Plotting data to waveform graph continuously

[ASJ]

I have trouble with plotting data to waveform graph. My measurement device sends data in periods/cycles. I have managed to plot  data from one cycle, but when new cycle is read and plotted to graph the old data disappears. I would like to draw a plot that continues the old data. I have tried shift registers,  property node with no luck

Sounds like you need to increase the number of scans!

Are you writing to disk before graphing?

Post code or jpg of you code.

It makes it easier to understand problem

hi there

use a chart - type display instead of a graph - type. a chart appends the new data to the old data and displays the whole history of the data. see the LabVIEW "VI, function and how-to" online documentation and look at "Charts & Graphs"->"Charts".
