About MapsThe Cancer Atlas Viewer displays maps in a two-pane window. The left pane serves as a map legend, listing the variables and their symbols, and provides a way to manage layers in the map. The right pane contains the map itself.

The map legend panel lists all the layers in the map. You may show or hide a map layer by checking or clearing its associated box using the mouse. Displayed layers have a check in the box next to their name. You can delete a layer from a map by selecting it and then hitting the delete key.
To change the order of layers in a map or datasets in a layer, drag layers or datasets up or down the list.
You can add layers to an existing map by right-clicking a geography in the data view and choosing "View in map". Or, you can click on a dataset in the data view and drag it into the left panel (onto the word "Layers" at the top)
You can close the legend by clicking on the [x] button on the top right. To bring the legend back, right click on the blank toolbar area to the right of the map tools and choose "legend" from the pop-up menu.
You can use the map toolbar to zoom, select, and query the map. You can view a slideshow of any of the datasets associated with a particular map.
You can interact with the map using the map or animation toolbars. You can export, print, or view map properties from the Map menu.
In the lower left of the map, the status bar shows the coordinates of the mouse pointer, if it is hovering over the map. The coordinates are in the projection of the geography, viewable in the geography properties.
