2 y axes and one X

[Natig]

Hi everyone,

I have 2 different chart now.
I want to create a waveform chart that has 2 y axes and one X axes. I measure pressure and pressure difference with different devices but I want to see both values in same chart.

Methods that I have tried

in front panel

1. Mixed signal graph

2. A single waveform chart (duplicating scale and swap side)

In block diagram

1. Merge signals (I used merge signals to combine signals and connected it directly to mixed signal graph) nothing appeared in graph and there was no error as well.

2. Build arrays

So far none of them worked

I dont know what else I can try

Can some help me with this problem?

Thanks in advance for your time.

You need to place both in the same loop, then just duplicate the y scale and assign each plot to the right scale.

(I cannot see your VI unless you do a "save for previous (2020 or below)".)
