Excellent, thank you. That works for both quiver and barb. In regards to the shape that has to do with the netcdf file, wind direction variable also has lat and lon. I ended up needing to slice so I could skip a few points otherwise there was too many arrows on the map. Below is the code that worke

Mike, You may want to look into the matplotlib.cm and matplotlib.colors modules. I've had good success with matplotlib.colors.LinearSegmentedColormap and its 'from_list' method. The documentation is the best location for information on this topic. If you have a large number of locations, then the

Anon, I don't know the quiver routine, but u and v are usually vectors for the wind speed in the east-west and north south directions. As such they should not be equal to lat and lon (*10), as you are doing, but rather should be windspeed * sin(direction) and windspeed*cos(direction). If you

For those interested things are defined differently. ax.axis["bottom"].major_ticklabels.set_pad(10) ax.axis["bottom"].label.set_pad(15) ax.axis["bottom"].major_ticklabels.set_rotation(30) explained well here (http://matplotlib.sourceforge.net/mpl_toolkits/axes_grid/users/axisartist.html#axisarti

[Matplotlib-users] rotating x tick labels, bold labels with axislines toolkit???

2011-10-04 Thread mdekauwe
Hi, I can't seem to combine the ability to rotate labels and make labels bold when I use the axislines toolkit (http://matplotlib.sourceforge.net/mpl_toolkits/axes_grid/users/axislines.html). Is there a way to make this work? e.g. the below script does not rotate the xtick labels or make the la

Re: [Matplotlib-users] plot arrows for wind direction (degrees)

2011-10-04 Thread questions anon
Thanks for responding. I believe quiver is more appropriate because I am only using wind direction (at this stage) and this results in arrows. I have had a look at the demos and still do not understand how to plot my degrees in arrows. How do I define which angle is north, south, west, east, etc? A

Ryan, I should clarify my color issue. Your code is smart enough to generate however many colors are needed but I want to make sure the colors are all unique. Thanks again! Mike Mike, sorry to send this twice... I should have sent it to the list as well... ___ Mike,

Ryan, I have tried setting c=locations (after converting to float) and gotten inconsistent results. For a dataset with ~32,000 points it seems to work, but a 2nd dataset of ~100,000 points colors everything the same even though there are at least 10 locations. Your second idea works nicely and I'm

Hi Nils. I have never tried to do a real printout, so I am no expert here. My use case was almost always to directly create pdf or ps documents, which can be done nicely using the several print_* methods of the figurecanvas. You can use Actions for your case instead of a widget. Actually they s

Hi Nils. The Qt based Navigation toolbar is just a Qt Widget with a proper layout already set. So you should be able to add any Qt widget to the toolbar using its addWidget method. I was able to add a simple line edit (without any use) like so: import sys from PyQt4.QtCore import * from PyQt4.Q
