DESCRIPTION

This module displays sparklines in the terminal.

METHODS

show_graph(values => \@values, max => $max)

This method builds a sparklines graph and returns it as a string.

The 'values' parameter should be a list of numbers.

The 'max' parameter is the maximum value of the graph. Without this parameter you cannot compare graphs because the scaling will change depending on the data. This parameter is optional.
