reset strip recorder on each run

[AllanNish]

strip chart using waveform graph in labview. how can I reset the x-axis display to time =0 every time I run the program?

[RavensFan]

I'm confused.  Waveform Graphs do not have a "strip recorder" mode.

Are you talking about a Waveform Chart?

What is the datatype you have wired to the graph?

Attach your VI.

[AllanNish]

I'm taking the waveform from a USB-6251. Yes, waveform chart in the strip recorder mode. 

I'm not in my lab right now, but I will, if what I'm asking doesn't make sense.

Thanks for your reply .

Try either of these techniques.

The Reinit to Default is an invoke node.

The datatype may affect how they work, particular for the empty array for the history data property node.

[AllanNish]

I'm not sure if I have this correctly wired with the node that you sent, but it's not resetting the x-axis. Here is the vi.

Hi Allan,

1. You should ReInit before the loop, but not inside with each iteration.

2. You are using those DDT wires: this can introduce a lot of "side effects". Usually you are recommended not to use ExpressVIs and DDT wires…

3. You are reading "1 sample on demand" so do you expect any useful result from your filter?

One step to less DDT wires:

[AllanNish]

This is a dumb question, but how does one create the initialize strip recorder node? (does one right click on the wire?)

It almost works except for the initialize step.

[RavensFan]

Right click on the Waveform chart terminal.  You have two choices, create property node and create invoke node.  In this case, the reinitialize is a "method" so you use Create Invoke Node.

[AllanNish]

The waveform chart is still not resetting. I'm not sure if I've invoked the node correctly. (The chart will reset if I close the vi and reopen it. But it won't reset if I rerun) (Fortunately, rerunning will reset the time stamp on the measurement file).
