SVGGraph options: label_position

« Return to SVGGraph options page

Option name:
label_position
Default value:
0.75
Added in version:
1.1
Data type:
number [?]

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.

pie label

Distance of label from centre.

This option specifies how far out from the centre of the pie graph the label is displayed. The value of this option is a proportion of the distance to the edge of the pie, so the default value 0.75 is 3/4 or 75% of the way from the centre to the edge.

The value of this option can be a value greater than 1.0, which will position the labels outside the edge of the pie graph. SVGGraph will not automatically add any padding to account for this, you must update the pad_left, pad_top, pad_right and pad_bottom options to leave space.
