array, the number and data types of its members will depend on the option for which is it used. - boolean

Enables percentages for histogram.
This option enables calculating percentages for the histogram instead of using
the raw count of values. The Y axis displays a percentage value (but not the
'%' symbol - for that you should set the units_y option).
The relative heights of the bars is unchanged by this option, only their values against the Y axis change.
Example:
$settings['percentage'] = true;
$settings['units_y'] = '%';
This will display the histogram bars as percentages, with the '%' symbol in the Y axis labels.
