Azimuthal projection, Excell and a question(need some e...

Hey all,I recently started experimenting with Excell(XP)I'm using a wonderfull spreadsheet by Rob v. Leest, Wagner B. Beskow and Ilan Jonas. I have:* Coordinates of waypoints* An azimuthal projectional weather chartIs there anyone here who can tell me how i:* create a macro that plots the waypoints(via the coordinates) onto the azimuthal weather chart(TIFF file)* make the macro connect the waypoints by lines. I know this may not be very easy, but i wanna give it a go anyway. I hope someone knows enough to help me with this.CheersLenny
