Performing Batch Updates

You can perform batch updates without refreshing the chart after each change by entering your code inside the BeginUpdate()/EndUpdate() methods like the following:

C1Chart1.BeginUpdate()
   ' change or format the chart, add data etc.
   ...
   C1Chart1.EndUpdate()

c1Chart1.BeginUpdate();
  //change or format the chart, add data etc.
   ...
   c1Chart1.EndUpdate();
