Chart::Clicker::Decoration::Legend::Tabular.3pm

NAME

Chart::Clicker::Decoration::Legend::Tabular - Tabular version of Legend

DESCRIPTION

Chart::Clicker::Decoration::Legend::Tabular draws a legend on a Chart with tabular data display.

SYNOPSIS

The Tabular legend is a legend with a few extra attributes that allow you to pass it data to display. The attributes are c<header> and c<data>. The "header" (optional) allows you to specify the strings to display at the top of the table and the "data" attribute allows you to pass in arrayrefs of strings for display aside each of the series.

Note: The first string in the "header" arrayref should be the header for the column above the name of the series. This code does not do anything to verify that you've given the appropriate counts of data. It is expected that you will provide "data" with one arrayref for every series, each containing n elements. Having that, "header" will expect n + 1 elements with one for the series name and the remaining (n) matching the number of elements in each of "data"'s arrayrefs.

     $cc->legend(Chart::Clicker::Decoration::Legend::Tabular->new(
         header => [ qw(Name Min Max) ],
         data => [
             [ min(@{ $series1->values }), max(@{ $series1->values }) ],
             [ min(@{ $series2->values }), max(@{ $series2->values }) ]
         ]
     ));
