Option name:

Default value:

Added in version:

Data type:
number [?]

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.
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".

global legend

Ratio of font width to height.

This option assists SVGGraph in its text width calculations, and is the average ratio of the width of a character to its height.

The actual space taken up by text is unknown until the browser has drawn it, so SVGGraph has to estimate the size. The size calculation for a single line of text is:

height = font_size
width  = font_size * string length * font_adjust

If SVGGraph is not leaving enough room in the legend for the text, try increasing legend_font_adjust slightly. If there is too much space around the text, try decreasing it.
