It's tough to find a way to express a tuner's capability in some 
succinct and meaningful way.

This was my attempt:

Each "cell" represents a particular load impedance going from 3.125 Ohms 
to 3200 Ohms in binary steps, Resistive (X axis) and Reactive (Y axis)

If the cell is green, the tuner was able to find a match, and the number 
in the cell shows the % power loss in the tuner. The darker the green, 
the better.

If the cell is red it indicates that a power dissipation limit or a 
capacitor voltage limit was exceeded

L+ indicates "no match - not enough inductance"
C- indicates "no match - too much minimum capacitance"
etc etc.

One chart needed per band.

The data was the output from the AAT programme on the Antenna Book CD.
