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".

Multi-axis options allow specifying one option for all axes on a multi-axis graph, or an array of options to be used for each axis in turn. If there are more axes than entries in the option array, the sequence will be repeated.
$settings['axis_taste'] = 'banana'; $settings['axis_smell'] = ['lavender', 'lemon', 'pine'];
For this example, all axes will taste of banana, but the leftmost axis will smell of lavender, the second axis will smell of lemon and the third axis will smell of pine. If there is a fourth axis it will smell of lavender, repeating the sequence.

Minimum value for vertical axis.
This option specifies the minimum value for the vertical axis, overriding the value that SVGGraph would choose automatically. The automatic minimum is usually 0, though it can be a negative number if the data contains negative values.
$settings['axis_min_v'] = 100;
Note: this option sets the vertical axis, which is the Y axis on vertical bar, line and scatter graphs, and the X axis on horizontal bar graphs. On a radar graph it is the axis going out from the centre of the graph, which corresponds with the Y axis.
For multiple Y-axis graphs this option supports an array containing a minimum for each axis, for example:
$settings['axis_min_v'] = array(0, 1000);
This sets the minimum for the left axis to 0 and the minimum for the right axis
to 1000. A
NULL in the array uses the default value that SVGGraph would have
