Problem: Need dynamic charting for ongoing KPI maintenance.  On a weekly basis 
we have KPI's that are updated into Excel.  Data is charted with prior 4 weeks 
(prior month), plus current 4 weeks (current month).  In Excel, each data range 
has to be manually changed in each chart each week.
Requested feature additions:  
1. Have a check box to surpress blank data points.  Example: Create a chart 
with data from rows 1 to 30 for days of the month.  On day 1 you have data, but 
the chart shows all 30 data points with blanks or -0-.  When check box is 
checked, Any data points that are blank, are not graphed.

2. Have check box to select rolling average, and field for entering number of 
recent data points to graph.  In example above, with rolling average checked, 
and graph points set to 5, the chart would graph data points 1-5. When data is 
entered for data point 6, the chart graphs points 2-6.
