Re^2: Draw chart

Hi, below is my dataset. Dates is my x axis and other record is y axis. if you run you can see that y axis numbers are duplicated (two times 0, two times 1).

Ok, those duplicates were actually `Chart::Mountain` trying to be helpful as it had inserted halfticks into the Y axis to try and improve the overall readability of the graph. At some point in your travels, you unfortunately brought yourself undone by setting `precision => 0`, which caused those halfticks to round down, 4.5 to 4, 3.5 to 3 etc... What you should be using is `'integer_ticks_only' => 1,`. I don't know what `$popname` was sposed to do, so I removed it. And it makes far more sense to declare the graph options in a single list rather than some up top in a separate hash, and others hidden lower down... #!/usr/bin/perl use strict; use warnings; use Chart::Mountain; my $filename = $ARGV[0]; my $g = Chart::Mountain->new(1000,500); $g->add_datafile( "$filename", 'set' ); $g->set ( 'title' => 'Video Server Play Daily Hourly + Report', 'grid_lines' => 'true', 'y_label' => 'Numero Streams', 'x_label' => 'Dates', 'include_zero' => 1, 'x_ticks' => 'vertical', 'tick_label_font' => (GD::Font->Giant), 'title_font' => (GD::Font->Giant), 'colors' => {'dataset0' => [0,255,0]}, 'integer_ticks_only' => 1, 'misc' => [0,0,0], ); $g->jpeg ("graph.jpg"); [download] Data.txt: 29/04/2010-00.00 29/04/2010-00.30 29/04/2010-01.00 29/04/2010-01.30 29 +/04/2010-02.00 29/04/2010-02.30 29/04/2010-03.00 29/04/2010-03.30 29/ +04/2010-04.00 29/04/2010-04.30 29/04/2010-05.00 29/04/2010-05.30 29/0 +4/2010-06.00 29/04/2010-06.30 29/04/2010-07.00 29/04/2010-07.30 29/04 +/2010-08.00 29/04/2010-08.30 29/04/2010-09.00 29/04/2010-09.30 29/04/ +2010-10.00 29/04/2010-10.30 29/04/2010-11.00 29/04/2010-11.30 29/04/2 +010-12.00 29/04/2010-12.30 29/04/2010-13.00 29/04/2010-13.30 29/04/20 +10-14.00 29/04/2010-14.30 29/04/2010-15.00 29/04/2010-15.30 29/04/201 +0-16.00 29/04/2010-16.30 29/04/2010-17.00 29/04/2010-17.30 29/04/2010 +-18.00 29/04/2010-18.30 29/04/2010-19.00 29/04/2010-19.30 29/04/2010- +20.00 29/04/2010-20.30 29/04/2010-21.00 29/04/2010-21.30 29/04/2010-2 +2.00 29/04/2010-22.30 29/04/2010-23.00 29/04/2010-23.30 2 3 1 1 2 2 1 2 2 3 2 1 1 1 1 4 3 3 2 1 2 3 1 1 2 2 1 2 2 3 2 1 1 1 1 +4 3 3 2 1 2 3 1 1 2 2 1 2 [download]	[reply] [d/l] [select]

well, you're right if in your dataset Y axis is composed by little numbers as 1-3-2-4-5-6. if we got in Y axis number like 100-200-300, output jpeg is unreadable because of this option 'integer_ticks_only' => 1,. many thanks for you help	[reply]
