SVGGraph options: line_dataset

« Return to SVGGraph options page

Option name:
line_dataset
Default value:
1
Added in version:
2.18
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).

array
An array(), the number and data types of its members will depend on the option for which is it used.
boolean
A boolean TRUE or FALSE value, or any values that convert easily such as 1, "1", 0 and "".
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
A colour value or one of the gradients and patterns supported by SVGGraph. See the SVGGraph colours page for details.
integer
A negative or positive whole number or 0.
number
Any number supported by PHP, for example 1 or -3.2 or 1.63e5 or M_PI.
string
Single or double quoted strings. Remember to double-quote your strings if you are inserting a line break: "Line 1\nLine 2".
Per-dataset:
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.

Example:

$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.

bar line

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.

Example:

$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.
