matplotlib-users Mailing List for matplotlib

Sorry for the delay.
I don't know if I ever included my software versions:
Python & IDLE 2.6.2
matplotlib 0.99.0
numpy 1.4.0rc1 (I was using 1.3.0)
Here is more complete code. This is the only place I use matplotlib for
anything so I don't think any earlier code should affect the plot.
I've included the values of the input variables below and I could include
all the code which gets the data and manipulates it if this would help.

y_dim, water depths in meters, is:

in the example plot below z_dim is a dictionary with three arrays,
'do','chl','turb'.
as an example, z_dim['chl'] (chlorophyl) is a 2D array of the form:

Here's the plot as it stands now:

Good morning list,

I have been trying to install the latest matplotlib on Snow Leopard
with the latest X-Code for a few days.  I have tried the installer
packages (wrong versions) and the source (build errors) and neither
worked.  I finally got it installed correctly by using MacPorts.  I
wrote up what I did in case anyone else is having issues installing on
Snow Leopard [1].

Cheers,

Daniel

Hi:

I'm trying to get a semilog 3D plot. I want to plot several 2D time series
lines, with the third axis being on a log scale. I am trying to set an axis
to log using ax.set_yscale('log'), but am getting errors. Is this possible?

I keep getting numpy errors when I try:
raise MaskError, 'Cannot convert masked element to a Python int.'
numpy.ma.core.MaskError: Cannot convert masked element to a Python int.

My attempt:

from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np

fig = plt.figure()
#ax = fig.gca()
ax = Axes3D(fig)

colors = ('r', 'g', 'b', 'k')
zd = (0., 1., 2., 3.)
T2 = (0.9, .8, .7, .6)
ic = 1

for ic in xrange(len(colors)):
    x = np.arange(0.05,1,.005)
    z = np.exp(-x/T2[ic]) + np.random.normal(0, .05, len(x))
    y = np.exp(zd[ic])*np.ones(len(x))
    ax.plot(x,y,z)

# Error if uncommented
#ax.set_yscale('log')
plt.show()

Thanks for any insight.

I found the solution with some tinkering. Basically, I needed to grab the
transformation of the labels.
    tx = ax.get_xticklabels()[0]
    text(1.5,  0.0, "some text", transform=tx.get_transform())

To also get a constant offset:
    text(1.5,  0.0, "some text", transform=tx.get_transform() +
ScaledTransformation(-.1,-.1, fig.dpi_scale_trans))

Abhi

Hu Jae-Joon,
Yes this is very useful, I thinks many people here will love this.

I tried to access the code, but I could not get there.

Can u pass me the link.

Not that I know of.

By the way, in case you haven't set it up a shortcut to Console that 
starts up IPython, I did it like this:

I created a shortcut to console in my start menu:

Properties|Shortcut
Target: "C:\Program Files\Console2\Console.exe"
Start in: "C:\Program Files\Console2"

Then in Console, under Edit|Settings|Tabs

Create a tab with
Main|Title & icon|Title: iPython
Shell|Shell: C:\PYTHON25\Scripts\ipython.exe -pylab -wthread -p pylab
Shell|Startup dir: C:\Python25

Did you mean "Reply All"?

Some of us would appreciate it if people just responded to the list and not 
including our individual addresses at all. With very rare exceptions, everyone 
who posts is already on the list. I subscribe to the list via the GMane NNTP 
interface and hate receiving private-looking (hence urgent-looking) replies in 
my inbox.

The default "Reply To" on this list is set to go to the original
poster. It's a setting in the mailing list software, not anyone's
e-mail client.

If you post a question and someone responds using "Reply To", then
their response will go directly to you. If they respond using "Reply
To All" (as I have here) then the e-mail is copied to the list address
as well.

The moral? Always use "Reply To", and hope everyone else remembers to
do so as well :)

Add a kwarg to your formatter initialization.  See below.

Hao,

I ran your code and got this (see attached). I don't get the 'e' that you mention, but a 'times' symbol instead.

My rcParams are such that the entire figure is sent to LaTeX. Not sure if that changes things.

Good luck
-Paul

Hi there:

I tried to plot large numbers and scientific notation has to be used.
But instead of "\times" symbol, it used "e", which cannot be accepted as
publishable. Anyone know how to deal with that?

My original code is:
####################################################
import matplotlib.pyplot as plt
import numpy as np
from matplotlib.ticker import ScalarFormatter

# data generation
x = np.arange(1,1e3,20)
y = x**2

formatter = ScalarFormatter()
formatter.set_scientific(True)
formatter.set_powerlimits((-3,3))

fig = plt.figure()
ax = fig.add_subplot(111)
ax.xaxis.set_major_formatter(formatter)
ax.yaxis.set_major_formatter(formatter)
ax.plot(x,y)

plt.show()

####################################################

I thought the console was the only way to use IPython. I go to 
Start->Allprograms->IPython, and select IPython. Oh, I see *Console" is 
something of a replacement for the Win Cmd Console. Is there some site 
that shows off it's features?

OK, here I go. Quick Edit is checked, and I'm running from what looks 
like the Win XP command console. I am not in full screen mode. I've 
applied changes to the window. It has scroll bars side and bottom. I've 
moused the area, and now am going to Edit on the window menu. It works!  
I just pasted it into a txt file. Thanks. Pretty convoluted, but it works.

Is it possible to paste from outside? For example copy and paste from a 
txt file.
