The datatypes used in this documentation for specifying SVGGraph options are described below. All options can be a literal value of the data type described, a variable containing the data type, or an expression that will produce the data type when evaluated (and they must always be valid PHP expressions).

array
An array, the number and data types of its members will depend on the option for which is it used.
boolean
A boolean TRUE or FALSE value, or any values that convert easily such as 1, "1", 0 and "".
callback
A callable function, which can be either the name of a function or an anonymous function itself.
colour
Any of the colour values supported by SVG inside a single or double quoted string. These include three and six digit hex codes, RGB and RGBA colours, and colour names. SVG uses "none" for no colour, which generally leaves things transparent.
fill
A colour value or one of the gradients and patterns supported by SVGGraph. See the SVGGraph colours page for details.
integer
A negative or positive whole number or 0.
measurement
An integer or float value, or a string containing a number followed by one of these CSS units: px, in, cm, mm, pt, pc.
number
Any number supported by PHP, for example 1 or -3.2 or 1.63e5 or M_PI.
string
Single or double quoted strings. Remember to double-quote your strings if you are inserting a line break:
"Line 1\nLine 2".

Inner radius of donut graph.

This option specifies the radius of the inner rim of the donut graph as a multiplier of the outer radius. The default value 0.5 means that the inner radius will be 1/2 or 50% of the radius of the outer edge of the donut.

The option supports values between 0.01 and 0.99 (but extreme values don't look much like donuts).

The text inside the centre of the donut is set using the inner_text option.
