how can I make the x axis real time?

[relative0]

I would like to know how to make the X axis of a chart/Graph into realtime so that I can go in increments of seconds or milliseconds. How can I do this? I am getting some really funny stuff on my graphs and I notice the manual says that the "Time" label is just a default label. So I would like to know how to get the "real" time on my axis. Do you have any good ecamples?

Thanks,

Brian

If you use the waveform data type for your data then the X axis will reflect the time that the data was acquired.

Brian,
If you want to view time format on the axis, right click on the graph and select X Scale>>Formatting>>Absolute Time.
To get the current time on the axis, create a property node for the graph, and select XScale Offset and XScale Multiplier. Wire Get Date/Time In Seconds function to XScale Offset (if you have LV 7 you will have to use To DBL function between) and wire constant 1 to XScale Multiplier. (see the attachment)

Zvezdana,
I don't have LV 7, (I have 6.1) so that executable didn't come in. Also with what you mentioned won't I just get the time and date in seconds? what I want to get is the data ploted for the amount of time that the VI is running or that my Kodak Imaging board has been programmed to cycle within. I am going to attach some of the stuff I have been getting, I don't know if it is REAL TIME ,which I want, or if it is not.

Hi,

I agree with Zvezdana S.'s answer but there is a small problem with it. It is that he set the offset inside the while loop. That creates a problem since the waveform extends but the offset is also increasing. What you need is for the offset to remain constant so try setting it outside the while loop. I did that and works just fine. The example should make it clear.
