Bubble charts display three dimensions of data. A bubble chart is a two dimensional scatter chart where each data point is represented by its size, the third dimension. This allows you to visualize the counts associated with each point. Bubble charts require at least one aggregate dimension and two other numeric dimensions.
- The X dimension must be numeric and is displayed against the X axis of the bubble chart.
- The Y dimension must be numeric and is displayed against the Y axis of the bubble chart.
- The Z dimension is normally the aggregate field and shows the value of each bubble.
For example, in the following query
logins is the Z dimension and will be displayed as the value of each bubble. The fields
longitude can be used as dimensions.
_sourceCategory=service "message=User logged in" remote_ip
| parse "[remote_ip=*]" as remote_ip
| lookup latitude, longitude, city, state from geo://location on ip = remote_ip
| count as logins by city, latitude, longitude
