How to Plot XY Data WPF

[rle2]

Plotting on winform is quite simple but I am trying to move to wpf and encountering some issues. How can I plot XY graph with Graph control? In the example below, I just want to plot the signal vs t.  I can find some example for plotting but none is for xy plot

            int Fs = 1000;
            double T = 1.000 / Fs;
            int L = 2000;
            double[] t = new double[2000];
            double[] signal = new double[2000];

            for (int i = 0; i < L; i++)
            {
                t[i] = i * T;
                signal[i] = Math.Sin(2 * 3.14 * 50 * t[i]);
            }

                Graph1.DataSource = signal;

Hello rle 2,

Are you using Measurement Studio? Have you seen the documentation on graphing using WPF?

To plot XY data, you just need to provide the graph with a type that includes both X and Y values, such as a Point[] (or possibly a ChartCollection <double,double>😞

...
Point[] points= new Point[2000];

for (int i = 0; i < L; i++)
{
    points[i].X = i * T;
    points[i].Y = Math.Sin( 2 * 3.14 * 50 * points[i].X );
}

Graph1.DataSource = points;

You may also want to look at the "XYPlotting" example that comes installed with Measurement Studio.
