D2Plot x!, y! [,D2Brush]
| x!, y! | : float expression |
| D2Brush | : Object expression |
Draws a rounded dot at x,y in device-independent pixels. By default, the dot is drawn using a solid color brush created from the current foreground color D2ForeColor. If the application passes a D2Brush object the dot is painted with that brush.
