SetLineWidths
SetLineWidths — Set line width (thickness) for each data set
Synopsis
$plot->SetLineWidths($lw)
Description
SetLineWidths sets the desired line width to be used
when plotting each data set.
Parameters
$lw
An array of line widths in pixels, one for each data set to be plotted.
Or, a single value to be used for all data sets.
Notes
If an array is used for $lw, it
must use zero based sequential integer indexes. This is what the PHP manual
calls 'the usual integer indices (starting from zero, increasing by one)'.
By default, all data set plot lines are 1 pixel wide.
