My only trouble is that I can't manage to get multiple data series into the same plot. Does anyone have a s...
Lets say i have a model A. Then, i have several models B, C, D, E etc that each have a foreignKey to model A. I know that i can set B, C, D etc as inlines to model A so that when i create a model A it will show formsets for adding multiple items for each subModel, but i think this would make a fairly cluttered and very large page.

I have a collection of parse trees, and they are in this ascii representation where indentation determines the structure (and closing brackets are implicit). I need to convert them to s-expressions so that parentheses determine the structure. It's a little bit like python's significant whitespace vs. braces. The input format is a vertica...
