Option name:

Default value:
1
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".

Scaling factor for bubble graphs.

This option specifies a scaling value for adjusting the size of the circles on bubble graphs. The default value 1 means a one-to-one mapping between the area of the bubbles and the Y-axis values.

If your bubbles appear too small, increase the value of bubble_scale. If they are too large, make bubble_scale closer to 0.

Example:

$settings['bubble_scale'] = 2;

This will double the radius of every bubble on the graph.
