Displaying a circle graph (circle graph display)
[Function]
This function displays several values stored in the word device or special-
function module buffer in a circle graph.
Circle graph display features are shown below:
(1)
A 16-bit or 32-bit numerical value (a negative value handled as 0) data
can be displayed as a graph.
However, a circle graph cannot contain both 16-bit and 32-bit data.
(2)
In a single circle graph, up to 16 values can be included.
Each value can be identified using different colors and fill patterns.
(3)
The circle graph is displayed in the form of a true circle.
The circle's size, radius, and central coordinate are automatically deter-
mined by setting the graph sprite frame in the circle graph display setting
window. (Drawing a circle is not necessary.)
When the vertical side of the frame does not match the horizontal one,
the shorter side is taken in the graph sprite frame setting.
