Saving current graph data

[glskinner84]

the problem with my using a chart is the ability to change my timebase...with a graph, it works better for me.

[glskinner84]

Can I increase my buffer size? Or program it to stop the freeze once the buffer is almost full?

[glskinner84]

I tried the Finite samples but it kept giving me errors.

It's helpful when you tell us what the error is. My guess is that you need to remove the Start and Stop DAQmx nodes. These are not needed with Finite.

That worked...Thank you sir!

[James.M]

No problem! Let us know if you need more help. There are also plenty of tutorials out there for stuff like this.

Thanks are best given in the form of Kudos.

I actually do have a question....about filtering. If I bought a USB scope online somewhere, (to analyze and record the signals like I'm doing in my vi) would it have a software filter? The reason why I'm asking is because when I get to 20-100mV ranges, I have a lot of variation in my signal, whereas a scope does not.

[James.M]

A lot of the time devices like that will have their own built-in filtering. The general rule-of-thumb when acquiring data is to oversample and average down to your desired actual sample rate. An example of a device that does this is any voltmeter ever.

Do any of the fucntions in labview do this?

Should I just take a mean of the points and feed them to my graph?
