Why can't I get the Forecast data to show up in Pulse?
In order to pull data from Forecasting into Pulse, the following criteria must be true:
1. In the Scope, you must select a node in the hierarchy where someone is submitting a forecast (i.e. an Admin node probably doesn't have anybody forecasting in it, but the Worldwide Sales node does).

2. In Chart Settings, select a Forecasting tab (i.e., New Business, Renewals, Product Lines, etc.)

3. At the top-right of the graph, toggle the Chart. Then, make sure you select the Forecast section:

Note: If your organization uses the role hierarchy to determine the rollup structure in the panel on the left-hand side of Forecasting, but the territory hierarchy in the Analytics Modules, then you will not be able to overlay Forecasting data in the Analytics Modules.
