SVGGraph options: end_angle

« Return to SVGGraph options page

Option name:
end_angle
Default value:
"none"
Added in version:
2.24
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

End angle of pie graphs.

The default value of this option, "none", means that the end angle will be 360° from the start angle, drawing a whole pie graph.

Changing the value of the end_angle sets the end angle of the pie, which must be somewhere between start_angle and start_angle + 360. SVGGraph calculates slice sizes based on the difference between end_angle and start_angle, so changing the end angle scales the slices proportionately.

This option is used internally by the SemiDonutGraph to set its end angle 180° from its start instead of 360° and cannot be overridden. If you want a semi-donut graph that does not start at 0°, use a DonutGraph and set both start and end angles.

Version 2.25 is the first to support drawing the sides of 3D pie graphs correctly when the pie is not complete.
