Re: [Matplotlib-users] Quiver plot of a netcdf file

Okay, so in the "variables" section, what you've got is a list of things which vary as a function of the "dimensions" listed in the previous section (time, nsr_delta, lat, lon). I don't remember which of the NetCDF file reading libraries you're using, but using Jeff's older netCDF3 interface, you

Re: [Matplotlib-users] Quiver plot of a netcdf file

Thanks for the suggestion to look at the demo, I had missed it in my initial look through. The quiver_demo seems to be broken up into three sections. The first section initializes the information for the the two quiver plots (sections two and three). This seems like the logical place to start for

Hello, Now that I have correctly imported the NetCDF file and set up the kind of projection I am interested in having the data displayed over I am having trouble plotting my data with the quiver function. I am interested in plotting the principal vectors of the stress field onto a Mercator proje

Re: [Matplotlib-users] Quiver plot of a netcdf file

Hello, First let me say thank you for all of the help it is very appreciated. Your suggestion to use the command import "import mpl_toolkits.basemap" has worked, but now a new problem has popped up. Does the Netcdf file need to be in the same directory as the script I am running to retrieve th

Re: [Matplotlib-users] Quiver plot of a netcdf file

The suggestion to install matplotlib.basemap seems to be the right direction to go. However, I have been unsuccessful in importing the file by this method. This is what I have been trying. from mpl_toolkits.basemap import Basemap import numpy as np import matplotlib.pyplot as plt import matplotl

Re: [Matplotlib-users] Quiver plot of a netcdf file

I was under the impression that ScientificPython.io.netCDF was outdated. I have no preference on ncdump and if there is an easier way to import the data, then I am all for it. Right now the pupynere website is down so I can't check the site for help. Thanks for the responses. Paul Anton Letne

Re: [Matplotlib-users] Quiver plot of a netcdf file

In addition to scipy.io, there are some pure python netcdf readers, including pupynere (might be easier to install a pure python module?). Also, you have ScientificPython.io.netCDF, in case this is more convenient for you. ncdump is almost certainly not the way to go, it is best suited for human in

Hello, I am trying to use matplotlib to create a quiver plot of a NetCDF file with the extension .nc. The Netcdf file is a series of arrays that contain information about the stress tensors on a globe. I am struggling to import the file into python and having the quiver data show up. To import th
