Question

I have a generic chart type which contains points as List<double>. How can I programatically change the axis label for each point with a custom label, i.e. use a string instead of the double value?

For example:

point1 = (1,5)
point2 = (2,10)
point3 = (3,25)

Instead of the x-axis displaying 1,2, and 3, substitute 1 for California, 2 for Arizona, 3 for New Mexico. Thank you.

EDIT: I want to make this change through C#, not using XAML.

 charting : PieSeries.ItemsSource >
   < controls : ObjectCollection >
       < local : ChartPointData Value ="1"
                             Label="Pete" />
       <local:ChartPointData Value="3"
                             Label="David" />
       <local:ChartPointData Value="9"
                             Label="Justin" />
       <local:ChartPointData Value="5"
                             Label="Shawn" />
       <local:ChartPointData Value="5"
                             Label="John" />
   </controls:ObjectCollection>
</charting:PieSeries.ItemsSource>

let me know if it helps…

edit:

The article describes that there should be a class like this

    public classChartPointData
   {
       public double Value { get; set; }
       public string Label { get; set; }
   }

so do not use a Point class do a class with double and string…
