How can I plot a Waveform Graph with an x scale that is not time ??

[Oussama_Zaidi]

Hello Everyone

It seems something very oblivious and easy but some how I am really stocked.

I want to plot a waveform, but instead y= f(time) I want to y= f(x) which x is a distance and y is Force.

I want to plot the force in function of the distance instead of time.

Thank you in advance.

Just edit the label for "Time" to be something else.  It is just the default label because most of the time (no pun intended) time is the x-axis for people.

Hi Zaidi,

just change the axis labels to "distance" and "force"…

(When your x values aren't spaced equally you should consider using an XY graph.)

[Bob_Schor]

A Waveform Graph (as opposed to an XY Graph) is meant for plotting Waveforms, a LabVIEW data cluster construct that represents XY values assuming that the X Values are equally spaced and can be completely determined by knowing the initial X value (call it "x0") and the equal spacing (call it "dx"), while the Y values are represented by the array Y of all the values.  Two common Waveforms are "sampled data" (where X is Time, and the Waveform Cluster labels are t0, dt, and Y) and "FFT results" (where the "sampled data" are amplitude, phase, or power, and the X corresponds to the initial frequency f0 and frequency interval df).

As other posters have noted, you are free to change the X and Y labels on the Waveform Graph or Chart to suit the units you are actually using -- just be sure that you are using Y values measured at equally-spaced X intervals, and that you identify the starting X ("x0") and the X spacing ("dx") in the Cluster.

Sorry I tried what you suggest and other staff too (see picture).

But Nothing works.

I want measured signal in function of Actual position.

The maximum value of actual position is 1250, but in the graph I see more than 3000.

This is a picture of the signals.

So in the picture I see 3 displays.  Two are waveform graphs.  The 3rd is an XY graph?

Is the XY graph correct?  And if not, how is it wrong?

What is the logical connection between "actual position" and dt of the waveform?

If you really want help, attach the vi and some data. Truncated images are useless.
