Chart::Clicker::Axis::DateTime - An X or Y Axis using DateTime VERSION
version 2.83 SYNOPSIS
my $axis = Chart::Clicker::Axis::DateTime->new; DESCRIPTION
A temporal Axis. Requires DateTime and DateTime::Set. Inherits from Axis, so check the methods there as well. Expects that times will be in unix format. ATTRIBUTES
format Set/Get the formatting string used to format the DateTime. See DateTime's strftime. time_zone Set/Get the time zone to use when creating DateTime objects! Accepts an object or a string ('America/Chicago'). METHODS

Chart::Clicker::Tutorial - A Tutorial for using Chart::Clicker VERSION
version 2.83 DESCRIPTION
This document aims to provide a tutorial for using Chart::Clicker. EXAMPLES
Simple chart from a single data source # grab the needed modules use Chart::Clicker; use Chart::Clicker::Data::Series; use Chart::Clicker::Data::DataSet; # build the chart my $chart = Chart::Clicker->new; # build the series (static here, will usually be supplied arrayrefs from elsewhere) my $series = Chart::Clicker::Data::Series->new( keys => [ 1,2,3,4,5 ], values => [ 52,74,52,82,14 ], ); # build the dataset my $dataset = Chart::Clicker::Data::DataSet->new( series => [ $series ], ); # add the dataset to the chart $chart->add_to_datasets($dataset); # write the chart to a file $chart->write_output('chart.png'); Simple chart from multiple data sources use Chart::Clicker; use Chart::Clicker::Data::Series; use Chart::Clicker::Data::DataSet; my $chart = Chart::Clicker->new; # start an array that will hold the series data my $series1 = Chart::Clicker::Data::Series->new( keys => [ 1,2,3,4,5 ], values => [ 52,74,52,82,14 ] ); my $series2 = Chart::Clicker::Data::Series->new( keys => [ 1,2,3,4,5 ], values => [ 34,67,89,45,67 ] ); # add the array of series data to the dataset my $dataset = Chart::Clicker::Data::DataSet->new( series => [ $series1, $series2 ] ); $chart->add_to_datasets($dataset); $chart->write_output('chart.png'); Simple chart with multiple data sources and custom colors use Chart::Clicker; use Chart::Clicker::Data::Series; use Chart::Clicker::Data::DataSet; # some new modules, these are only needed if you want to monkey with color changing use Graphics::Color::RGB; use Chart::Clicker::Drawing::ColorAllocator; # build the color allocator my $ca = Chart::Clicker::Drawing::ColorAllocator->new; # this hash is simply here to make things readable and cleaner, you can always call G::C::R inline my $red = Graphics::Color::RGB->new({ red => .75, green => 0, blue => 0, alpha => .8 }); my $green = Graphics::Color::RGB->new({ red => 0,green => .75, blue=> 0, alpha=> .8 }); my $blue = Graphics::Color::RGB->new({ red => 0, green => 0, blue => .75, alpha => .8 }), my $chart = Chart::Clicker->new; # Create an empty dataset that we can add to my $dataset = Chart::Clicker::Data::DataSet->new; $dataset->add_to_series(Chart::Clicker::Data::Series->new( keys => [ 1,2,3,4,5 ], values => [ 52,74,52,82,14 ] )); # add a color - note that the order of colors and the order of the # series must match, the first series will use the first color and so on # see contexts and axes for alternate ways of doing this $ca->add_to_colors($blue); $dataset->add_to_series(Chart::Clicker::Data::Series->new( keys => [ 1,2,3,4,5 ], values => [ 34,67,89,45,67 ] )); # add a second color $ca->add_to_colors($red); $dataset->add_to_series(Chart::Clicker::Data::Series->new( keys => [ 1,2,3,4,5 ], values => [ 11,22,33,44,55 ] )); # add a third color $ca->add_to_colors($green); $chart->add_to_datasets($dataset); # assign the color allocator to the chart $chart->color_allocator($ca); $chart->write_output('chart.png'); Example 4 : Simple chart with a different render type use Chart::Clicker; use Chart::Clicker::Data::Series; use Chart::Clicker::Data::DataSet; # add in the module of the renerer(s) you want to use use Chart::Clicker::Renderer::Area; my $chart = Chart::Clicker->new; my $series = Chart::Clicker::Data::Series->new( keys => [ 1,2,3,4,5 ], values => [ 52,74,52,82,14 ] ); my $dataset = Chart::Clicker::Data::DataSet->new( series => [ $series ] ); $chart->add_to_datasets($dataset); # build the renderer to use my $renderer = Chart::Clicker::Renderer::Area->new( opacity => .75, ); # assign the renderer to the default context $chart->set_renderer($renderer); $chart->write_output('chart.png'); Example 5 : Width and Height my $chart = Chart::Clicker->new(width => 1024, height => 768); Example 6 : PDF (or SVG or PS) my $chart = Chart::Clicker->new(format => 'pdf'); # Create the rest of your chart normally $chart->write_output('chart.pdf'); Example 7 : Hide the Legend and X-Axis my $chart = Chart::Clicker->new; # hide the legend $chart->legend->visible(0); # hide the X-Axis $chart->get_context('default')->domain_axis->hidden(1); Example 8 : Change the display format of the Y-Axis my $chart = Chart::Clicker->new; # a sprintf format to have 3 decimal places showing on the Y-Axis $chart->get_context('default')->range_axis->format('%.3f'); DISCLAIMER
