Re^4: Is it possible to create an interactive scale for palette in GNUplot?

Exactly what I was looking for. Thanks! I tried making it a variable based on the users input

$chart->set(cbrange => '[$x:$y]');
[download]

But it gives me an error "Column number Expected". Any ideas?

Your variables won't be interpolated inside single quotes. Use doubles `$chart->set(cbrange => "[$x:$y]");`	[reply] [d/l]
