| I need to know how I can remove ellipses that I have drawn on top of an MTrend widget using PgDrawArc(). If I make a call to PtDamageWidget() will this cause the ellipses that were drawn on the MTrend widget to disappear? If not, what should I do? Thanks |

| When you call PtDamageWidget() on your MTrend-Widget it will redraw the widget on the next update. As long as you do not draw the ellipses constantly they should disappear. |

| and to make the next update immediate I should call PtFlush() after PtDamageWidget()...is that correct? |
