Chart::Clicker::Renderer::Bar.3pm

NAME

Chart::Clicker::Renderer::Bar - Bar renderer

DESCRIPTION

Chart::Clicker::Renderer::Bar renders a dataset as bars.

SYNOPSIS

   my $br = Chart::Clicker::Renderer::Bar->new();
 
 

NEGATIVE BARS

If you'd like to render both ``negative and positive'' bars, look at Chart::Clicker::Axis's "baseline" attribute. Setting it will result in something like this:

ATTRIBUTES

bar_padding

How much padding to put around a bar. A padding of 4 will result in 2 pixels on each side.

bar_width

Allows you to override the calculation that determines the optimal width for bars. Be careful using this as it can making things look terrible. Note that this number is divided evenly between all the values in a series when charting multiple series.

brush

Set/Get the Brush to use around each bar.

opacity

Set/Get the alpha value to make each bar more or less opaque.
