NAME
Term::Vspark - Displays a graph in the terminal
SYNOPSIS
use Term::Vspark qw/show_graph/;
binmode STDOUT, ':encoding(UTF-8)';
print show_graph(
values => [0,1,2,3,4,5],
labels => [0,1,2,3,4,5], # optional
max => 7, # optional
columns => 80, # optional
);
# The output looks like this:
# 0 ▏
# 1 ██████████▉
# 2 █████████████████████▊
# 3 ████████████████████████████████▋
# 4 ███████████████████████████████████████████▌
# 5 ██████████████████████████████████████████████████████▍DESCRIPTION
This module displays beautiful graphs in the terminal. It is a companion to Term::Spark but instead of displaying normal sparklines it displays "vertical" sparklines.
Note that because the graph is built from utf8 characters, users must setup UTF-8 encoding for STDOUT if they wish to print the output.
METHODS
show_graph(%params)
show_graph() returns a string.
The 'values' parameter should be an ArrayRef of numbers. This is required.
The 'labels' parameter should be an ArrayRef of strings. This is optional. Each label will be used with the corresponding value.
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.
The 'columns' parameter is the maximum width of the graph.
