Plotting AnalogWaveform on the Waveformgraph with PlotWaveforms method using Measurement Studio 2013 in .Net

Question

I am using Measurement Studio 2013 with VS 2012.

I am fetching data from NI PXI 5122 which I want to plot on the graph. I can clearly see the records when printed in console or even on the gridview but I am unable to plot it on the WaveformGraph. Here is my code:

    static void PlotWaveformsOnGraph(AnalogWaveformCollection<double> waveforms)
     {       
           List<AnalogWaveform<double>> waveformList = new List <AnalogWaveform<double>>(waveforms);
           MainWindow main = new MainWindow();
           main.waveformGraph.PlotWaveforms(waveformList.ToArray());
     }

there is no error in the above code, also the data is present in WaveformList but not plotting on the graph.

Can you explain what the problem is? Do you get an error message? — Håken Lid, Jul 14 '15 at 22:07
@HåkenLid - The problem here is I am not able to see the values plotted on the WaveformGraph. The graph is clear wit no plots. — Priyanka Chidanand Walake, Jul 15 '15 at 23:05

Are you creating a MainWindow instance dynamically in your PlotWaveformsOnGraph method because you cannot reach the waveformGraph object from context of the method? If so, you might consider the following:

Passing the waveformGraph object to which you plot your waveforms as a parameter to your PlotWaveformsOnGraph method. This way, you can access the PlotWaveformsAppend method on the waveformGraph from within your static method.

This might look like:

static void PlotWaveformsOnGraph(AnalogWaveformCollection<double> waveforms,
   WaveformGraph graph)
{
    var waveformList = new List<AnalogWaveform<double>>(waveforms);
    graph.PlotWaveforms(waveformList.ToArray());
}

Remove the static keyword from the PlotWaveformsOnGraph method. Assuming PlotWaveformsOnGraph is a member of your MainWindow class, and your window has a WaveformGraph control on it, you can access the waveformGraph from within your method. Do you have a specific reason for making this method static?

It looks like more progress on this issue is being made here.
