UI for Reporting sales history

[Bill Weale]

My starting point is a graphical representation of unit or $$ sales (y-
axis) over time (x-axis). No problem there.

The users' most "interesting" features are the up- and down-sloping  
areas and the steeper they are, the more interesting they are.

8-)

I want to add functionality so that 1) the user can specify the  
threshold slope above which he wants to limit his attention, i.e.  
allow him to view only those products which exceed a slope of a  
minimum positive or negative value. But the user's concept of slope  
won't necessarily be the literal y/x value; it will be the change in  
qty or $$ of sales over a period of xx days weeks or months.

I'm looking for some ideas how to set up the ui for this.

I had some initial thoughts of providing an interactive "test" graph  
in which the user could experiment by entering qty or $$ and time  
values. The graph would be redrawn so he could see what the slope  
looked like and go from there. But maybe someone has experience with  
something else? Something simpler?

Thanks,

Bill


PS

Is there an approach in 4D which would yield a "list" of graphs,  
similar to an output or included form, one for each product?
