSeriesDrawDirection drawDirection;
  @end
  </code></pre>
  
  <p>this is my code:</p>
  
  <pre><code>let donutSeries = SChartDonutSeries()
  donutSeries.drawDirection = SChartRadialSeriesDrawDirection.SChartRadialSeriesDrawDirectionClockwise
  </code></pre>
  
  <p>How can I do that in swift 3?</p>
