SVGGraph options: data_label_round

« Return to previous page

Option name:
data_label_round
Default value:
0
Added in version:
2.18
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.
measurement
An integer or float value, or a string containing a number followed by one of these CSS units: px, in, cm, mm, pt, pc.
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:
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.

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.

Structure:
yes [?]

Structure options may also be used as fields in the structure option's array to specify overriding settings for each data item. For more details and examples, visit the structured data page.

Example:

$settings['widget_grunge'] = 'very';
$settings['structure'] = array(
  'key' => 0, 'value' => 1,
  'widget_grunge' => 2
);

In this example widgets will be very grungy, except when a non-null item with the key 2 in the structured data array sets the grunginess to a different value.

global label structure data-label

Radius of data label corners.

This option sets the corner radius of the edge surrounding enclosed data label types.

The corner radius does not affect the padding inside the box, so it is possible for the text to overlap the curved corners. Make sure that the data_label_padding option is set to a large enough value to keep the text out of the corner:

$settings['data_label_round']   = 24;
$settings['data_label_padding'] = 12;

Circular bounding box support

Setting the data_label_round option to a non-zero value for labels without a visible surround switches to using a circular instead of rectangular bounding box, which is used for positioning the tail line.
