SYNOPSIS

DESCRIPTION

METHODS

Returns a string with a single utf8 bar according to the values

    Term::Vspark::show_bar($value_for_this_bar, $max_value, $number_of_columns_to_display);

Returns a string with a various utf8 bars according to the values

    Term::Vspark::show_graph('values' => \@values_for_this_graph, 'max' => $max_value, 'columns' => $number_of_columns_to_display);

Example:

    use Term::Vspark;
    use Term::Size;

    chomp( @ARGV = <STDIN> ) unless @ARGV;

    my @list = sort { $a <=> $b } @ARGV;
    my ($columns, $rows) = Term::Size::chars *STDOUT{IO};

    print Term::Vspark::show_graph(
        'max'     => $list[-1],
        'columns' => $columns,
        'values'  => \@ARGV,
    );

Example 2:

    chomp( @ARGV = <STDIN> ) unless @ARGV;
    my %k_values = @ARGV;

    my @list = sort { $a <=> $b } values %k_values;

    print Term::Vspark::show_labeled_graph(
        'max'      => $list[-1],
        'columns'  => 10,
        'k_values' => \%k_values,
    );

This will receive numbers from ARGV or STDIN and print out beutiful graph based on that data.
