Graph turns out to be empty.

I've attached my vi. The waveform graph turns out to be empty, despite there being changes in my output. 
Need help.

Thanks.

One issue I'm seeing is that you are sending two different messages at the same time (two GPIB Writes in parallel).  You should send the set command and then the querry command.  My guess is that you are often interrupting the querry, therefore the instrument is not sending anything back.  You may need a delay between the two GPIB writes as well.

You seem to have an allergy to straight lines! While the crooked ones behind other objects work just as well, they make it much more difficult to determine what is going on.

The stacked sequence structure can be replaced with an array of commands and a for loop. As crossrulz said, you may need a delay between some commands. Read the manual for your instrument.  You can use the error cluster to assure the order of execution and it  will let you know if you have any errors. If the Ramp Rate canot change while the program is running, that command should be outside the loop.

Turns out that it is showing an output. However, the time reading its showing in the x axis is completly wrong. Any idea, how I go about fixing that ? 

Thanks for helping so far.

Appreciate both of your help. 

Bytes of thanks in order.
