The bars of the Pareto chart are live, meaning that a user can hover the mouse
over one and get a pop-up window that shows the actual value as well as the
percentages of the group and total. In addition, clicking on one of the bars will
make that box visible if it is not already. This is useful for clicking on a bar that
represents a member that is stacked up on the left or right. The member for that bar
is automatically dealt to the visible region, and other members are stacked up on the
left or right as necessary.
The Pareto chart can be customized to some degree using the two buttons located
off to the right of it. The top button will toggle just the percentage line on and off,
while the bottom button will toggle the entire Pareto chart on and off. Finally,
clicking on either the left or right axis will cycle through a series of turning off all
the grid lines, turning on just grid lines for the axis on which the user is clicking, and
turning on grid lines for both the left and right axes.
Returning to the decomp itself, the full power has not yet been demonstrated. In
Figure 6-44, the user has drilled down to the City level, and if he or she clicks on
M??nchen, Postal Code will be shown (and after that the individual customers). After
drilling down to the lowest level in the dimension, what??™s next? In this case, there is
a customer named Jos?© E. Saraiva who has ordered approximately $8,000 worth of
products from the Adventure Works company.
