Important - need some help - multiple xy graph

[mido13]

Hi all

I attach in this messege a vi. it solve a diffrential equation. I works ok

but i need to find the responce (o/p) as the parameter (a) changes and has the values (20 - 10 - 5 - 2 - 1 - 0.5 - 0.2) on the same XY graph

Rely if sone one can solve the proplem. please do it.

thanks for concern

If you want to display the result on the graph as you change the values you need a loop around your code so it runs continuously. Note that this is NOT the same as the Run Continuously button in the toolbar. That starts/stops your VI each time and is only intended for debugging purposes. So, draw a while loop around your code, and wire a Boolean Stop button to the loop's condition terminal. You should place a small wait (say 20 msec or so) so you don't hog the CPU.

I was referring to a while loop, not a for-loop. A for loop will run a fixed number of times. A while loop will allow you to run it until you press the Stop button.
