in reply to Edited:Using Chart::Gnuplot to creat an interactive scale for palette?

> I hope my question is clear.

Nope, could you show some code?

Interactivity is a matter of speed and control.

Generally speaking if Chart::Gnuplot is fast enough you could trigger redraws from a gui (like tk)!

That's your question?

    Hi Rolf, So far I have a code that just plots the 2D contour plot. Here is a snippet, 
     my $chart = Chart::Gnuplot->new(
    output => "test1.png",
    title  => "3D plot",
    xlabel => 'x',
    ylabel => 'y',
);
$chart->set(pm3d => 'map');
$chart->set(palette => 'defined (0 0 0 1, 1 1 1 0, 2 1 0 0)');
$chart->set(dgrid3d => '385,385');

my $dataSet = Chart::Gnuplot::DataSet->new(
    points => \@array,
);

$chart->plot3d($dataSet);

    This does not have TK gui. But sounds like a good starting point.

      $chart->set(cbrange => '[-120:120]');

      See gnuplot page 181.

        Exactly what I was looking for. Thanks! I tried making it a variable based on the users input 
        $chart->set(cbrange => '[$x:$y]');

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