[Matplotlib-users] Looking for additional help about moving a legend
Hi all, Forgive me as this is the first time I've posted here. I've asked a question on StackOverFlow: http://stackoverflow.com/questions/10101700/moving-matplotlib-legend-outside-of-the-axis-makes-it-cutoff-by-the-figure-box#comment12952803_10101700 The question relates to adjusting the size of the figure box to accommodate a large legend when the legend is placed below instead of on top of the axes. I thought I'd post here to see if there are any other answers to avoiding having the figure box cut off the bottom of the legend. Thanks Jonathan -- There are no passengers on Spaceship Earth.

Best /Chris Hi Mike, A follow-up question... When using that, if one then tries to manually use the zoom-box tool available with a matplotlib plot, if one draws too small of a box (less than 2 major ticks in x or y dimension, based on the following error message), it gives the following error and further operations on the plot do not work. ValueError: Need at least two major ticks to find minor tick locations ( File /usr/lib/pymodules/python2.7/matplotlib/ticker.py, line 1528, in __call__ ) Any way to avoid this for now? (And ultimately, should this be made into a bug fix request?) Ok, I seem to remember seeing this error before, but I can't trip it now (with either 1.1.1rc or today's git checkout of 1.2.x). Do you have a short script that can reproduce this? For me, the zoom-box tool seems to be [correctly] setting the majortick locations as I zoom in, thus preventing this exception. I should note that I'm using the GTKAgg frontend. This may be the issue. A long time ago I was using the MacOSX frontend, and maybe this was when I was seeing it... Aside from that, this would be a bug. M On Wed, Mar 28, 2012 at 10:50 PM, Christopher Graves christoph.gra...@gmail.com wrote: Hi Mike, Ok I found the root cause.

Is there another way to fix the x and y tick interval as equal? (And ideally even maintain the equal spacing when zooming..
