please help on analog sig gen for 1.2 ms

[RavensFan]

Rescale your X axis.

Your duration is 2.4 ms  (1.2 msec high, 1.2 msec low).  Your X axis is set for 1e-5 which is 0.1 milliseconds.  You are only showing a portion of your high part of the waveform.

Yes I am aware that it is a scale issue. I do not scale it. It should have scaled it automatically and correctly. It autoscales properly for seconds duration, however, it does not autoscale correctly for the durations in ms. There is something that I have to intervene in the chart?

[RavensFan]

I guess I'm not clear on why you think something isn't working right.

Can you attach your latest VI you used to get those two screenshots?

[newbieeng]

I meant that autoscaling feature of the waveform graph does not scale proportional to each other on this vi as it is shown in the attached image. Please find the vi in the attachment.

Look at where you are doing your number of samples calculation.

You are using a fixed Fs of 1000 in order to calculate your number of samples.

What you really want to do is multiply your Sampling frequency by your duration in seconds in order to get #s.

Thank you very much Taki1999. It works. As you see, I leave it constant that's why I got trouble with it. I modified it.
