Since you just need 8 distinct positions on one switch, you can put a 10.K resistor between each adjoining pin, then each position change will add (or subtract) 10.K ohms to (from) the value, and the value can essentially range from near 0 to 100.K ohms. The diagram you showed was for discrete switches, where any give switch could be on or off.
