Hypatia::Chart::Clicker::Bar - Bar Charts with Hypatia and Chart::Clicker
The required column types are
y (ie the default given by Hypatia).
Each of the values for this attribute may be either a string (indicating one column) or an array reference of strings (indicating several columns).
In the latter case,
the number of
y columns must match and each respective
y column will form its own bar chart.
In the former case,
x column will act as the same
x column for all of the
columns attribute is not set,
then column guessing is used as needed via the algorithm described in Hypatia::Chart::Clicker::Role::XY.
A boolean value indicating whether or not the graph should be a stacked bar graph (ie whether or not the y values should be treated cumulatively). This is disabled by default.
A numeric value indicating where the baseline should be on the y-axis. Bars with values below the baseline will be considered "negative", and will point downwards. Take a look at https://github.com/gphat/chart-clicker-examples/blob/master/bar/bar-baseline.png and https://github.com/gphat/chart-clicker-examples/blob/master/bar/bar-baseline.pl for an example.
If this attribute isn't set (which is the default), then there is no baseline.
