The Multiple Process Sum widget lets you choose up to three Process Sum Widgets that you have created and display the data together.

An example of this widget in use, would be displaying yearly Total Recordable Injury Frequencies for three different years so that you can compare at a glance. 

In the example above the Process Sum Widgets are linked to the same processes but a Multiple Process Sum Widget could be used to compare the activities of three different processes over the same date range. 

All the processes and the Process Sum Widgets that you are going to use in the Multiple Process Sum Widget, must contain a Date Period field that is used. If they do not, the Multiple Process Sum widget will not work.
