It should be connected exactly as the same MAX7219 driver for 7-segment display, connected directly (not using multiplexer) as described here:
http://simvim.com/svc_numbers.html

Configuration: Click an empty pin (only numbers 30-37 can be used for matrix) and select the "Add LED Matrix, 7219" extension type (not "LED Driver"!) .
This pin will be used to connect the "CLK"  input.
The DIN and CS are connected accordingly to the common "D" and "L"  signals.

In the configurator image map or parameter table, select any parameter suitable for digital output  or variable parameter for linear LED graph indicator, and assign it to one of the LED Driver outputs (from 0 to 63).
