display_on_mixed_signal_graph

[kris69]

hello,

thank  you for the information concerning the global variables.

i have another question.

Why, in my affichage acquisition test.Vi, is the display of data logged (waveform) not the same as in the mixed signal graph

PS: global2.Vi is my global variable that enables me to transfer the data of my XY graph from Rampe.Vi to affichage acquisition test.Vi

thank you very much

Hello Kristof,

Could you give more info about which graphics are not the same? I don't really see the problem.

Thanks,

[kris69]

in fact when the data acquisition test.Vi runs, the "data logged" waveform displays a continuous signal.

The X scale origin is the time at which the run began.

When you look the mixed signal graph, you can see the signal who is coming from rampe.vi and the signal from the "data logged" waveform.

Why is the display of this last signal not the same on the mixed signal graph and the wave form "data logged"?

In fact the signal from rampe.vi is the control (consigne signal) that will pilot a oven and the data logged will be by example the temperature acquisition that normally will follow the consigne. But for this i need to use a PID (i haven't done yet). That's why i'd like that the display of the data logged waveform must be the same in the mixed signal graph

thank you

Hey Kris,

I know it a little bit late to reply but the problem come from the X-axis. The principe of Mixed signal graph is that you should have the same scale on the X-Axis and this is not your case !

Success for future.
