disp_circle — Displays circles in a window.
disp_circle( : : WindowHandle, Row, Column, Radius : )
disp_circle displays one or several circles in the
output window. A circle is described by the center (Row,
Column) and the radius Radius.
If the used coordinates are not within the window the circle is
clipped accordingly.
The operators used to control the display of regions
(e.g., set_draw, set_gray, set_draw)
can also be used with circles. Several circles can be displayed with
one call by using tuple parameters. For the use of colors with
several circles, see set_color.
The center of the circle must be within the window.

Row (input_control) circle.center.y(-array) → (real / integer)
Row index of the center.
