Data type:
boolean [?]

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.
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".

pie label data-label

Shows item key in data label.

This option enables displaying the key for the data item in its label on pie graphs. It is enabled by default because data items are normally identified by their key value, which is especially important when the items are not in their natural order (i.e. when the sort option is enabled).

The three different parts of the pie graph labels are drawn on separate lines with the key at the top, then the amount in the middle and the percentage at the bottom.

For more control over the labels, see the data_label_callback option.
