SVGGraph options: legend_position

- 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(), the number and data types of its members will depend on the option for which is it used.
- A boolean
FALSEvalue, or any values that convert easily such as
- A callable function, which can be either the name of a function or an anonymous function itself.
- 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.
- A colour value or one of the gradients and patterns supported by SVGGraph. See the SVGGraph colours page for details.
- A negative or positive whole number or
- Any number supported by PHP, for example
- Single or double quoted strings. Remember to double-quote your strings
if you are inserting a line break:
"Line 1\nLine 2".
- 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.
$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.

The legend will be at the top of the document. Default when neither top or bottom are specified.
The legend will be at the bottom of the document.
The legend will be on the left side of the document. Default when neither left or right are specified.
The legend will be on the right side of the document.
The legend will be positioned inside the grid area on grid-based graphs, or inside the padding on other types of graph. Default when neither inner or outer are specified.
The legend will be positioned at the outer edges of the document.
Position of the legend.
This option is a string specifying the position of the legend on the graph. The string should contain a combination of these keywords:
The string can also contain a pair of X and Y numeric values to offset the legend by a specific number of pixels.
The position of the legend does not affect the position of the graph, or
anything else - you must choose where to put the legend so that it does not
interfere with the graph data (or use the
The keywords in the string are read from left to right with the
top/bottom, left/right and inner/outer pairs cancelling out previous
occurrences. This means that a string like
"inner outer left top bottom right"
would give the same result as
"outer bottom right".
// empty string, same as 'inner top left' $settings['legend_position'] = '';
The default setting is the string
"top right", but the default position when
the string is empty is the top left corner inside the grid/padding area.
// bottom right of SVG document $settings['legend_position'] = 'outer bottom right';
In this example the legend will be tight against the bottom and right edges of the SVG document.
// 10 pixels from right, 20 pixels from bottom $settings['legend_position'] = 'bottom right -10 -20';
This example uses the X value
-10 and Y value
-20 to shift the legend in
from the edge of the grid space or padding area.
