Chart::Scientific is a Perl module that can generate simple 2-D scientific plots with logging, errbars, etc. SYNOPSIS Procedural interface use Chart::Scientific qw/make_plot/; make_plot ( x_data => @x_values, y_data => @yvalues ); The subroutine make_plot creates a Chart::Scientific object passing along every argument it was given. See OPTIONS below for a full list of allowed arguments. Object Oriented interface Plot data from two arrays: use Chart::Scientific; my $plt = Chart::Scientific->new ( x_data => @x_values, y_data => @y_values, ); $plt->plot (); or piddles: use Chart::Scientific; my $plt = Chart::Scientific->new ( x_data => $x_pdl, y_data => $y_pdl, ); $plt->plot (); Plot data from an arbitrarily-delimitted file (the data in columns "vel" and "acc" vs the data in the column "time", with errorbars from the columns "vel_err" and "acc_err"): my $plt = Chart::Scientific->new ( filename => data.tab-separated, split => t, x_col => time, y_col => vel,acc, err_col => vel_err,acc_err, x_label => "time", y_label => "velocity and acceleration", ); $plt->plot (); Plot data in arrays: my $plt = Chart::Scientific->new ( x_data => @height, y_data => [ @weight, @body_mass_index ], ); $plt->plot (); Plot data in pdls: my $plt = Chart::Scientific->new ( x_data => $pdl_x, y_data => [ $pdl_y1, $pdl_y2 ], ); $plt->plot (); Plot the above data to a file: my $plt = Chart::Scientific->new ( x_data => $pdl_x, y_data => [ $pdl_y1, $pdl_y2 ], device => myplot.ps/cps, ); $plt->plot (); Generate multiple plots with the same object: my @x1 = 10..19; my @y1 = 20..29; my @y2 = 50..59; my $plt = Chart::Scientific->new ( x_data => @x1, y_data => @y1, x_label => "test x", y_label => "test y", ); $plt->setvars ( title => testa, device => 1/xs ); $plt->plot (); $plt->setvars ( title => testb, device => 2/xs ); $plt->plot ();.
