As you can see, by taking the program in small pieces and analyzing it, graphics programming does not have to be difficult. If you want to try some other plots, try these (replace lines after 600 with the lines below). The printouts from each program are shown below the listing.

The array MASK% contains the values of the dots. In order to make this program run on the most computers, we’re using only six pins for graphics. With many computers, you can use all eight available pins. In lines 90 and 100 we’ve defined some other variables you’ll be interested in LX, LXFAC, LY, and LYFAC are used as scaling factors. By changing these values, you can change the size of your printed image or even distort it you can, for example, make our circle print as an ellipse.
