[Matplotlib-users] Subplot size
Hello, matplotlib-users. Hi! I'm using matplotlib to display dynamic graph of incoming data. Separate window with embedded graph in it. Everything okay, except of too much, or too less space available for graph data, since it passed as percentage. For my case better to say that 20px from left and 20px from bottom are for axes, everything other is graph data. Is that possible with matplotlib? Or only handle resize request and update percentage as needed? -- Best regards, Anton Call2Ru Service [EMAIL PROTECTED] pgpVk0q1YfXKT.pgp Description: PGP signature - Check out the new SourceForge.net Marketplace.

Hey James, we were discussing problems with the wx backend on 0.98 yesterday on the devel list, and Ken offered to take a look at them, so it is possible we will have those fixed for the next bugfix release. What wx version are you using? Note that unless you are running over an x11 connection, there is little reason to prefer wx over wxagg, which has better rendering and more features. Over an x11 connection, wxagg is slow because it has to pass the who bitmap over the wire, but otherwise it works great. JDH - Check out the new SourceForge.net Marketplace.

In scatter, the size often is used to convey information, and the size parameter give thes area of the circle that circumscribes the marker. In plot, he marker size is not generally intended to convey information, only that something happened here, and the size choice is usually one of aesthetics. In any case, in plot the size is radius of the circle, the side of the square or diamond. For most markers, you should be able to square the markersize to get approximate correspondence between plot and scatter. JDH - Check out the new SourceForge.net Marketplace.

This is just an error in the testing framework. Apparently you need
to upgrade to nose 0.1 to run the tests. It looks like scipy built
and installed correctly since you could import it. If you want to run
the tests, go ahead and upgrade nose, but it is not essential.

Sorry I wasn't clear. This installation page is for building a
standard set of tools (MINS - matplotlib, ipython, numpy, scipy) we
use in a course we teach on scientific computing in python.
matplotlib does not require ipython or scipy (but you'll be glad you
have them!). You can proceed with the matplotlib build instructions.

Re: [Matplotlib-users] backend_wx and 0.98.0
Sorry I'm just getting into this discussion now. The wx backend in 0.98 is almost a complete rewrite to use wx.GraphicsContext rather than the older wx.DC interface. It was no longer possible to move forward with the new rendering infrastructure with the wx.DC interface due to lack of support for polycurves. As the wx backend is one of the least used, perhaps, it hasn't seen the same amount of testing as the others and you're running into the bleeding edge. (And some of us still insert an implicit "beta" everytime we see the number 0.98... ;) Note that in my testing, the new wx backend isn't any faster than wxagg over an X11 connection, and locally it's *insanely* slow. On Linux it uses Cairo, which has the same bitmap transferring issues that Agg has. So that eliminates any advantages it may have had. Possibly if one were doing some wx.GraphicsContext rendering interleaved with matplotlib rendering it might be useful, but I doubt there's any of that in the wild. I would strongly suggest we just remove the wx backend at this point and move to wxAgg for everything. I advocated this months ago, but forgot to follow through on it ---> http://sourceforge.net/mailarchive/message.php?msg_id=4734927C.3060601%40stsci.edu Local: WxAgg: 27.5 fps Wx: 1.8 fps Wx: 16.8 fps (without clipping) Network (X11 with compression): WxAgg: 2.0 fps Wx: 1.7 fps Wx: 2.0 fps (without clipping) Cheers, Mike John Hunter wrote: > On Thu, Jun 12, 2008 at 9:21 PM, James A.

Re: [Matplotlib-users] backend_wx and 0.98.0
FWIW, I developed the new wx backend using wx 2.8.6.1, and it does currently work for me. Unfortunately, it's always hard to know how to write for a broad range of point releases for wxPython -- the documentation offers little clues about when features were added or changed.

Then it might be possible that something has changed between 2.8.4.0 (the OP wxPython version) and 2.8.6.0 (yours), although it looks like a wxWidgets difference rather than a wxPython one... Andrea.

Re: [Matplotlib-users] backend_wx and 0.98.0
Hi, Andrea. Yes, I bet that upgrading would resolve the issue. However, the issue isn't getting in my way at the moment, since I use the WXAgg backend and it works well as far as I can tell. I mainly wanted to point out for informational purposes -- and I may have been unclear about my point -- that the Enthought Python distribution is currently at wxPython 2.8.4 and that the WX backend seems not to work at that version. - Check out the new SourceForge.net Marketplace.

[Matplotlib-users] axes labels missing from plot
Hi, I'm not sure if I'm doing something wrong, but I find the sizing of the axes areas when doing plots a bit problematic. If I make the figures small, the actual plot area takes up most of the area and the axes labels aren't visible unless I make the window bigger. When I export to eps or pdf, they are also cut off. Is there a way to get the plot area scaled to the figure size in such a way that the axes labels can be included? I am trying to avoid having to scale the image when it is included in the document.

Try this: import numpy as np import matplotlib.pyplot as plt salinity = np.random.random(50) depth = np.linspace(1, 500) plt.plot(salinity, depth) ax = plt.gca() ax.set_ylim(500, 0) Things to note: 1) Matplotlib doesn't care about dependent or independent variables. With plot(x,y), one variable gets mapped to the x-axis, one gets mapped to the y-axis. 2)ax.set_ylim says that the call is (min,max), but what it really means is (lower,upper).

[Matplotlib-users] Handling data and creating arrays
Hello, I've started to use the convention of making dictionaries to hold my
datasets. But I haven't settled on an approach yet, and would like input
from people for how they a) handle their arrays of data, and b) how to
create pylab arrays from lists of lists, etc.
What I generally have is:
DataDict={var1:(x1,y1),var2:(x2,y2),var3:(x3,y3)} ; where the x and y's are
generally lists.
Now that's nice, because I can cycle through the DataDict.keys() to batch
plot, etc. But how can I convert the whole dict into a single array
(assuming the lengths are all equal)? I would like:
myArray=
x1a,y1a,x2a,y2a,x3a,y3a
x1b,y1b,x2b,y2b,x3b,y3b
...
x1,z,y1z,x2z,y2z,x3z,x3z
Where:
myArray[:,0]= x1a...x1z
myArray[0,:]=x1a,y1a,x2a,y2a,x3a,y3a
and so forth...
Thanks!

You might be able to use numpy record arrays (recarray). There are lots
of good reasons to use numpy arrays other than plotting.

Okay?? That does seem to work... I guess I'd better go read up on index_tricks.py ? Thanks.

[Matplotlib-users] Dynamically defining map extents
Hello, I've defined the following function to dynamically define map extents based on lon,lat input data. It is not very elegant or robust, but it does seem to work. One issue, however, and it probably is related to something else further down the chain... but every plot ends up being a different size. So an improvement right off would be able to define a plot size (or at least ratio, such that the limits would scale to the ratio). I would be interested in comments on how to improve it. def map_dynaMap((x,y)): """Sets a map region based on input data """ ymin=min(y); ymax=max(y); y_edge=abs(ymax-ymin)*0.35 xmin=min(x); xmax=max(x); x_edge=abs(xmax-xmin)*0.35 llcrnrlat= ymin-y_edge if llcrnrlat<-90.: llcrnrlat=-90. llcrnrlon= xmin-x_edge if llcrnrlon<-180.: llcrnrlon=-180. urcrnrlat= ymax+y_edge if urcrnrlat>90.: urcrnrlat=90. urcrnrlon= xmax+x_edge if urcrnrlon>180.: urcrnrlon=180. area_thresh=1000 resolution='l' projection='aea' lat_0=y[int(len(y)/2)] lat_1=lat_0-y_edge lon_0=x[int(len(x)/2)] #lon_1=110. rsphere=(6378137.00,6356752.3142) pd=y_edge md=x_edge return urcrnrlon,urcrnrlat,llcrnrlat,llcrnrlon,pd,md,lat_0,lat_1,lon_0,area_thresh,projection,resolution,rsphere -- View this message in context: http://www.nabble.com/Dynamically-defining-map-extents-tp17835230p17835230.html Sent from the matplotlib - users mailing list archive at Nabble.com. - Check out the new SourceForge.net Marketplace.
