datasets

This should be an array reference containing at least one dataset. The datasets can be of any type except Class::OFC::Dataset (the base class). Instead, they must be objects of some Dataset subclass.

This attribute is required.

x_axis

This should be a Chart::OFC::XAxis object.

This attribute is required.

y_axis

This should be a Chart::OFC::YAxis object.

This attribute is required.

inner_bg_color

The background color for just the chart itself, as opposed to the surrounding text.

inner_bg_color2

If this is provided, then OFC will implement a fade between the two inner background colors. If you provide this you must also provide an inner_bg_fade_angle attribute.

This attribute is optional.

inner_bg_fade_angle

A number from 0 to 359 specifying the angle of the fade between the two background colors. If you provide this you must also provide two inner background colors.
