Data type:
integer or 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).

An array, the number and data types of its members will depend on the option for which is it used.
A boolean TRUE or FALSE value, or any values that convert easily such as 1, "1", 0 and "".
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 0.
An integer or float value, or a string containing a number followed by one of these CSS units: px, in, cm, mm, pt, pc.
Any number supported by PHP, for example 1 or -3.2 or 1.63e5 or M_PI.
Single or double quoted strings. Remember to double-quote your strings if you are inserting a line break:
"Line 1\nLine 2".

Datasets to draw as lines.

This option specifies which datasets should be drawn as lines on the bar and line graphs. The default value 1 means that dataset 0 should be drawn as bars, dataset 1 will be drawn as a line and any other datasets will be drawn as bars. Multiple datasets may be specified as lines using an array of dataset numbers.

Multiple datasets of bars are grouped on a bar and line graph, with the data points for line datasets drawn in the horizontal centre of the group of bars.


$settings['line_dataset'] = array(2, 3);

This example will display datasets 0 and 1 as grouped bars, with datasets 2 and 3 as lines. Any other datasets will be displayed as bars, grouped with datasets 0 and 1.
