Hi All,

I have a bar chart with around 200 points. And I would like to highlight some points if they go down under certain value. I am using following line of code to find a bar:

int barIndex = in_barSeries.XValues.FindValue(Convert.ToDouble(dataset.Tables[0].Rows[index]["YValue"]));

This function is working fine. But my problem is, I have all the bars with nearly same values. So, if I do a FindValue, it doesn't always finds a right bar. It finds a bar that comes first in the series with the same value.

Please help me with this problem!!

Thanks,
Bhumi

Hi Bhumi,

In this case a simple loop trough the values will do the job - for example:

  private List<int> GetBarIndicesBelowValue(NBarSeries bar, double value)
  {
   NDataSeriesDouble values = bar.Values;
   int count = values.Count;
   List<int> barIndices = new List<int>();
   for (int i = 0; i < count; i++)
   {
    if ((double)values[i] < value)
    {
     barIndices.Add(i);
    }
   }

   return barIndices;
  }

returns a list of all bar indices that have a Y value below the specified one.
