it works if you take out the plot statements form:
if( RAS == 1 ){
<Complex code here>
}

Hi.
I'm working a new-to-me corner of the AB universe lately, and I'm
having an issue that I don't yet know a solution for. Perhaps someone
else has been here before and can point me in the right direction.
I've created a complex chart that requires alot of CPU to calculate and
draw.
Using _TRACE() I can see that the chart code is executing approximately
once per second. The effect of this is to tie up the CPU.
The nature of this chart is such that I only need to draw it once and I
am not interested in updating it a) on every tick, or b) every second.
IOW, I'd basically be satisfied to draw this chart once when I apply
the AFL to the pane. (Secondarily, I might want to add a manual
refresh button, but that's beside the point at the moment.)
I have tried to put the entire code in a Status() condition like so:
RequestTimedRefresh( 20, ) ; // trying to
reduce CPU load, but this does not stop the "regular" refresh
RAS = Status( "redrawaction" ) ; // 1 if a timed refresh, else 0
if( RAS == 1 ){
<Complex code here>
}
The goal here is to prevent any "automatic" refreshes, and allow me to
specify a (much less frequent) TimedRefresh.
What I observe to happen in this case is that the chart paints
(quickly) at the TimedRefresh frequency, then disappears (goes blank,
to the background color) until the next TimedRefresh.
So, I'm currently stuck at either seeing the chart and paying the price
for constant refreshes, or having a flashing/disappearing chart which
is useless (but cheap!).
Thus the question, in a nutshell:
How to Draw a Chart Just Once?
(and not have it disappear on you).
Thanks to anyone who can shed some light on this for me!
