as recommended I moved here to make a new post rather than adding to an 6 year old one.
This one: http://latex-community.org/forum/viewto ... 1&start=10
by the way, sorry I don't know how to link properly.
This is a crosspost to http://tex.stackexchange.com/questions/ ... oordinates
I got the problem that the code I modified is kinda old so... well I show you:
I want this:
- What i want
- want.jpg (118.66 KiB) Viewed 6333 times
- without longitude circles
- screwed.jpg (74.43 KiB) Viewed 6333 times
- After change of estyle to style
- screwed2.jpg (105.22 KiB) Viewed 6333 times
If somebody could tell me how to place my points again it should work.
Thanks and kind regards
