Greetings,
I am a relativley newbie to Labview (5.0.1). Got a serious problem.
I have created a simple VI to collect voltages from 2 sources. I used the
Simple Analog Sample Single point Sub-VI (x2).One sample per second. I stuck
this in a For-loop and wrote the data to a file. I also bundled the outputs
from the sub-vi and outputed that to a Waveform Chart. It worked fine.
I modified that file to use Simple Analog Sample Multiple points (not multi-
waveforms). The data was bundled and output to a Waveform Chart. (no file this
time). I got a repeatable Application Exception Error (Win NT 4.0 workstation).
Using the trace function, I found the error occured as the data hit the bundle
function. I dropped the Sampl
e AI and used a random number generator, the error
still occured (as data hit the bundle functtion).
I started from scratch the next time (tonight). I used a for-loop, Simple AI
multipoint. One sample per second. Data indexed and then put into a bundle to
put into a waveform chart. It worked !! but all of the plots were in just one
of the five windows in the chart. I stopped the execution. I right clicked on
the chart and chose overlay/stack. BAM !! the exception came back.
What am I doing wrong ??!! Is it easy to fix?
You can look at the VI for yourself. Like I said it is very simple:

The file is called "Closed Loop DAQ.VI" and is 77k.
I really appreciate any insights you might have.
