« Return to previous page

Option name:

inner_text

Default value:

NULL

Added in version:

2.15

Data type:

string [?]

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".

Text for centre of donut graph.

This option specifies the text that is drawn in the centre of the donut graph. The default value NULL means no text is drawn inside the donut graph. The text is always centred vertically and horizontally, so there are no options for positioning the text. The size of the centre area is entirely specified by the inner_radius option and the size of the donut graph, with no space created automatically for the text.

To draw multiple lines of text, use "\n" characters inside a double-quoted string:

$settings['inner_text'] = "Line 1\nLine 2\nLine 3";

This example will draw three lines of text inside the central area.
