Resetting Analog Waveform to 0, not able to plot Graph in WPF application.

[SachinDV]

I have an AnalogWaveform object , where samples are appended and Precision time are being  set.With  AnalogWaveform object I'm able to plot the graph through data binding in WPF.

But when I set the AnalogWaveform to 0 i.e, new AnalogWaveform<double>(0);(Which I believe to clear the AnalogWaveform object) then graph is not plotting.

Any Idea on this issue?

Hi, 

Can you please concretize or attache some  screenshots? I didn't really understand what is the problem.

Thx.

I went ahead and created a simple mockup, binding a graph to a waveform object, using Append to modify it, and assigning a new waveform to clear it (attached).

Based on your initial description, I would guess that your code is missing the change notification for the property (line 17 in my example)? Using Append will modify the waveform object, and it will raise a change notification to the graph. For Clear, in order for the WPF binding system to see the change, it needs an INotifyPropertyChanged implementation (or a dependency property) in order to see the new value.
