Hello list, I am trying to create a MapBasic application that converts text files to points and automatically displays different point files on a map. This works fine but I would like the final display to be automatically set so that it zooms in on the smallest area possible that contains four different layers of points. I can use zoom entire layer to zoom to one layer of points or I can write in a certain zoom scale but this changes depending on where the points are generated. Neither of these are quite what I want. How can I zoom to entire of four layers ? Any help would be greatly appreciated. Elliot.
