Filter Types
Graph filters and refine filters are available and may be combined to refine your charts.
Graph Filters
On a chart, click the element (a point on a line, a bar, a pie chart slice, etc.) you want the page to be refined on. The corresponding filter is added to the Active Filters bar and the page immediately reloads to apply it to its content.
On pages that show charts based on different object types that are related to one another, filters impact all of these objects. For example, if you refine change orders from the Identify page, change requests charts will also be affected by the filters.
Refine Filters
Click Filter 
in the upper-right hand
corner to open the refine panel. Filters are organized by business objects and may display
several values. For example, the 'owner' filter may display the following values: owner
#1, owner #2, and owner #3. You can click as many values as you want from the same filter.
For example, you can click owner #1 and owner #2. You can also refine the list of
available filters by entering a filter or value name in the Search for
filter... field that is displayed in the upper-right hand corner.
