Gmap draw lines instead of blocks

coladuck — Mon, 13 May 2019 21:37:01 GMT

I am trying to use Proc Gmap to draw choro maps on assembly districts (one number for each assembly district and one assembly district is a block) and I have once got my results perfectly. Suddenly I lost my maps and the program can only give me maps as a bunch of lines projected out and small pieces of blocks with no assembly districts boundary. None of my data is changed. Could anyone provide me a direction on what is going on and how to solve it?

I attached the wrong map, and a correct map by counties.

Code not pictures.

The sort of scrambled area I see is typical of the boundary values not occurring in the correct order. I would look to see if you have code that sorted the map data set.

If you sorted a permanent map data set you may have to retrieve it from an archive, backup or find the code that created it.
