Hi,
I need a twinx() plot with horizontal and vertical grid lines for the
second axis, just like the usual grid for the first axis. I don't need or
want to specify the ticks manually, though!
My example code just produces horizontal lines:
import pylab
datax = pylab.arange(50)
data1 =
Hi Paul,
I've modified your suggestion a little, since I don't want a grid for the
primary axis at all -- unfortunately to no avail, i.e. no grid line at all:
import numpy
import matplotlib
matplotlib.use('agg')
import matplotlib.pyplot as plt
datax = numpy.arange(50)
data1 =
Hi,
why don't you just parse the returned string?
asdf = '3:04:02.994000'
asdf = asdf.split(':')
temp = asdf[-1].split('.')
print asdf
asdf.pop(-1)
print asdf
asdf.extend(temp)
print asdf
asdf = [int(i) for i in asdf]
print asdf
hrs,mins,secs,usecs = asdf
That should work, and you can always
Hi,
this is a known problem when working with subplots, reducing the
figure size or increasing the font size. It is like that by design but
there are workarounds.
http://old.nabble.com/Feature-request%3A-automatic-scaling-of-subplots,-margins,-etc-td31556961.html
Yes, it is a known problem, and it is by design. However, the OP has a good
point that the gallary should have nice-looking plots. Therefore, it would
make sense to modify those really bad examples with subplot_adjust() to
allow them to look better.
Very much agreed :)
Hi Karthik,
I cannot find any problem with your code. You are mixing modules a little
too much to my taste but it's not a technical problem.
Loading and saving the data works flawless here. Attached is an infile and a
modified script, please try this.

Hi,
try putting an r in front of your string:
e.g. label=r'äöü߀'
And it might help to tell your editor the used encoding, too, by
putting this as the first line:

Hope this helps,

Hi,
the content of the CSV is stored as an array after reading. You can
simply access rows and columns like in Matlab:
firstrow = a1[0]
firstcol = a1.T[0]
The .T transposes the array.
The second element of the third row would be
elem32 = a1[2][1]
which is equivalent to
elem32 = a1[2,1]

Hi,
firstly, I do not fully understand why you have chosen such a complicated

However, I don't understand why it works at all. Usually, when I apply

Hi Waléria,
in order to test it and help you without spending too much time on it,
could you please provide a stripped example which runs standalone?
As a general rule you should set limits at the very end of the
plotting code in order to prevent them from being superseded by
another command!
Hi Waléria,
you should try to figure out the docstring help :)
In a terminal (IDLE or IPython), just do

This will show you extensive help on the command.
You will also need to compare with the regular plot command:
matplotlib.plot?
