I have an application where i'm pulling AI data from a process, using a waveform output. At first i only was interested in (4) channels and everything was perfect, the X axis was in seconds, the trends represented the channels...i used the luster unbundle function to separate the channels.
The problem now is that i added and additional (4) channels making my total channel count now (8). The waveform chart no long works when i unbundle (8) channels of data. Why?
Basically what i have now is running the waveform straight to the chart, X axis is OLE time and looks bad.
Any help would be appreciated.

show your code example

For (4) channels this works like a champ. IF i add channels, to the DAQ and to the bundle (sorry i said unbundle earlier) it doesn't like that.

How you collect 8 channels?
Are you sure there presents all 8 channels?

The channels are captured via DAQmx READ.vi, i know they are collecting because i can wire a waveform chart to the output line and get a data on all line. The time aspect of it is not good though, i would rather use the t0 second counter but what is being displayed is the timestamp.

Show your broken code.
I get single point for each channel form DAQ? Or array of points (waveform)?

why youuse waveform for single element?

This is not helping...

Why not?
on chart you'll see last point only, without history.
And why you want draw clester of WF, not array if WF?
Take subarray of your data and send it to chart
