NAME

Graphics::GnuplotIF::Shortcut - Alternate interface to Graphics::GnuplotIF

VERSION

This document describes Graphics::GnuplotIF::Shortcut version 0.03

SYNOPSIS

    use Graphics::GnuplotIF::Shortcut;

DESCRIPTION

Graphics::GnuplotIF::Shortcut is a wrapper for Graphics::GnuplotIF. The advatage of Graphics::GnuplotIF::Shortcut over Graphics::GnuplotIF is that the code is much better to read.

Graphics::GnuplotIF::Shortcut inherits from Graphics::GnuplotIF. But you can call all method calls prefixed with gnuplot_ without gnuplot_.

For example instead of this code:

  ###
  ###  Graphics::GnuplotIF
  ###

  my  $gp  = Graphics::GnuplotIF->new;

  $gp->gnuplot_set_xrange(  0, 4 ); 
  $gp->gnuplot_set_yrange( -2, 2 );
  $gp->gnuplot_cmd( "set grid" ); 
  $gp->gnuplot_plot_equation(    
    "y1(x) = sin(x)",
    "y2(x) = cos(x)",
    "y3(x) = sin(x)/x" );

  $gp->gnuplot_pause();   
  $gp->gnuplot_plot_equation( "y4(x) = 2*exp(-x)*sin(4*x)" );
  $gp->gnuplot_pause( );      

you can write the above or the one bellow or a mixture of both.

  ###
  ###  Graphics::GnuplotIF::Shortcut
  ###
  
  my  $gp  = Graphics::GnuplotIF::Shortcut->new;

  $gp->set_xrange(  0, 4 ); 
  $gp->set_yrange( -2, 2 );
  $gp->cmd( "set grid" ); 
  $gp->plot_equation(    
    "y1(x) = sin(x)",
    "y2(x) = cos(x)",
    "y3(x) = sin(x)/x" );

  $gp->pause();
  $gp->plot_equation( "y4(x) = 2*exp(-x)*sin(4*x)" );
  $gp->pause();
