What do you really want to do? What format is your data? What do you mean by "plot dynamic data"?
I'm going to "make up" answers to these three questions (which may be entirely wrong for your situation) and then give a completely different answer to the suggestions that have been made here. I assume:
- You are acquiring continuously-sampled data (say, from an A/D converter) at a fixed sampling rate (say 1KHz).
- You want to "play back" the data as though you were watching as it was being acquired, sort of like playing back tape-recorded data and looking at it on an oscilloscope.
- You may want to do some minimal processing during the playback, for example to display the average of 100 points at a time so you see 10 "new" points a second instead of 1000.
If this is the case, namely you want to see the signal evolving in time (as opposed to examining the entire signal "all at once in a single image", you would use a Chart to display the results (as this gives you the evolving image). When reading the data, you would mainly read the "data channel", using the "time channel" just to get the "dt" (time between samples) to set the X axis properties so it showed elapsed time (in milliseconds, seconds, minutes, hours, whatever is appropriate for your data). You'd present the Y data points one-at-a-time to the Chart (using For or While loops) with a Wait (ms) inside the loop to "clock" the display update as appropriate.
So that's another option if this is what you really intend. However, I agree with my colleagues that a Graph is more appropriate if you want "all-at-once" displays. However, if the actual time that the data was acquired (e.g. 11:45 am, 6-Jul-2016) isn't important, you can simply create a single Y array of data and not present X, but let it be "implicit" (scale it by setting the X Axis Properties appropriately).
