zero waveform array

[Custom]

My application acquires data and displays it on a waveform graph.

When I make a second run, the previous run's data is displayed on the plot (I want only the most-recent run to be displayed).  This behavior is not a problem if I close and then open the application before making the second run.

The displayed data is written to a waveform array indicator (for additional processing functionality).  I think I need to zero the waveform array data in the indicator to alway have a fresh plot.

What is the best/easiest way to do this?

TIA

Waveform graphs don't retain data. Do you possibly use a waveform chart?

With a chart, you could write an empty array to the "history data" property node at program start, or simply reset the chart to defaults using an invoke node.

Hey Custom,

Here is a VI that demonstrates the different behaviors between the waveform graph and the waveform chart. You can also turn on and off the chart history. It simply uses a property not with the history being changed. I hope this helps.

Here is a modified version that allows you to run continously.

Thank you Sam and Altenbeck.

Your responses were helpful!

I used the Invoke Node to reset to defaults .
