Acquiring of two voltages on two distinct waveform charts

[fparisi]

I have simply to acquire two voltages and display it on two distinct waverform charts, by using LabVIEW 7.1 and NI-DAQmx 7.5 (bundled with the USB 6008).

I build the VI express with DAQ Assistant but it doesn't work, I can't view the two voltages:

 

By highlighting execution I can see the flow but seems that it can't go out the while loop

At work (with LabVIEW 8.6 and latest NI-DAQmx) all works fine.

Any hint?

Thanks in advance

Of course you can't see the signals. You've got the charts outside the while loop. NOTHING will get written to the chart until the loop finishes.

Ok, but if I replace the stop button with a boolean switch works fine also with charts outside while loop...

I'm a bit confused

Now you've confused me. A stop button is a Boolean switch. You wouldn't happen to be using the run continuous mode on the toolbar would you? If you are, that is not something to be used for normal operation.
