Changing color between points in a series

[Agrilink]

Hi,

Is it possible to manually change the color between points AFTER adding a series?

I know you can do it when adding a series, however I want to set the color between each point in a line series after the series has been created, ie. loop through each series on the chart, and set the color between each point.

Is this possible?

Thanks in advance.

Hi Agrilink,

Yes, you have 2 options to achieve that:

1. Using one of Add method overloads which allow a color for each series point.
2. Directly looping through all series points and accessing its ValueColor property:

Code: Select all

      for (int i = 0; i < tChart1.Series.Count; i++)
			{
        for (int j = 0; j < tChart1[j].Count; j++)
        {
          tChart1[i].ValueColor[j]=Color.FromArgb(i,j,0);
        }			 
			}

Regarding option 2, according to the help ValueColor is a method requiring a point index and returns the color, not a property?

The code provided throws a compile error.

Thanks.

Hi Agrilink,

Yes, sorry, you should use:

Code: Select all

          tChart1[i].Colors[j] = Color.FromArgb(r, g, b);

Excellent. Thanks Narcis.
