SVGGraph options: minimum_units_y

« Return to previous page

Option name:
minimum_units_y
Default value:
0
Added in version:
2.10
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".
Per-dataset:
no
Multi-axis:
yes [?]

Multi-axis options allow specifying one option for all axes on a multi-axis graph, or an array of options to be used for each axis in turn. If there are more axes than entries in the option array, the sequence will be repeated.

Example:

$settings['axis_taste'] = 'banana';
$settings['axis_smell'] = ['lavender', 'lemon', 'pine'];

For this example, all axes will taste of banana, but the leftmost axis will smell of lavender, the second axis will smell of lemon and the third axis will smell of pine. If there is a fourth axis it will smell of lavender, repeating the sequence.

Minimum units to display on Y axis.

This option sets the minimum interval between divisions that SVGGraph will use for the Y axis (which is the vertical axis on the bar, line and scatter graphs and the horizontal axis on horizontal bar graphs). The default value 0 allows SVGGraph to choose any value for the interval.

The minimum_units_y option is most useful when decimal values don't make sense for the data represented on the graph. Setting the option to 1 will make SVGGraph use whole numbers for the axis labels.

For multiple Y-axis graphs this option supports an array containing a minimum interval for each axis, for example:

$settings['minimum_units_y'] = array(0, 1);

To set a fixed interval for the axis divisions, use the grid_division_v and grid_division_h options.
