I put together a simple VI to show the effects of varying the
frequency of a Sine wave graphically. But I am not clear on two
counts :
1. The X-Axis scale : I want to see the patterns for a 10 second period
and then start fresh with a clear plot area. This is what the Scope
mode is supposed to do. But it does not happen so - it continuously
updates the X-Axis and only maintains the max-min difference as
10.
2. The while loop delay timing seems to affect the set frequency
of the Sine function. I thought irrespective of the update
rate, the sine function MUST produce the programmed frequency ??? What
am I missing ? ( To see what I mean just alter the while loop
delay and observe the time it takes to complete the plot of 1 Hz )
Thanks for any clarifications on above.
