[Matplotlib-users] problems with errorbar upper/lower limits

I'm plotting upper and lower limits via the lolims and uplims keywords to the errorbar function and have noticed two problems. First, the direction of the arrows produced by these keywords are opposite to one would expect, i.e. lolims=True should produce an upward-pointing arrow and uplims should

You can pass "extent=(left, right, bottom, top)" to imshow to specify what the pixels in the array correspond to in data space. Mike Lewis, Ambrose J. wrote: > > Hi All: > > I’m working on a wxPython GUI that uses matplotlib. > > This program reads “chunks” of a data file into a numpy array and

[Matplotlib-users] quiver and Inf values

A student of mine recently noticed that sometimes, quiver plots were coming up empty (using the plot_vector_field function from Sage, which passes everything on to quiver). Upon investigation, we saw that some of the array entries passed in were infinity because of where we happened to evalua

[Matplotlib-users] x axis & imshow...

Hi All: I'm working on a wxPython GUI that uses matplotlib. This program reads "chunks" of a data file into a numpy array and than plots it using imshow. The first chunk works great. But, when I load chunks 2 to N, how can I specify the different values for the labels on the x axis? I trie

[Matplotlib-users] Issues with time display

Hi, I've managed to take the contents of my CSV file and display it with matplotlib. I'm having some issues with the way my X-axis is being displayed. For the X-axis, I pass in a list that filled with datetime objects, an example of one element on the list: datetime.datetime(2007, 12, 17, 20, 2

[Matplotlib-users] problem in cbook.py

Hi, I am not expert in matplotlib, I use it to generate plots for a management performance tool. I have just upgraded this application from 0.98.3 to 0.98.5 and the upgrade broke the application in 3 places: 1). In units.py, Registry.get_converter(): this method has been made recursive in
