SVGGraph options: label_v

« Return to previous page

Option name:
label_v
Default value:
""
Added in version:
2.6
Data type:
string [?]

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
Multi-axis:
yes [?]

Multi-axis options allow specifying one option for all axes on a multi-axis graph, or an array of options to be used for each axis in turn. If there are more axes than entries in the option array, the sequence will be repeated.

Example:

$settings['axis_taste'] = 'banana';
$settings['axis_smell'] = ['lavender', 'lemon', 'pine'];

For this example, all axes will taste of banana, but the leftmost axis will smell of lavender, the second axis will smell of lemon and the third axis will smell of pine. If there is a fourth axis it will smell of lavender, repeating the sequence.

Text label for vertical axis.

This option sets a text label to display next to the vertical axis. The default value is an empty string and no label is displayed. For multiple lines of text, use a \n character and remember to quote the string using double-quote marks:

$settings['label_v'] = "Bananas per chicken\n(I've run out of ideas)";

For multiple Y-axis graphs the option supports an array containing a label for each axis, for example:

$settings['label_v'] = array('Pints of lager sold', 'Takeaway meal sales');

The lines that make up the text label are rotated through 90° with the bottom of the text nearest to the axis and the text centred relative to the grid area.

The label_v option always labels the vertical axis and takes precedence over the label_x and label_y options. For radar graphs the vertical axis is the one that goes from the centre of the graph outwards.
