// ----------------------------------------------- drawQuestionnaireGraph
	// This function is intended to support dynamic rendering of questionnaire counts diagrams
	//  - Preconditions: 'diagram' is a preconfigured diagram object 
	//    (setBorder, XScale, YSubGrids, SetText, SetGridColor, Font and Draw are done)
	//  - 'qdata' is a list (array) of datasets, each formed as an array with a 'counts' subarray 
	//     each array is set up like this: 
	//		  id => 1
	//		  title => Questions, #1
	//		  text => Will you vote for our Candidate for W...
	//		  goal => 1000  ### 0 means no goal
	//		  today => Sep 15, 2007
	//		  first_date => Aug 21, 2007
	//		  last_date => Sep 14, 2007
	//		  first_graph_date => Mar 28, 2007
	//		  last_graph_date => Sep 14, 2007
	//		  election_date => Nov 04, 2008
	//		  days => 25
	//		  total_count => 195
	//		  max_count => 29
	//		  total_value => 468 ### optional
	//		  max_value => 68    ### optional
	//		  counts => Array (11)
	//		    0 => Array (5)
	//		      date => Aug 21, 2007
	//		      count => 8
	//		      value => 20
	//		      accumulated_count => 8
	//		      accumulated_value => 20    ### optional
	//  - 'qid' is an index indicating which questionnaire we want to appear - the others will have their visibility turned off
	//	 - 'frame_width' is the width of the plotted graph in pixels
	//	 - 'frame_height' is the height of the plotted graph in pixels
	//	 - 'date_start' can be 'data', 'all', 'today' or a starting date in the form "MonthName DD, YYYY", e.g. "Sep 07, 2007" - VERY STRICT
	//		- default is 'all' which means starting at the earliest data point from all graphs
	//	 - 'date_end'  can be 'data', 'all', 'today', or an ending date in the form "Sep 08, 2008" 
	//		- default is 'all' which means ending today or election day, whichever is later)
	//   - 'chart_type' indicates which type of data will be plotted; 'accumulated' counts/values as a line graph or 'daily' counts/values as a bar chart, or 'both' superimposed
	//   - 'values' if "N" ((default is "Y"), indicates that values, when available, will not be plotted in favor of plotting counts; "B" means plot both superimposed; "Y" (default) means plot values when available, otherwise counts
