[Gnuplot-py-users] labels into plot

[tony <t.v...@in...>]

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
