Hi guys I am not a c# guru and i think this is a good question to ask here. I have a pannel in which i am writing coordinates but since the cordinates change in every loop i when they change the panel gets the new coordinates on top of the old once. I need the panel to get refreshed before putting on top the new string. This is my code:

Graphics gc = coordinates.CreateGraphics();
            Font myFont;
            Brush myBrush;

            myFont = new System.Drawing.Font("Arial", 8, FontStyle.Regular);
            myBrush = new SolidBrush(System.Drawing.Color.Red);
            gc.DrawString("left_l_chest X = " + BodyParts[13].X.ToString(), myFont, myBrush, 10, 10);//BodyParts[13].X, BodyParts[13].Y);
gc.Dispose();

I can't insert a picture but the texts gets the new text on top without erasing the old one. any help will be apreciated. thanks

Do not write string directly to the drawing, write them to the bitmap.

....
            Bitmap btm = new Bitmap(30, 30);

            Graphics t = Graphics.FromImage(btm);
            t.Clear(Color.Black);
            t.DrawString("Text here", new Font("Arial", 20f), Brushes.Red , new PointF(1, 1));
          
            g.DrawImage(btm, new Point(15, 15));
....

Thanks mate very useful idea!
