Hi!
I'm trying to plot data over a period of about 110s (sample rate 99Hz). The problem is that the XY-graph I'm using seems to collect only the last 100 samples for some reason. Am I doing something wrong or is this just a property that is changeble?

Hi Aleksi,
a graph does NOT collect any data - only a chart will do this! A graph only displays the data you feed by the wire. And in all that datatype mismatch you create plots containing just one X array element...
- You need to collect data on your own when using graphs.
- You may use the BuildGraph ExpressVI - or (to learn LabVIEW much better) you should use shift registers...

Thanks for quick reply.
However using "Create XY Graph" didn't solve my problem. The graph still shows only the latest samples (not all from the past). Could this have something to do with the DAQ assistant -properties?
Thank you in advance.

Sorry for not noticing that!
Now it's working!
