I draw elevation profiles showing height gain / loss along the path, as shown below:
Example elevation profile with manually placed tags http://img38.imageshack.us/img38/4079/profilewithgoodlabels.png
This is basically a linear graph with distance from the start along the x axis and elevation along the y axis.
I would like to provide vivid labels with place points at interesting points along the trail, like the ones I manually added to the sample. I am looking for ideas on how to better place these labels so that:
- They do not overlap with each other.
- They do not overlap with the profile itself, or at least it happens in its pure form (it seems that this may be necessary, for example, in the middle of a steep valley)
- They do not go beyond restricting the overall image.
To achieve these goals, I believe that I can (at least):
- Flip the text around (see example)
- Choose the right length for leaders
- Choose suitable angles for leaders (but minimizing variation may be desirable for aesthetic reasons).
- High elevation marks for less important locations in crowded areas.
- Abbreviated names in crowded areas (
PlaceNamemy environment already supports the abbreviation in really good form, so the transition from "South Twin Mountain" to "S Twin Mtn" is simple). - Discard less important annotations completely in crowded areas.
