Applying several hacks to draw labels better -- still not close to great, but bearable now. First we consider 0 amts as non-negative for annotations so they go up not down on the graph :) Second, I am applying a rough approach of knowing where the last label was drawn and draw below that, only do this for negative amts, and even then the difference between y-coords in the y-axis scale and pixels for offsets of labels, just are too annoying
