I've just had to deal with a similar problem, you need to use the
basemap.shiftgrid() method to shift the co-ordinate grid accordingly.

Hi Joshua,
As you can see from the attached graph, there is a break the in graph
somewhere around 7 AM or so. This is the data I am graphing for that red
line:
"2007-10-09 00:00:00",0.015
"2007-10-09 01:00:00",0.015
"2007-10-09 02:00:00",0.014
"2007-10-09 03:00:00",0.012

John,
I would prefer to be able to use the power and flexibility of datestr2num
and the underlying dateutil.parser, rather than writing my own parser.
However, looking further at dateutil.parser.parse, it takes an argument
tzinfos, which allows timezone names other than the local timezone and
UTC

Thats it! Thanks a lot!

I am trying to prepare a plot on the UK national grid. This is a transverse
mercator projection centred on the UK with a false origin offset from the
projection origin (lat_0, lon_0).
The Basemap coordinate system origin (0 Easting and Northing) always seems to
be set in the lower-left corner

Not sure how to answer this question vis-a-vid dateutil.p
I am having some problems getting matplotlib.dates.datestr2num to handle
timezones in the datestring.

Hi Yadin,
I am a simple user, but I already faced this problem. The idea I used is
to plot the data as an image, with magnitudes being converted in color
levels.
To do that, you have to define an array (let's say 'Z', Z(x,y) with dims
len(X) and len(Y) and fill it with tour magnitudes. Then

I i have tree lists or array of values
list x of 100... values
list y of 100.. values
list mag of 100.. values
list x and y are coordiantes of points
and list Mag is magnitude of something at that point
how can i plot this quantities using matplotlib, any function please?
my code starts as.

Teaching them what is a module and a namespace is a good think, why don't
telling them to do :

import numpy as npy

Hi,
I'm using matplotlib in a C++ app (with a qt4 gui), by embedding python with
boost::python. The C++ app calls Py_Initialize(), init_myplottingmodule(), and
boost::python::import("matplotlib.pylab") once on startup and certain GUI
events then fire up a matplotlib window via calls like this one:

I'm running into a problem using the mollweide projection, with the
following simplified code, my actual code doesn't use random data for
values but this is a clearer example to the problem I'm experiencing:
lon = numpy.arange(0, 361, 1)
lat = numpy.arange(-90, 91, 1)
x, y = numpy.meshgrid(lon

Yes, this was left in initially for backward compatibility but I think
we should strive for maximal numpy compatibi
I have successfully (I think) coerced my students into using
Scipy/Numpy for signal processing and dynamic system modeling. They
are mechanical engineering coming from a Matlab background. In order
to make using Python easy and have it feel like Matlab, I teach them
to put
