Inverting a plotting signal

I am plotting a signal on Waveform Chart, and I have the Y-axis scale minimum of -5 and maximum of +5, but inverted.  In other words, I have -5 above the 0 axis, and +5 below the 0 axis.  I want to also invert whatever signal that is plotting on that waveform chart, such that positve amplitude of the signal is actually plotting below the 0-axis. 

 

My question is how do I invert the plotting signal.  Is there a specific function in LabView that I can use to invert the signal right before being plotted on the Waveform chart?

 

I would appreciate any suggestion.

Regards

Hi, Tebefia,

 

There is a checkbox of invert in the scale property of the waveform graph.

Does it relate to your question?

Hi Tebefia,

 

- you can invert the Y scale as you already did by setting the max value as range.start and min value as range.end…

- you can use the checkmark as already told

- you can use the simple, but effective Negate function

- you could swap the wires on your DAQ AI input…

Best regards,
GerdW
