real time intensity graphs

Hi,
Can somone tell me if it is possible to make intensity plots real time.
I am currently
filling a 256 by 256 array one row at a time with data from a counter. I
would like to
plot each row as it comes out without replotting any old rows nor any new
rows of the
array currently empty of data. Using the command PlotIntensity forces me
to replot
the entire 256 by 256 array each time which tremendously slows down the program.
If anyone can help this would be much appreciated

thanks

Hi Ken,

I'm very sorry I cannot help you with your problem. However I do know someone
who may be able to help. I'm too struggling with the plotintensity function.
I'm finding it difficult to define the ColourMapArray. Can you help please!!

I solved this problem rather nicely by using a canvas and the CanvasScroll
function. You can draw line or blocks of color (after having scaled them
properly, but that is easy) on the right side and then scroll to the left by
the same amount of pixel.

what you want to do.
