multiple plots, timestamped chart

[mstlaurent]

I need some help...
I acquire data from several GPIB multimeters at a variable rate. I want to display the data on a multiple plots chart in LV6. I am able to timestamp a single data by wiring the data and a number of seconds into a bundle and then connecting the cluster to the chart.
But I'm not able to display several timestamped plots. Is it possible?
Thanks for your help, it is appreciated.

It sounds like you are currently using a graph rather than a chart
since you are using the cluster of (timestamp, delta, data). If
you build an array of these clusters, each will create a new plot
when wired to the graph. There are examples of the different data
types in the examples/general/graphs/gengraph.llb/waveform graph.vi.
The third from the bottom is the one I am describing.

If you
are really wanting to chart, meaning to add to the plots over
time and have the history and new data combined to make longer plots,
then you will probably want to start using the Waveform datatype
instead of the cluster. The waveform datatype was added in LV6, and
it allows you to build timestamped data very similar to what you are
doing. Additionally, it will work with charts, so if you wire an array
of waveforms to a chart, this may be what you are looking for.
