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

0. - measurement

- best_fit
Combines all datasets to create one line that fits all values.
The other best_fit lines each fit a single dataset, this option uses
one line to fit the data points from all datasets. To use it, set the
option to "straight" or "curve" for the type of line to draw.
The combined line does not replace other best-fit lines - they can all be drawn on the same graph.
