current time in the x-Axis

[Justus Jonas]

Hi everyone,

I have some problems putting a waveform together that shows the current time in the x-Axis.

I tried to do it with “timestamp” and “build waveform” but it didn’t work out. All I need is some values over the current time x-Axis. 

All it shows in my waveform is the time since 1904, like it always does!

Probably a silly question, but can anyone help me out, maybe with an example VI?

You should give the offset and multiplier to the property node for the chart.. here i have attached a sample vi

You could do it without any property node.

Just have a look at the attachment.

Hope this helps.

Thanks, for that one,

it is just wat I wanted, but in your example changes the current date to 1904 as soon as you fillin some y-values!

can you fix that?

did you select time and date in the time and date-control?

Hi,

You have the current time in the x-Axis. So far so good, but your Time stays in this one second you start the VI.

It was probably my fault, because I didn´t explain my problem good. What I need is an Waveform with some y-values (every second) and the running current time in the x-Axis. So that, for example, I can see at what time of the day a peak showed up.

I hope I made it clear !?!

Hi Becktho,

I´m such a thickhead, you are right.

Thanks for the help

Did you also set dt?

If I set some y-values, dt = 1 and x0 to current time, I get different times on the x-axis.

I attach a screenshot, that shows this.

yes, I set dt as 1. But I don´t get what you mean with the different times on the x-axis.

You can see the time increase (e.g. 14:01:00.000, 14:01:05.000, 14:01:10.000).
