title: Multiple Series in Line chart in Winform using C#
body: <p>I am new in <code>Winform Application</code>. I am trying to implement a <code>line chart</code> which have  multiple <code>series</code> and have a <code>checkedListbox</code> to select the <code>particular series</code>.</p>
  
  <p><strong>Code:</strong></p>
  
  <pre><code>if (tbROI.SelectedTab == tbROI.TabPages["tbPageROIPoint"])
              {
                  //If all ROI TAB
                  myIndex = GetMyChartIndex(mSeries, chartPointROI); // 4 for Point ROI tab
  
                  m_PointDataCounter++;
                  if (m_PointDataCounter &gt; 15)
                  {
                      if (myIndex &gt; 5)
                      {
                          chartPointROI.Series[mSeries].Points.RemoveAt(0);
                          m_PointDataCounter--;
                      }
                  }
  
                  if (cbListPOI.GetItemChecked(ROIIndex))
                  {
                      chartPointROI.Series[mSeries].Points.AddXY(timestring, mData);
  
                      chartPointROI.ResetAutoValues();
                  }
              }
  </code></pre>
  
  <p>Using this code I am putting the data on the <code>chart control</code>. 
  The <code>X-axis</code> representing Time and <code>Y-axis</code> representing Data.</p>
  
  <p>Initailly when I select any item of <code>listbox</code> the series starts from left side, but after sometime if I start one more series it will also start from left side but I want to start that from the current time which is representing on X-axis. </p>
  
  <p>And when I stop any <code>series</code> after some time if I again start the same <code>series</code> I want to some gap in the series so that it can be clearly seen that series is been stopped.</p>
  
  <p>In my case the series always starts from left side. And if I stop any series and start that again It will continue where it stopped.</p>
  
  <p>Thanks in advance</p>
