Hex grids can be specified with a required size and boundary for the area of interest.  You can then specify that data in a map panel is grouped by the hex grid.

Hex grids are defined in Administration:

1. Select Administration and then Monitoring
2. Select “Show as Map”
3. Press the “Create Grid” button.

Fill in the details for the hex grid

1. Make sure the name has no spaces and is in lower case
2. Use the mouse to select the center one cell in the grid
3. Also use the mouse to select the boundaries of the grid by pressing the shift key
4. Make sure the cell width is reasonable relative to the overall grid size or it will take a long time to generate the grid

The resulting hex grid will look something like this:
