CLASS GanttActivityInfo
(Defined in: jpgraph_gantt.php : 142) Class usage and Overview
This class is responsible for handling the titles of the columns in the left section of the Gantt graph, i.e. the information columns for each activity.
It is instantiated in the scale and is accessed through the Gantt scale for example as in
$graph->scale->actinfo->SetColTitles(
array('Note','Name','Duration','Start','Finish'),array(30,100));
$graph->scale->actinfo->SetBackgroundColor('green:0.5@0.5');
$graph->scale->actinfo->SetFont(FF_ARIAL,FS_NORMAL,10);
$graph->scale->actinfo->vgrid->SetStyle('solid');
$graph->scale->actinfo->vgrid->SetColor('gray');
It is optional to use titles for the columns, so if you don't want to use titles you never have to add the above lines to a Gantt graph (but it sure looks nicer if you do ... )
