timing of chart

[pomplamoose]

Hello, i have a problem with timing on waveform chart, dont know exactly whether this problem had been solved already, but here it goes:

i have a waveform chart showing the voltage im sending to analog outout port, so to carry some tests i set a waveform generator and then i set the signal to the square wave with frq = 1 to see whether the signal changes once a second as it would normally do. yeah well it does change and seem to be ok, but the time runs 10 times (approximately ofc) faster than it does in reality. only when i pause the vi, i can see that the square signal with 1 Hz frequency is a REAL 1 Hz. but is there a way to show time as it really goes? and so that the chart would move not like it's having a seizure, but as a NORMAL graph would move 🙂 hope my description is sufficient, if any questions occur, dont hesitate to ask 🙂 thanks!

What have you set the dT to in the waveform?

You should be aware that a chart, by itself, has no timing except for a default of 1 second between samples. You must provide any other times by using a waveform type or specifying the dt by writing to the multiplier property.

thanks a lot! getting to know labview i come across properties of the simpliest things like charts for instance, that actually matter depending on the task. thanks again!
