« Return to previous page

Option name:

log_axis_x_base

Default value:

10

Added in version:

3.12

Data type:

numeric [?]

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".

axis

Specifies logarithm base for use on logarithmic X-axis.

This option sets the base of the logarithm SVGGraph will use for the X axis when the log_axis_x option is enabled. SVGGraph will use the base for choosing the axis divisions. The base value must be greater than 1.0, but it does not have to be an integer.
