Hello everyone.

This time I am involved in producing maps through spmap. I've had no major problems so far, but now I can't understand how to ask STATA to show in the graph only a portion of the map. Let me be clearer: given a map of Europe, I would like to have plotted only a particular area, such as the Alps, which has been defined by a single line running around the alpine region. Looking into the graph editor, such line creates a plotregion of its own, which would be perfect, but STATA will not allow me to have on the graph only that particular plotregion, representing instead the whole of Europe. Of course, I could also use X and Y coordinates to select the region I am interested in, but here arises another issue: actually, I have asked stata to "select" only a certain region within the suboptions of "line", and STATA managed to produce a map of the selected area, the Alpine one in my case, but all other lines defining regional borders were in a mess, lacking the original order, having made a selection on the region to be plotted.

Thus, I would like STATA to show me only a certain part of the map, but without re-computing lines all around, which produces a huge mess in my graph. Thanks to anyone who is reading, I hope we can find a solution here. I can attach images if necessary.
