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(), the number and data types of its members will depend on the option for which is it used.
- A boolean
FALSEvalue, or any values that convert easily such as
- 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
- Any number supported by PHP, for example
- Single or double quoted strings. Remember to double-quote your strings
if you are inserting a line break:
"Line 1\nLine 2".

Opacity of legend when hidden.
The default value for this option is 0, which means the legend becomes
completely invisible when the cursor enters the legend and the
option is enabled. The option can be set to any value between 0 and 1 to make
the legend translucent instead.
Also, the value can be set to a value between -1 and 0 to reverse the opacity change when the cursor enters the legend. A value of 0.5 will make the legend 50% opaque until the cursor enters it when it will then become fully opaque.
