How can I change the x axis to something other than time?

[tavwtby]

I've searched and couldn't find an answer to this. I need to plot load vs cycle count, and I cannot figure out how to change the x-axis from time to cycle count. In other words, I want to read the load on the y axis, and I want the plot updated everytime a cycle occurs.

tavwtby,

You can change the name of the scale on the x-axis in the Scales tab of the Chart Properties Dialog Box (Right Click » Properties).  To have a plot update each time it recieves a new value, use a Waveform Chart (Controls » Graphs » Waveform Chart).  You can also change the Update Mode from Right-Click » Advanced » Update Mode.  See this link for more details:

1). When I want counts vs. amplitude, I think "Histogram". Investigate the Histogram PtByPt.vi. See below for a graph example.

2). You're in the wrong forum, belongs in LabVIEW.

PtByPt.vi s for plot discrete data in histogram graph.. i want to plot continuous data (x-axis being voltage) and y-axis being counts

Kriti,

Have you looked at something like this:
