SVGGraph options: log_axis_x
- Option name:
- Default value:
- Added in version:
- Data type:
- boolean [?]
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".

Enables logarithmic scale for X-axis.
This option changes the scale on the X-axis from evenly-spaced divisions to logarithmic divisions. This is most useful for line or scatter graphs, though it can be used with bar graphs too - but a logarithmic X-axis cannot start at 0.
