Since the area you have to work with is limited it is better to use several diagrams, graphs, or charts rather than put a great deal of information on a single visual. Limit text to four or five line containing three to five words. Use simple type face with broad strokes. Video Monitors and Computer Displays Video monitors use an interlaced system of screen refresh. These fields are traced alternately, first the odd lines from top to bottom, then the even lines from top to bottom.
Most computer displays have non-interlaced pattern where all the lines are drawn in a single pass.
As a result isolated single pixel graphic components do not work for video graphics, even though they look fine on the computer monitor. Horizontal lines of more than one pixel will ease the problem. Avoiding the buzz will also affect the type face you use. When you are choosing a type face avoid scripts, cursives, italics, condensed faces and novelty or decorative styles. These will be difficult to read, digitize and reproduce.
