You can derive the percentage
of the total for a measure as a new aggregated measure. The aggregated
measure does not contain data values in itself, but when it is used
in a visualization, it displays the percentage of the total value
for the measure on which it is based.
Note: The percentage of total is
relative to the subset of data that is selected by your filters and
ranks.
For example, you might
derive the percentage of the total for a measure that contains revenue
values. If you create a bar chart of the aggregated measure and a
category that contains product lines, then the bar chart shows the
percentage of total revenue for each product line.
