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
floatvalue, or a string containing a number followed by one of these CSS units:
- 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".
- yes [?]
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.
- Supported by:
Sets bar position of line markers on bar and line graphs.
The default location of the line markers on bar and line graphs is in the middle of the group of bars. This option allows you to specify which bar the marker is drawn over.
This is a per-dataset option, though the line datasets map to bar positions and not the dataset of the bar.
$settings['line_dataset'] = [4, 5, 6, 7]; $settings['line_bar'] = [null, null, null, null, 0, 1, null, 1];
This example draws datasets 4, 5, 6 and 7 as lines, with the marker for dataset 4 above the first bar, the marker for dataset 5 above the second bar, the marker for dataset 6 in the middle of the bars and the marker for dataset 7 above the second bar.
