Waveform

[WeberM]

Hello,

i've got a problem with appending signals.
i want to append new values to old values, but the "append signals" adds only one waveform.
the other ten waveforms doesn't exist after appending.

wheres the error?

Markus,

Wire the Appended Signals output from the VI to the output terminal of the case structure rather than the A input.

Hello,

actually I dont't know what might be going wrong. Please try with the attatched VI. It is a quick proove of concept example. I saved it as a LabVIEW 7.1 vi, if you are still working with 7.0 and cannot open it, just let me know.

How does it look like? Is it working?
regards

hello,

if i try the append signal function with one signal it works correct.
the problem is that i want to work with eleven signals.

OK, I agree.
THe append function seems only to work as expected if the Dynamic Data only contains one channel. have a look at the new example; it shows you how you will have to write your code.

Hi,

here s my suggestion (LV 7.1)

Hello,

i attached an example VI.

In this VI you can see that the single grph shows eleven Signals. to this point everythings alright.
when i want to append signalvalues to the end of the single graph (shown in "wrong graph") the result is wrong. there are eleven values in one waveform. and this waveform is appended.

one problem is also to have the time axis and not a axis which shows an index.

Hello Markus,
please also attatch the Demosignals.vi so I can examine your example.

Hello,

here is the demosignal.vi
