Hi Teddy,

We tested the code and it appears to be working as expected. We also changed it a little bit so that it really adds 100 data points and still everything looks OK. Here is the full example (in C#):

private void Form1_Load(object sender, EventArgs e)
{
   Random rand = new Random();

   NLineSeries series = new NLineSeries();
   series.DataLabelStyle.Visible = false;

   NChart chart = nChartControl1.Charts[0];
   chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator = new NLinearScaleConfigurator();
   chart.Series.Add(series);

   for (int i = 0; i < 100; i++)
   {
      series.XValues.Add(i);
      series.Values.Add(Math.Sin(i * 0.08) * 3000 + rand.NextDouble() * 1000);
   }

   for (int i = 26; i < 75; i++)
   {
      series.BorderStyles[i] = new NStrokeStyle(Color.Red);
   }
}

The attached image shows the output. Maybe there is some difference in the series settings? Is shadow drawing enabled for the series?

Hi all,

I have a question regarding coloring specific parts of a NSmoothLine series. Let say I have entered 100 values in this series. I want to from index 0 to index 25 to be black, from index 26 to 75 to be red, and index 76 to index 100 to be black again. I have used code like this to color the middle portion red:

for i as integer=26 to 75

     DirectSeries.BorderStyles(i) = New NStrokeStyle(Color.Red)

     DirectSeries.XValues.Add(xvals(i))

     DirectSeries.Values.Add(zvals(i) * 1000)

end

NChartControl1.refresh()

My issue with this code is it does not turn the specified section red. It appears as if there is still the black line and under it I can see the red. But I want the line to be only black, then only red, then only black.

I can explain my issue more if need be. Does anybody have any ideas?
