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 |
