thank you..is there anyway to change the time and date on the graph?

Hi,

To my understanding LV take the system time only.

But if u are facing problem of the year 1900 then you can create waveform and add current time to it

Hi,

Check out the following ex.

[hafizzuddin]

this example graph do show the real present time and date. is it posible to have it done on the VI before?

Open the example finder and search for 'Chart'. Open the example called Real Time Chart. Do the same thing as in the example to program the chart to display the actual time. The example uses relative time but you can modify it to show absolute time.

p.s. Your case that reads the file is just silly. Absolutely no reason to read the entire file with every iteration of the loop. You are just wasting resources.

Put the read outside the loop. Or is you intention to give the user the ability to read a different file? An event structure would be better for that.
