Re: Multiple Y axes with different scales

[thanos1983]

Hello Sarat1729,

Are you using a module, if so which one? Sample of code?

Not everyone can see you problem and try to help you from your point of view without sharing as much information as possible.

Update your question so can try to assist you as soon as possible. :)

Update: I found this sample of code from Perl-beginners GD::Graph::bars - multiple x-axis data sets, is this what you are looking for? If so you can modify the y-axis accordingly.

#!/usr/bin/perl
use strict;
use warnings;
use GD::Graph::mixed;

my @data = (
    ["1st","2nd","3rd","4th","5th","6th","7th", "8th", "9th"],
    [3, 4, 14, '', '', '', 7, 20, 15],
    ['', '', '', 5, 3, 1, 3, 4, 1],
    );

#sets 3,4 will overwrite second y label

my $my_graph = new GD::Graph::mixed( );
$my_graph->set(
    transparent => '0',
    x_label => 'X Label',
    y1_label => 'Y1 label',
    y2_label => 'Y2 label',
    title => 'Using two axes',
    y1_max_value => 40,
    y2_max_value => 8,
    y_tick_number => 8,
    y_label_skip => 2,
    long_ticks => 1,
    use_axis => [1,2,1,2],
    legend_placement => 'BR',
    x_labels_vertical => 1,
    x_label_position => 1/2,
    two_axes => 1,
    legend_marker_width => 100,
    l_margin => 10,
    b_margin => 10,
    r_margin => 20,
    t_margin => 10,
    show_values => 1,
    );

$my_graph->set_legend( 'X', 'XY', 'diff-X/XY', '95%XY');

my $gd = $my_graph->plot(\@data) or die $my_graph->error;

open(IMG, ">Sample.png") or die "$!\n";
binmode IMG;
print IMG $gd->png;
close IMG;

Looking forward to your update, BR.
