RETAIN PLOTS IN XY GRAPH

[chravikumar]

Hi,

I know that plot points can be retained if i use an Express XY graph. But i have array of data coming from a while loop. I will be executing the while loop from time to time. I want the array to be plotted on XY graph and when i again run the while loop the second set of data should be appended to the graph. How can i do it. 

cheers

You can read the data via local varible from the Graph, then append the new data to it and write on the terminal.

Or you could store all data in an unititialized shift register on your while loop and append the new data. Initialize the shift register with the first call primitive.
