Waveform chart format(X-axis)

[Amanda_Kay]

Hi, this might be a stupid question but I can't seem to figure it out. I want my x-axis to start at 0 and count in milliseconds up to 50(maybe like 5 ms intervals) with just a relative time.

Thank you

I also would like to be able to see how long the chart stayed at it's maximum value, etc.

Congratulations on getting LabVIEW 2017 installed and working.  I've not managed to successfully do this on my laptop yet (when I tried, it blew up MAX and it took almost a week of work to get the system back "the way it was", namely with 2016 installed and running properly).  So I regret I can't look at your code, but here are some ideas --

• I'm assuming you are plotting a Waveform, which has LabVIEW Time as part of the Cluster.
• If your data are in a Waveform, then you need to be sure the "dt" setting is correct for your sampling rate.  In particular, if you sample at 1KHz, dt = 0.001 (1 millisecond).
•  I recommend setting your Time Axis (X) to Autoscale.  You can manipulate it later if necessary.
• Set the Display Format for Time as Floating Point, with 1 or 2 digits of Precision.  It will then show you the time in seconds.
• If you want the time scale to be milliseconds, change the Multiplier on the Scale Property for Time from 1 to 1000.

Play a bit with Chart settings, and see what works for you.

Hi Amanda,

I want my x-axis to start at 0 and count in milliseconds up to 50(maybe like 5 ms intervals) with just a relative time.

Set the x axis scaling to whatever you like - switch off autoscaling as needed…

Why do all controls/indicators in the blockdiagram hide their label?

What's the purpose of a "wait for next millisecond" in a loop communicating with an external device 4 times per iteration?

Why do you need to build a cluster of two elements just to convert that cluster into an array? Have you heard of BuildArray before?

Why do you Reshape an 1D array of two elements into a 2D array of 1×2 elements? Have you heard of BuildArray before?

Why do you resist to take advices from people while still asking for more help?
