Couldn't see the answers to these questions when looking through the class reference docs, but they seem like common tasks, so I suspect there are standard idiomatic way of doing these. Could anyone refer me to examples showing 1) How to most easily label the x axis for data which is plotted by date? (More specifically; does matplotlib have any understanding of date values, and if so, how do I access and use it?) I'm hoping there's an easier way than explicitly labelling ticks on the x axis. 2) I'll be drawing logy graphs, and I want a certain slope to indicate a certain rate of growth, which means that, when using matplotlib via TkAgg, I want it to keep the ratio of the graph display height and display width constant as it resizes the graph to take into account changes in the size of the enclosing window. Is there a standard way to do this? Thanks, Ken McDonald |

Is there a Kenneth> standard way to do this? This is a good idea but it's not implemented and should be. How do you think the best way is to indicate a constrained resize? With a modifier key held down during the resize? JDH |
