Hi Leonid! First let me say I am very, very impressed by the codes you submitted. I have the idea of joining the idea presented in the example "Drawing overlays on SAS-generated Google maps" with this one presented here. It is about expandig polygons during daytime (for example for every hour of the day the shape of the polygon is changing) and adding some statistical description, so I have two problems to solve - one is to make the map dynamic (it is possible with animated gif but I don't know how to make it with html output). The second is to present the legend for different colours of the polygons. Could you somehow help me with this? Kind regards, Tomasz
