SetXTitle

SetXTitle — Sets the X axis title, and optionally its position

Synopsis

$plot->SetXTitle($xtitle, [$xpos])

Description

SetXTitle sets the text to be displayed as the X axis title. Optionally, it also sets the position of the title and the axis itself: below the graph (the usual place), above the graph, both, or neither.

Parameters

$xtitle

The text string to use for the X axis title. The string can contain multiple lines, separated by newlines (in PHP: "\n").

$xpos

Optional position for the X axis and title. Use one of the following strings for the position:

PositionDescription
plotdownX axis below the plot
plotupX axis above the plot
bothOne X axis above, and one below
noneNo X axis, no X axis title

The default is 'plotdown'.

Notes

By default, there is no X axis title. If SetXTitle is called with an empty string as the title, the default behavior is restored. This includes not leaving space on the graph for the title.
