Multi waveform in one Graph

[Encoder in LAbview]

Dear Sir,

            I have a problemthat I am using DAQ-9172(9215 & 9263) and I am sampling two signal at same time one from Encoder and other from a sensor (1 pule revolution) and I want to display both in one graph I used many example from help some time it give error some time i don't see any signals and also this is a single shot but i want to see signals continously.  So help me.

Hope to hear a answer soon

Hi,

You can build an array of your signals and display it in Waveform Chart... Look at the attached VI...

Hi,

Did you try to use the probe tool, to see at which 'point' is the problem. Probably you have chosen a wrong channel for your data acquisition... I would suggest to probe on the error cluster and the output from the data acquisition. I hope this can be useful...

One more thing, it's better to put after the While Loop DAQmx Clear Task. Usually it's recommended (I've also forgotten to insert it 🙂 )
