- string [?]
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".
- no [?]
Per-dataset options allow specifying one option for all datasets or an array of options to be used for each dataset in turn. If there are more datasets than entries in the option array, the sequence will be repeated.
$settings['widget_taste'] = 'banana'; $settings['widget_colour'] = array( 'red', 'green', 'blue' );
For this example, the widgets for all datasets will taste of banana. The graph will use red widgets for dataset 0, green widgets for dataset 1 and blue widgets for dataset 2. Dataset 3 repeats the sequence so its widgets will be red, dataset 4 will have green widgets and dataset 5 will have blue widgets.

Text label for vertical axis.
This option sets a text label to display next to the vertical axis. The
default value is an empty string and no label is displayed. For multiple lines
of text, use a
\n character and remember to quote the string using
$settings['label_v'] = "Bananas per chicken\n(I've run out of ideas)";
For multiple Y-axis graphs the option supports an array containing a label for each axis, for example:
$settings['label_v'] = array('Pints of lager sold', 'Takeaway meal sales');
The lines that make up the text label are rotated through 90° with the bottom of the text nearest to the axis and the text centred relative to the grid area.
label_v option always labels the vertical axis and takes precedence
label_y options. For radar graphs the vertical axis
is the one that goes from the centre of the graph outwards.
