Limit y-axis to min zero when showing counts #1

Open pkienzle opened 10 years ago

bmaranville commented 10 years ago

I'm not sure I agree with this... if negative axis values are ever shown for counts, they will necessarily be in the expected "marginal" region of the graph. Forcing zero as the lower limit will lead to some ugly graphs with points stuck to the bottom axis. I don't think anyone will find it strange to see axis values less than zero, as long as there are no data points there...

The problem is that the graphs are not making full use of the space available.

In the past I've used borders of [min-(max-min)_0.05, max+(max-min)_0.05] around the data points, and that works pretty well. For log scale, this is [min/(max/min)*0.05, max(max/min)**0.05]. How hard would it be to set these as the autoaxis defaults for jqplot?

I think we are agreeing... we just need to make the unused margins smaller. Shouldn't be too bad. I think jqplot does 10% by default, but we can probably change to 5%.
