Option name:

best_fit_combined_project

Default value:

NULL

Added in version:

3.20.4

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 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".

best-fit trend line

Combined best-fit line projections.

This option specifies whether the combined best-fit or trend line projects outside the range set using the best_fit_combined_range option. The default value NULL means the line is not extended past the specified range.

These values are supported for projecting the different ends of the best-fit lines:

• "start"

  The line is extended between the left side of the grid and the start of the range.

• "end"

  The line is extended between the end of the range and the right side of the grid.

• "both"

  The line is extended at both ends to meet the left and right sides of the grid.

The projected parts of best-fit lines are drawn with a dash pattern by default to show where the sections of line are not based on any markers with the same X value. The best_fit_combined_project_dash, best_fit_combined_project_colour, best_fit_combined_project_width and best_fit_combined_project_opacity options can be used to adjust the appearance of the projected parts of the lines.
