Re: [Matplotlib-users] Basemap/ orthographic projection plot doesn't respect globe boundary
Hey Jeff, It's somewhere between the two - the original satellite swath is converted to a regular 0.5 degree grid by truncating, binning, and averaging each point's lons and lats over the top of a 720 x 360 np.zeros array. the plotting still works fine for non ortho/ hemispherical projections, and I've no big problem with using global projections for the time being. Thanks for your help in the meantime anyway. Cheers, Will. Jeff Whitaker wrote: On 4/4/10 11:06 AM, Will Hewson wrote: Hi again Jeff et al...

Re: [Matplotlib-users] Basemap/ orthographic projection plot doesn't respect globe boundary
I should perhaps of explained my code (included in top post) a little better, the values in my attached file aren't on a regular grid to start with, I do a little bit of juggling as follows to get them into a regular grid: I'm firstly setting up my 2D grid of 0.5 degree lat lons, followed by identically sized grids of zeros for the data bin, and mean divisors: x = np.arange(-180, 180, 0.5); y = np.arange(-90, 90, 0.5) grid_lon, grid_lat = np.meshgrid(x,y) #regularly spaced 2D grid n_vals = np.zeros((360,720)) #mean divisor dat = np.zeros((360,720)) #2D grid of zeros I'm then taking my input data (e.g. the .plt file attached), and rounding the lat lons to the nearest 0 or 0.5: lon = (np.around(lon*2))/2 #round to nearest .0 or 0.5 lat = (np.around(lat*2))/2 #round to nearest .0 or 0.5 Then for each row in my input file where Z is greater than 0, I'm adding the n'th Z value to its corresponding position in the dat zeros array, and keeping a count of how many values are going into each cell in the mean divisor array: j=0 for i in slcol: if lon[j] 0: grid_lon_ind = 360+(lon[j]*2) grid_lat_ind = 180+(lat[j]*2) else: grid_lon_ind = 360-(lon[j]*2) grid_lat_ind = 180+(lat[j]*2) if i 0: dat[grid_lat_ind, grid_lon_ind] += i #add i'th value n_vals[grid_lat_ind, grid_lon_ind] += 1 #increase cell counter by 1 for each extra value j+=1 Finally the new dat array is divided by the mean divisor array to give me my mean Z values: dat = np.nan_to_num(dat/n_vals) I've done it this way as opposed to interpolating *properly* in order to (for instance) stop the values bleeding away from the edges of the satellite swath.

Re: [Matplotlib-users] speed up imports?
All of those calls to open are being generated from the pytz import --
which is why pytz seems like the likely candidate. Is it possible you
have pytz installed as a compressed egg, or on a remote disk, or
something that may be causing a file reading penalty?
As Eric said, make sure you time the import pytz in a clean Python
session -- if a module is already imported in the Python interpreter, it
won't be reimported.

This change removed a commented out call to ps2eps. I'm a bit out of my depth here as to why that change was made, and why .eps files seemingly haven't been true .eps files for a long time prior to that change. Anyone else? To my best knowledge, the bbox of the eps output before r8102 was incorrect for some cases. r8102 was my attempt to fix some of the issues. The ps backend is quite complicated in how final output is produced (psfrag, distiller, pstoeps), and this often messes up the initially specified bbox and results in incorrect ones. While I think I fixed some of the issues, there still could be some left. And I hope someone who is more knowledgeable than me take a look. For the reported issue, I haven't take a time to investigate (but I will soon), but I doubt if it is an issue of pstoeps function (as I said, it seems to write a matching save-restore pair).

Re: [Matplotlib-users] speed up imports?
Michael Droettboom wrote: All of those calls to open are being generated from the pytz import -- which is why pytz seems like the likely candidate. Is it possible you have pytz installed as a compressed egg, or on a remote disk, or something that may be causing a file reading penalty? Mike, The pytz import time, at nearly 1/3 of the total mpl import time, is crazy even on linux, given that it adds only a tiny bit of functionality, and as far as I can see, even that is only rarely used. Therefore I have committed a change so that it is imported only if and when it is required. Our examples still work, after I modified one that was trying to import timezone from mpl.dates (although it was not actually using timezone). This probably illustrates the way in which this change may break some user code: user programs requiring pytz.timezone and pytz.tzinfo will have to import them directly instead of getting them from mpl.dates. I hope this is acceptable; importing them from mpl.dates seems like bad practice anyway, since mpl.dates was not using them or modifying them but was just passing them on from pytz. I suspect pytz could be redesigned so that it would not be so horrendously slow to import, but I am not going to tackle that. After the change: efir...@manini:~$ time python -c import pylab real0m0.441s user0m0.372s sys 0m0.064s Before the change: efir...@manini:~$ time python -c import pylab real0m0.626s user0m0.480s sys0m0.124s Again, this is recent linux on a 3-year-old laptop. Eric As Eric said, make sure you time the import pytz in a clean Python session -- if a module is already imported in the Python interpreter, it won't be reimported.

I know I am abusing the term sparkline because I am not embedding the visualization within text, but I am not sure what else to call it. I do think that showing the time series not bound within a set of axes, without labels, underscores that the time series is a quick hit, just like the histograms are.
