The formatting is specified by using the SetStyle() method as in

  $graph
->scale->day->
SetStyle(
DAYSTYLE_LONG);

The graphical formatting possibilities for days allow the possibility to specify a different color for the weekend background and also for the Sunday.

SetWeekendColor()

Set the background color for weekends. (Defaults to light gray)
SetSundayFontColor()

The Sunday font color. (Defaults to red)

In addition to this there is also a possibility to choose whether or not the weekend background should be extended vertically down over the plot area. (the default). Since that is a property more of the whole plot this behavior is modified with a call to the method

UseWeekendBackground()

of the scale, e.g.

 
 $graph->scale->UseWeekendBackground(false
);
