store data in chart

[Steve Gottschalk]

Trying simple app to read 1000 pts, find the mean, graph samples and add the mean to a second graph. VB.NET code generated by the DAQmx wizard. It uses AnalogWaveform(Of Double) to hold the data. (Nice that the wizard generates code with an obsolete class!). How do I put the mean values into a second Waveform graph and make it look like a strip chart recorder? Code snippet that find mean values and stores them in an array is shown below.

Dim m_count As Int16 = 0 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim acquiredData() As NationalInstruments.AnalogWaveform(Of Double) = DaqTaskComponent1.Read

WaveformGraph1.PlotWaveforms(acquiredData)

Dim mean As Double = Statistics.Mean(acquiredData(0).GetScaledData())

Gauge1.Value = mean

Dim MeanArray(0) As Double

MeanArray(m_count) = mean

m_count = +1

ReDim MeanArray(m_count) End Sub

The simple approach of MeanGraph.PlotWaveforms(MeanArray) fails with a long message.

Problem solved by using PlotY(ydata).
