[Matplotlib-users] Colorbar labels never appear vertically

[Matplotlib-users] Bug in scatter

Re: [Matplotlib-users] Colorbar labels never appear vertically
After some testing, it appears to be caused by the use of LaTeX in the labels which then prevents it from being rotated (but only inside the GTK application). I have no idea why this is only occurring when it is not in interactive mode, but I guess for the time being I can just try not to use LaTeX.

[Matplotlib-users] Define minimum precision for tick labels
Hi, I have a minor style problem, but, nevertheless, I can't solve it with googles help. I want to have a minimum precision displayed on my ticks, i.e. if the ticks are -1,-0.5,0,0.5,1 it should be displayed this way instead of -1.0,-0.5,0.0,0.5,1.0. With the tick formatter I can set the tick precission, but only for the whole axis (if I set %d for the example, it will be -1,0,0,0,1). Also I use MaxNLocator, so I don't predefine the ticks (I thought it's more convinient to use this already done procedure instead of writing my own), so I'm more flexible, for example when I zoom in, but therefore I don't even know, which the maximum precision is. Possible solutions would be: 1. There is a number precision definition (something like %x.xf) which produces numbers with minimum precision (again -1. becomes -1 and 2.47300 becomes 2.473) 2. Extract by MaxNLocator defined ticks, edit them accordingly and reassign them (which would be still a lot of work) I even checked for solutions in Latex (because I use Latex string coding), but this is even more inflexible, when it comes to numbers. But maybe someone knows anything. Thanks! Best regards, André -- Get a FREE DOWNLOAD! and learn more about uberSVN rich system, user administration capabilities and model configuration.

Depending on the range of your values, %g might do want you want. E.g.:

from matplotlib.pyplot import plot, show, gca
from matplotlib.ticker import FormatStrFormatter
majorFormatter = FormatStrFormatter('%g')
t = linspace(-1.0, 1.0, 41)
s = sin(2*pi*t)
plot(t,s)
ax = gca()
ax.xaxis.set_major_formatter(majorFormatter)
show()

[Matplotlib-users] Symmetrical Log Scale on Axis
Hi,
I am having some trouble establishing how to use
matplotlib.scale.SymmetricalLogScale() to draw a log scale on the positive
and negative axis of a plot. Assuming of course that is the correct way to
go about it
The code at the moment I am looking at goes something like this, with
arbitrary data generated. I need SubplotHost for parasite axis later on.
import matplotlib
import pylab
import numpy
from mpl_toolkits.axes_grid.parasite_axes import SubplotHost
fig = pylab.figure(1)
main = SubplotHost(fig,111)
fig.add_subplot(main)
x,y = []
for i in range(100):
y.append(numpy.random.rand())
y.append(-numpy.random.rand())
y.append(numpy.random.rand() * 100)
y.append(-numpy.random.rand() * 100)
x = range(len(y))
main.plot(x,y)
At this point I was expecting to be able to run with SymmetricalLogScale in
the same way main.set_yscale('log') transforms after the plot but could not
work out how to transform it other than:
main.yaxis = matplotlib.scale.SymmetricalLogScale(main.yaxis)
But that obviously didnt work, since SymmetricalLogScale doesnt have
get_scale
If anyone could shed some light on the way to invoke this I'd be much
obliged!? I havent been able to find an example of it's usage anywhere
Cheers
Jonny

Re: [Matplotlib-users] Bug in scatter

(I suspect it is a malign side-effect of some attempt to make bar plots work with a log scale, but I haven't tracked it down.) What is less clear is the desired behavior. Raise an exception? Silently delete the points that are invalid with a log scale? Or delete them with a warning? I would delete them with a warning. Those who are familiar with logs will not be surprised. Those who are not familiar will be provided an opportunity to learn something new! I have tracked down the problem, and am testing a fix for it. The intended behavior was silent masking of non-positive values. An option for a warning could be added, but for now I will just make it work as intended, and as it does with other plot types.

Re: [Matplotlib-users] How to set the data for an existing pcolormesh image?

For normal plots, there is a set_xdata/set_ydata methods. For QuadMesh, there is a set_array method, which i don't get to work. You have to use ravel().

[Matplotlib-users] Can I change pixel aspect with axes_grid
Usually imshow(arr, aspect='auto') or imshow(arr, aspect=2.0) will display the image with pixels having some aspect ratio other than 1:1 However, I cannot get this to work when using imshow within an AxesGrid axis. Is there a way to get an array shown with imshow() within an AxesGrid axis to have a pixel aspect other than 1:1 ? If not, is there a simple way to add a shared colorbar when using subplots() ?
