Hi, apologies in advance for an almost 'do my work' question, but
I'm a bit stumped as to where to start with something.
I wish to draw a plot with North-South and East-West axes upon which is
drawn an incomplete grid of points. For each point I wish to have
a circle drawn which is filled with a colour indicating the strength
of the data point.
Problems with this:
(1) I want to label the axes with a minimum of fuss, so I'd like to
preserve their values (not 0->array size) from the start.
(2) How can I draw filled circles?
(3) How can I get the filled cirles to automatically scale according to their
value?
Mmm, not as clear as I wished. You see I had a program to use TRIANGULATE
and TRIGRID to remap my 2d array of data onto a large grid and then print that as
filled contours, however my data is strictly not from points, its
from a 'region', hence the filled circle alternate approach. The problem
is that I'm finding it very difficult to do, I basically can't get started.
Any advice?
I can't quite think of an approach for this.
E-mail and post please, my newserver does tend to pass out from excitment
now and again and, as this is work related, I'd rather not miss a post that
way.
Thanks.
