Have a look here: Not sure what’s wrong with your code, but I might have a simpler solution for you.

By contrast, the versatility of a dot-matrix arrangement allows an LED unit to display complicated shapes. To accommodate the 5×7 LED matrix on a solderless breadboard, two of them are required for proper mounting of 5xx7 optoelectronic display.

I have just ordered an arduino and have the max chip sat beside me. In other words, make sure the hardware is working with the simplest code you can.
