I am using Telerik's RadCartessianChart but I assume the problem (and hopefully solution) is the same for any charting controls.

I have a class looking something like

C#
public class GenericData
{
     ObservableCollection<double> XValues { get; set; }
     ObservableCollection<double> YValues { get; set; }

     public GenericData()
     {
          XValues = new ObservableCollection<double>();
          YValues = new ObservableCollection<double>();
     }
}


This is how the data is provided to me so it would be great if I could just set the data context of the chart to the instance of the object of type GenericData and set the XValueBinding="XValues" and YValueBinding="YValues" but it doesn't work like that I am finding out.

Is there any way I can achieve this goal?

Otherwise the only solution I can come up with is creating a wrapper object that structures the data into a Collection of GenericDatum which contains a single XValue and YValue. I really do not want to do this because speed is an issue in this application and iterating through the GenericData to create a new Collection is going to impact the performance.

Not an expert, but I assume that its normal to have a KeyValuePair and specify what values should be used for x and y in the binding.

Normally I believe most people bind to a collection of objects which contain a single X and Y value. I am trying to do the opposite - bind to a single object that contains two collections, one of Xvalues and one of Yvalues.

People don't do that, or so it seems. They generally just create one collection with two properties, a key property and a value property, hence normally called a KeyValuePair, .NET even has an own function for it.

Yes. Sorry if I was unclear with how it is normally done vs how I am wanting to do it.

To put it another way, I would like to bind the Key (or XValues) to one collection of doubles and the value (or YValues) to a different collection of doubles. Is there any way to achieve that?

Yes, but I dont really think there is a way around it. If speed is what you are worried about take a look at this:

Its mainly about 3D but it will apply to 2D as well.
