Thanks Michael
I can now place a label on the graph, but what I really want to do is
have the label be a variable that is updated every few seconds.
I've tried to include this in
g('set label 1 sprintf("%f",inc) at 2,2')
where inc is the variable but in a While loop I keep getting an
undefined variable error, even though the variable is defined in the
line above. I've seen this done in other scripts, but not necessarily in
a while loop - is that the problem?
Thanks
Tony
