title: How to show the marker points in line graph using c#
body: <p>I am using <code>Line graph</code> in my application and is working fine. I tried to draw the marker points in line graph,but the marker points are not displaying.
  In line chart marker properties, I have chosen <code>markerSize</code> as 5,<code>markerStyle</code> as Circle,<code>MarkerColor</code> as blue.Refer my code below.</p>
  
  <pre><code> series1.Name = "Series1";
   series1.IsVisibleInLegend = false;
   series1.IsXValueIndexed = true;
   series1.XValueType = ChartValueType.Time;
   series1.YAxisType = AxisType.Primary;
   series1.ChartType = SeriesChartType.Line;
   this.chart1.Series.Add(series1);
  </code></pre>
