SVGGraph options: legend_font_adjust
- Option name:
legend_font_adjust- Default value:
0.6- Added in version:
- 2.6
- 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
TRUEorFALSEvalue, or any values that convert easily such as1,"1",0and"". - 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
integerorfloatvalue, 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
1or-3.2or1.63e5orM_PI. - string
- Single or double quoted strings. Remember to double-quote your strings
if you are inserting a line break:
"Line 1\nLine 2".

Ratio of font width to height.
This option assists SVGGraph in its text width calculations, and is the average ratio of the width of a character to its height.
The actual space taken up by text is unknown until the browser has drawn it, so SVGGraph has to estimate the size. The size calculation for a single line of text is:
height = font_size width = font_size * string length * font_adjust
If SVGGraph is not leaving enough room in the legend for the text, try
increasing legend_font_adjust slightly. If there is too much space around the
text, try decreasing it.
