SVGGraph options: grid_back_stripe_colour
- Option name:
- Default value:
- Added in version:
- Data type:
- colour or array [?]
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.

Colour of grid background stripes.
This option sets the colour, gradient or pattern to use for the grid background
stripes when the
grid_back_stripe option is enabled.
The value of this option should be either a single colour which will drawn alternating with an empty stripe, or an array containing a list of colours, gradients and patterns that will be used in order across the grid.
$settings['grid_back_stripe_colour'] = '#f00';
This will fill the stripes with solid red. In between the stripes the background will show through. This could be useful if you want to draw a radar graph of Captain America's shield.
$settings['grid_back_stripe_colour'] = array('#f00', '#0f0', '#00f');
This will produce red, green and blue stripes repeating. It looks like a monitor test image, so I don't recommend it.
$settings['grid_back_stripe_colour'] = array( NULL, array('#ccc', '#eee', '#ccc', 'h'), NULL, array('#eee', '#ccc', '#eee', 'h'), );
I've spread this last one across multiple lines to separate the stripes out
more clearly. The
NULL in the array means a blank stripe, so SVGGraph will
not draw anything there. The second and fourth stripes are gradients (with the
'h' at the end to make them horizontal).
For details of the colours, gradients and patterns, study the SVGGraph colour page.
