our client colleagues that, since the default position for the legend is to the
right of the chart area, and since our exploded pie chart may be wider than
expected, due to its nature and the amount of data we are presenting, placing
the legend underneath the chart will offer another means of more efficiently
arranging the overall presentation.

3D Effect Tab
Click the 3D
We inform our client colleagues that the 3D Effect tab
offers us a means of transforming the ordinarily flat appearance of our Exploded
Pie chart to a highly customizable, three dimensional presentation. Here we
can enable 3-D visual effects (via the checkbox to the immediate left of the Display
chart with 3-D visual effect label). The four variables that we can manipulate
Once 3-D visual effects are enabled, a slider becomes
enabled for each of these variables, which we can move to adjust each variable

We will examine
the final remaining tab, Filters, in the next subsection.
Click the Filters
The Filters tab is but one option we have, within Reporting
Services, to filter the data that are displayed within our chart. We advise
our client colleagues that we performed all desired filtering at the dataset
level earlier within our practice session. When this is adequate (that is,
when we can effectively filter at the dataset level for the entire report), we
may achieve performance gains at report runtime, due to the overall retrieval
of less data from the Analysis Services data source. But, we caution the
client representatives, due consideration should be given to the various points
at which we can filter within a given report, to ascertain that we optimize
performance while retaining complete and accurate information for presentation.
The Filters tab allows us to choose either dataset columns
or expressions to filter data at the chart level. This might make sense as a
filter point if we were, say, using multiple data regions (charts, matrices,
tables, lists, or a combination of these, perhaps) that were sharing the same
common dataset(s), but where each region had different filtering requirements
and needed to present different subsets of data from the underlying dataset(s).
Whatever our needs, Reporting Services, once again, offers flexibility in ways
to meet the challenges involved.
