title: C#: System.Windows.Forms.DataVisualization.Charting.Chart Set Line Size
body: <p>This is probably a really simple question but I am having a lot of trouble trying to figure out which property sets the line size on the <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.datavisualization.charting.chart.aspx"><strong>Chart</strong></a> or <a href="http://msdn.microsoft.com/en-us/library/system.web.ui.datavisualization.charting.series.aspx"><strong>Series</strong></a> class. The line is really narrow and hard to see.</p>
  
  <p>How do I set the <strong>line size</strong> for my <strong>FastLine</strong> chart?</p>
  
  <pre><code>Series set1 = new Series();
  for (int i = 0; i &lt; 10; i++) 
  {
       set1.Points.addY(x);
  }
  set1.ChartType = SeriesChartType.FastLine;
  set1.Color = Color.Green;
  chart1.Series.Add(set1);
  chart1.Invalidate();
  </code></pre>
