Data type:
array [?]

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).

An array, the number and data types of its members will depend on the option for which is it used.
A boolean TRUE or FALSE value, or any values that convert easily such as 1, "1", 0 and "".
A callable function, which can be either the name of a function or an anonymous function itself.
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.
A colour value or one of the gradients and patterns supported by SVGGraph. See the SVGGraph colours page for details.
A negative or positive whole number or 0.
An integer or float value, or a string containing a number followed by one of these CSS units: px, in, cm, mm, pt, pc.
Any number supported by PHP, for example 1 or -3.2 or 1.63e5 or M_PI.
Single or double quoted strings. Remember to double-quote your strings if you are inserting a line break:
"Line 1\nLine 2".

Gradient for shading pie/cylinder.

This option specifies the gradient used to fill the overlay drawn over the top of the 3D pie or cylinder side area to improve the 3D effect. The default gradients use a black fill colour with varying opacity to produce a lighting effect.

The default gradient for cylinder graphs:

array("black:0.6", "black:0", "black:0.9", "h")

The default gradient for 3D pie graphs:

array("black:0.9", "black:0", "black:0.9", "h")

Note the "h" at the end of the gradient to mark it as horizontal. Without this you will get a vertical gradient, which doesn't look right.
