title: C# EPPLUS setting the angle of the chart's X axis tick labels
body: <p>Is there a way to set the angle alignment of the axis tick labels in a chart using EPPLUS? I'm generating eChartType.XYScatterLinesNoMarkers charts and my X axis (having a lot of tick labels) looks very cluttered.</p>
  
  <p>How the chart looks currently with a cluttered X axis:
  <a href="http://i.stack.imgur.com/aWNfj.png" rel="nofollow">X axis horizontal alignment</a></p>
  
  <p>How I would like the chart to look:
  <a href="http://i.stack.imgur.com/Lav5W.png" rel="nofollow">X axis 45 degree alignment</a></p>
  
  <p>If it's not possible to set the angle, is it possible to set the labels' orientation to a vertical orientation; i.e. 90°?</p>
  
  <pre><code>var chart = chartWorksheet.Drawings.AddChart(entry.Key, eChartType.XYScatterLinesNoMarkers);
                      chart.XAxis.MaxValue = businessDayDate.ToOADate();
                      chart.XAxis.MinValue = businessDayDate.AddDays(chartDayThreshold * -1).ToOADate();
                      chart.XAxis.MajorUnit = 20;
  </code></pre>
  
  <p>I'm able to edit the min, max, major/minor units of the axis but not the alignment of the labels.</p>
