How do you input current time into a graph?

[ssteel]

I have data that will be inputed onto my computer via hardware but how do I get it to plot against time?

Cheers

Hi ssteel,

If you are using waveform then build waveform with input current time.

It is as follows in ex.

The Charts and Graphs always polt against time. The time base is just a factor of how often you are sampling. If you are sampling once per second, then the ticks on the X scale represent seconds.

Building on what Broken Arrow just said, once you have time on the x-axis,

you can right-click the axis, then go to  format.

You can then change the time to absolute or relative, as well as how the time is formatted.

Cheers, 

My input is numbers that im getting from I/O Assistant, how do I hook that up to the build waveform since it needs a brown connection rather than orange?

Are you getting one data point at a time, or an array of data points?

If you are getting an array, you can use Build Waveform in the Waveform palette.  Feed the array into Y, your delta T into dt, and your start time into T0.

You can also write an offset and multiplier (basically T0 and dt) into the X scale property nodes for the chart or graph.

Hello!!

Could i have a sample of the Ex.vi in version 8.5?

i couldn't open it in 8.6. Thanks! =D

Best Regards,

It is small enough you can easily recreate in LV 8.5.
