Draw Arc (Not in Base Package)

Draws an arc in a picture. Details

arc size specifies the length of the arc.
start angle is where the arc begins.
picture is the picture to which you want to add the arc. It defaults to an empty picture if you do not wire it.
rect is a cluster containing four numerics that describe the left, top, right, and bottom coordinates of the outer edges of the rectangle.
left is the horizontal coordinate of the left edge of the rectangle.
top is the vertical coordinate of the top edge of the rectangle.
right is the horizontal coordinate of the right edge of the rectangle.
bottom is the vertical coordinate of the bottom edge of the rectangle.
fill? specifies whether to fill the rectangle. If FALSE (default), the VI draws only the arc component and does not draw interior bounds of the wedge.
color is the color of the lines. If the interior is filled, the VI uses this color for the interior. The default is black.

You can wire a color box constant to this input.

black in B/W? specifies whether the pixel appears as black or as white if you display it on a black-and-white monitor. The default is black (TRUE).
new picture is the modified picture.

Draw Arc Details

A rectangle specifies the size of an oval that contains the arc. Thus, the arc may not fill the whole rectangle. LabVIEW specifies the angles that describe the arc in degrees. It can range from -360° to 360°, with positive angles appearing clockwise, and negative angles appearing counterclockwise. Zero degrees is straight up.

LabVIEW measures all angles as though the enclosing rectangle were square. Thus, a line from the center to the upper-right corner describes an angle of 45°. The following illustration shows the conventions used in specifying the angle of a point of an arc.
