SVGGraph options: depth_shade_gradient
- Option name:
depth_shade_gradient- Default value:
array(...)- Added in version:
- 2.10
- 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).
- array
- An
array, the number and data types of its members will depend on the option for which is it used. - boolean
- A boolean
TRUEorFALSEvalue, or any values that convert easily such as1,"1",0and"". - 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
integerorfloatvalue, 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
1or-3.2or1.63e5orM_PI. - string
- Single or double quoted strings. Remember to double-quote your strings
if you are inserting a line break:
"Line 1\nLine 2".
- Per-dataset:
- no

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.
