Option name:

increment

Default value:

NULL

Added in version:

2.19

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".

Histogram

Tags:

histogram axis

X-axis increment for histograms.

This option specifies the increment used to split the data values into bars on the X-axis of a histogram. The default value NULL means that SVGGraph will pick an increment that divides the values available into a reasonable number of bars.

Example:

$settings['increment'] = 100;

This will divide the values up into hundreds; there will be a bar counting values from 0-100, a bar for values from 100-200, one for values from 200-300 and so on.
