SetDataLabelColor — Set the color for data labels
$plot->SetDataLabelColor($color
)
SetDataLabelColor
sets the color which is used for data
labels. This includes X axis data labels (for vertical plots) or Y axis
data labels (for horizontal plots). It also includes Data Value Labels, which
show the values of data points or bars within the plot area, unless
overridden by SetDataValueLabelColor.
If SetDataLabelColor
is not used, data labels are
drawn using the general text color set with SetTextColor.
If neither SetDataLabelColor
nor
SetTextColor
is used, the default color is black.
See also Section 3.6, “Labels” for information about different label types.
PHPlot has a deprecated function called SetLabelColor
.
Do not use this function. It does not set the color used for labels.
This function was added in PHPlot-5.7.0. In earlier releases, the data label colors could only be set using SetTextColor, which also changed the color of other elements.
This version of the manual was produced for the
