Ok, i didn't do a good job of explaining myself. I've also done a
little bit of research. Ultimately i'm looking to produce a contour
plot (usually you can use the contour function in direct graphics or
the idlgrcontour object). The idea is to produce this plot as data
arrives, arriving approximately one profile every 2.5 seconds. Its a
slow inefficient way to re-calculate the contour so in direct graphics
i drew one profile at a time onto a plot using the plots command and
scaling the colours to the data values (so a series of these profiles
produces a contour plot however it is drawn on the fly).

So now i am trying to do something similar with object graphics. I
tried doing it by updating my data to the idlgrcontour object using
contour->setproperty,data_values=new_data as new data arrives. The
problem with this is as the new_data array increases in size the time
taken to re-calculate the contour also increases, eventually it becomes
far to slow. I'm looking for a way to do this in a more efficicent way.

I hope this is clearer

many thanks
