title: Set Excel chart axis title color and size in C#
body: <p>I am dynamically creating some Excel Chart datas/series and cannot set the Axis Title font color/size.</p>
  
  <p>I am able to add the Axis Titles with code similar to below:</p>
  
  <pre><code>//Gets the WorkSheet and ChartObject
  Worksheet DataSheet = (Worksheet)Template.Worksheets[1];
  Chart Graph = (DataSheet.ChartObjects(1) as ChartObject).Chart;
  
  //Gets the Axes
  Axis Xaxis = Graph.Axes(XlAxisType.xlCategory, XlAxisGroup.xlPrimary) as Axis;
  Axis Y1axis = Graph.Axes(XlAxisType.xlValue, XlAxisGroup.xlPrimary) as Axis;
  Axis Y2axis = Graph.Axes(XlAxisType.xlValue, XlAxisGroup.xlSecondary) as Axis;
  
  //Sets X-axis attributes
  Xaxis.TickLabels.Font.Size = 8;
  Xaxis.HasTitle = true;
  Xaxis.AxisTitle.Text = "Current (A)";
  
  //Sets Y-Primary Axis attributes
  Y1axis.TickLabels.Font.Size = 8;
  Y1axis.HasTitle = true;
  Y1axis.AxisTitle.Text = "Power (W)";
  
  //Sets Y-Secondary Axis attributes
  Y2axis.TickLabels.Font.Size = 8;
  Y2axis.HasTitle = true;
  Y2axis.AxisTitle.Text = "Voltage (V)";
  </code></pre>
  
  <p>But I can't figure out where the color, font size, bold, etc... attributes are.</p>
