Welcome to the PICAXE Forum.

There doesn't seem to be any information for that model of display on the internet, other than this:

"Common anode"

How many pins does this display have? If it has a small number (e.g. 12) then it will be multiplexed, and you can find examples of how to drive a multiplexed display on the forum.
If it has many pins (e.g. 30), then it is not multiplexed and it can be treated as four separate displays. This could be a problem due to the number of I/O pins required, so it will probably be necessary to wire it up so that it is multiplexed.

A link to the datasheet for the display (or upload an image) or details on the displays internal schematic are required.

Which PICAXE chip are you intending to use for your project?
How many IO pins can be assigned to the display. 4-digit Multiplexed display will need around 12 pins.
