how I can start a waveform with a fixed date/time

[vicens]

I'm trying to start my graph with a fixed date/time (00:00:00  21/06/2007), but It starts with 02:00:00 01/01/1904

How I can to solve this problem?

Thank you

Hi vicens,

this question occurs often in the forum, but I never had to deal with time scales before.
So I made a small example and it seems it's difficult to get proper x-scale labels on charts. With a XY-graph it's working nice... So maybe you can switch to use a XY-graph instead?

The other way is to use the chart's property node to set the time. This is explained in the shipping example called Real Time Chart.

Thanks GerdW,

I've a mixer between waveform graph and XY graph.

I needed to display values while running the time.

Thank you, again.

If you want your graph to display time on the x axis, you have to uncheck the Ignore Time Stamp option. You could also use a property node as I mentioned. You should also use the Get Date/Time in Seconds instead of a time stamp constant. Place this outside the while loop so you get the current time when the VI starts.
