1UNRESOLVED BUGS
2
3+ two_axes doesn't work correctly with negative numbers and zero_axis
4+ y_max_value doesn't get adapted for bars and area if all negative values
5+ init_graph does too much work for pies. Needs to be split up.
6+ area chart doesn't do overwrite? Workaround: sum up your data sets,
7  and order them backwards (highest one first). Output graph will look
8  like it's incremental.
9+ only bar charts do overwrite. Necessary to implement generally?

11NOT REALLY BUGS
12
13- The whole naming of x_label.*, x_tick.*, x_axis.* is very confused
14  and confusing. Hard to fix without breaking backward compatibility.
15- overwrite == 2 only makes sense if all the data is either positive,
16  or negative
17- A positive y_min_value doesn't work with bars or area, bars and area
18  always are set off against 0. Wether this is a bug, or wanted behaviour
19  might be a point for discussion.
20- y_min_value doesn't automatically get adapted for bars and area if 0
21  is not included in the range, but only if user sets it. If left to
22  figure it out itself, PNGgraph does it right.
