SVGGraph options: datetime_key_format
- Option name:
datetime_key_format- Default value:
NULL- Added in version:
- 2.23.1
- Data type:
- string [?]
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".

- datetime_keys datetime_text_format
This option specifies the date/time format of the data keys, used when the
datetime_keys option is enabled. The default value of NULL means that no
specific format is in use.
The format should be a string containing the format characters described in the PHP DateTime::createFromFormat documentation:
$settings['datetime_key_format'] = 'm.d.Y';
This example sets the format to read a date only with the month first, then the day of the month, then the year, with the fields separated by full stop characters.
If PHP fails to convert the date using the provided format SVGGraph will try again using the default format before giving up.
