meric values, graphs, lamps, and touch switches, on a screen. The screen data

Numeric values
(numeral display)
Characters and various graphics (circles, circular arcs, sectors, polylines, poly-
gons and rectangles) whose display does not have to be changed, and mark
data, image data, and library data that has already been registered, can be writ-
ten directly onto the screen.

* A continuous straight line with
up to 256 points can be drawn.
* A polygon with up to 255
vertices can be drawn.
Marks are graphics comprising 16 by 16 dots that can be used as characters.
They can be used as custom characters within character strings.
Image data are graphics comprising any required area of dots. They are regis-
tered in advance and as many as required can be displayed at any position on
the screen.
Windows bit map (BMP) data can be used for images.
There is a two-color mode, in which the display color and background color of the
image are specified when it is registered in a screen, and an eight-color mode in
which colors are assigned to the image in advance.
Since image data is composed of dots, it requires a large data size but offers
great powers of expression.
