Hello dear Labviewers..
My waveform chart has a starting time at 3434102306 as shown on the picture below.
Here is a screenshot of my BD

How can i handle that problem ?. I want a minimum value to "-100" and the maximum value to "0"

The last time you asked about that VI, you wanted the actual time on the x axis. Now you want -100 to 0? How does that relate to time? Are you sure that you don't mean the Y axis? What have you changed about the chart's properties? Your previous VI displayed the current time correctly once you made the recomended change to waveform data type.

Hi Dennis
The chart was running too fast last time. It didn't match with the clock time. I asked about that last time.
The problem is solved now, but i cant change the minimum value and the maximum value in the properties now. There are 100 second between those values as i want, but i cant edit those crazy billion numbers
The reason why i need a "-100" value to minumum is because the data (samples) starts at the maximum side of the chart (right side), and therefore i will set the maximum value to "0".
I have only changed the type to "Floating point"

I don't know what you have changed or really what you want. The chart was never running more than once a second - at least with the VI you posted. If you changed the x axis to floating point, then of course the time is not going to be show correctly when you input a waveform data type. It includes timing information that you wanted, I thought. If you don't want timing, get rid of the waveform data type and just use the DBL like you had before.
I still don't understand the -100 to 0. You don't want time on the x axis? What is the -100 to 0 supposed to represent then? The data does not start on the right side of the chart when I run your previous VI so I don't understand your comment at all.
You are aware that the chart will just keep scrolling since you have not provided any mechanism to automatically stop the while loop.

Ok. I want the relative time which starts at 0:00:00 everytime i run the VI. The problem occurs also when i switch to the "relative time" in properties, it starts at 0:00:00, and then i plug the DAQ device and suddenly the time starts at 9543324:00:0, and i cant change that value.
