Figure 6-14: The Region visualization type.
Adding categories
You can add analyses to your maps by selecting different dimension fields from the Category menu.
You can turn your ordinary column plots into multicolored clustered or stacked columns.
Figure 6-15 shows the path of Hurricane Katrina in the Column visualization type and the Wind Speed
measure in the Height field. So the varying column sizes are based on wind speed.
To enhance the map, we've added the Hurricane Category field to the Category field. This adds a
legend to the map and gives each column a different color based on the Hurricane Category status
defined at each plot point.
Use the two chart icons next to the Category box to switch between seeing the data as clustered
columns or stacked columns.
If you add a dimension field to the Category box and you leave the Height box blank,
Power Map automatically adds that same field to Height and draws a visual that
represents the count of each category.
Note
Visualizing data over time
Power Map can create time-based animations, allowing you to visualize how your data points change
over time.
