'Real' Time in Waveform Chart

[Tsaii]

Hi,

I've a waveform chart with 2 y-scales and 1 x-scale. I want to have relative time in my x-scale but the trouble is that values are stange: they're not in seconds, neither in minutes but in a kind of fast seconds... I get measures every 100 ms or 500 ms or 1s or 2s (this can change by user).

How can I have the time in this format 00:00:00 with 'real' seconds?

Thank you,

Hi,
you can't have real time with charts, a quasi-real-time behavior would be if you have equidistant measurement samples then you can use a property node with multiplier but still that's no real time.
If you want something more precise you should use xy-graphs...do a search on this in the forum and you will find plenty of information on this topic

PS: You will never get real time with a windows machine...

Actually, what you want to do is pretty simple. The default multiplier for the chart is 1 (right click>Properties>Scales). Just change it to be .1 to match the loop time (100 msec = .1 sec). You can also do this with a property node. Look at the shipping example called Real-Time Chart.

Yes! It's that, Dennis! Thank you very much. My explanations weren't very clear ('real-time' isn't the expression I'd have used) but finally, you've understood me, congratulations! Thanx to Mishi too, for taking time to answer...
