RE: Setting colour on a multi-plot indicator

Lionel:

I am not able to give a specific estimate at this time.  I do know that in
the past when we have added functionality that degraded performance (no
matter how small) we have received numerous complaints.  You are right in
your statement that all changes degrade performance to some degree.  I am
not willing, however, to simply add tons of functionality at the expense of
performance and tell all of our customers that the only solution is to buy a
faster machine.  My goal is to add functionality, minimize the performance
degradation and hope that we do not overwhelm the existing hardware of our
average customer.

PD Manager:
This answer is a platitude; almost all, if not all, the subscribers are
aware that more features can mean slower performance. You could have added
that this would also make the program larger. With the current speed of 800
Mhz to over 1 Ghz, a minor slow down in performance speed is tolerable. Just
how much degradation do you estimate?
