MS Charts: Different colors on label values

Question

Is their any possible way to get different colors on each X-Axis value of a radar chart?

Already tried custom labels, but it didn't work.

Any help will be much appreciated.

Answer 1

There are neither Properties nor CustomAttributes to achieve this for AxisLabels.

But CustomLabels will do the job nicely.

Here is an example that adds a CustumLabel for each DataPoint in a Series and gives it a random color:

Set up the data:

Random rnd = new Random(0);
List<Color> colors = new List<Color>() { Color.Red, Color.Firebrick, Color.Gold,
    Color.DeepPink, Color.Azure, Color.IndianRed, Color.ForestGreen };

ChartArea ca = chart.ChartAreas[0];

Series s = chart.Series[0];

for (int i = 1; i < 7; i++)
{
    s.Points.AddXY(i, i+ rnd.Next(20 - i));
}

Now add CustomLabels:

foreach (var dp in s.Points)
{
    CustomLabel cl = new CustomLabel();
    cl.FromPosition = dp.XValue;
    cl.ToPosition = dp.XValue ;
    cl.Text = dp.YValues[0]+ "$";
    cl.ForeColor = colors[rnd.Next(colors.Count)];

    ca.AxisX.CustomLabels.Add(cl);
}

Note that for ChartType Radar this is rather simple; for most other types getting the FromPosition and ToPosition is rather tricky: There you need to calculate (usually) the center between two points..
