[Matplotlib-users] No output when using webagg backend

I'm trying to use the webagg backend for the first time, and seem to be bumping into a common problem - nothing appears. The first time I tried, I got a complaint that tornado was missing, so I installed it. After that, I get to try plotting. Here's my example: >>> import matplotlib >>> matplotlib

[Matplotlib-users] Matplotlib interactive shortcuts?

I'm happy with the draggable legends, but I have a problem. It seems there are three pointer modes, the initial mode (updates x, y as you move the mouse), zoom rectangle mode, and pan/zoom mode. Once I enter either of those modes, I can't see how to get back to the original mode. I found this navig

[Matplotlib-users] Interative legend manipulation?

Sometimes the legend simply gets in the way. You can't always guess the correct placement (think generic tool which processes lots of different input data sets), or zooming/panning makes it obscure a chunk of the plot you want to look at. Is it possible to move it interactively? I'm using mpl 1.3.1

[Matplotlib-users] Question about backends and X

I have a matplotlib application which can display a plot or write it to a file based on command line flags. I have discovered that if it is run without DISPLAY set (say, from a crontab file) that the default backend (I have no matplotlibrc file) attempts to chat with X, causing crashes. I've worked

At work both mpl 1.1 and mpl 1.2 are installed. (I have no idea why.) Vagaries of our current packaging cause problems (import finds 1.1 before 1.2 in sys.path). The question was what to do. I took a look at the latest What's New document and concluded that removing 1.1 would be the best route. In

[Matplotlib-users] Problems using Matplotlib from a GTK app

I want to use matplotlib as a component of a larger, event-driven GTK app. That means pylab.show is (I think) not the way to go, as it starts up its own event loop which doesn't return. I've tried to clear and plot in my event handler, but my plot is never displayed. My initialization code looks l

Let me return to my FuncFormatter usage. As I indicated in an earlier post, I made a single format decision based on the x range of the entire data set. The decision code was straightforward: x_delta = x_range[1] - x_range[0] if x_delta > int(1.5 * 365) * ONE_DAY: xfmt = "%Y-%m-%
