Hi There,

I've plotted a bar series graph but as per my requirement I've to change the width of a individual bar (not all the bars) dynamically based on some criteria. Please let me know how this can be achieved.

Thanks, in advance.

Hi Naveen,

You can take a look at the range series, which allows you to draw rectangles with arbitrary bounds - the following code for example creates a bar chart, where the second bar has a slightly bigger width:

   NChart chart = nChartControl1.Charts[0];

   NRangeSeries rangeBar = new NRangeSeries();

   rangeBar.Values.Add(0);
   rangeBar.Values.Add(0);
   rangeBar.Values.Add(0);
   
   rangeBar.Y2Values.Add(10);
   rangeBar.Y2Values.Add(20);
   rangeBar.Y2Values.Add(30);

   rangeBar.UseXValues = true;

   for (int i = 0; i < rangeBar.Y2Values.Count; i++)
   {
    if (i == 1)
    {
     rangeBar.XValues.Add(i - 0.3);
     rangeBar.X2Values.Add(i + 0.3);
    }
    else
    {
     rangeBar.XValues.Add(i - 0.2);
     rangeBar.X2Values.Add(i + 0.2);
    }
   }

   chart.Series.Add(rangeBar);

Hope this helps - let us know if you have any questions...
