[Matplotlib-users] Safe SVN version
Hello all, I am at a Sage days workshop and one of my goals is to update matplotlib in Sage. We want to pull from SVN since there are some (very *nice*) arrow-drawing features only in SVN. Is there any recent commit points that we want to avoid because of stability? If not, we'll probably update to the most recent svn version, which I'm pulling right now.

[Matplotlib-users] plotting a circle in log space
I have discovered, from the mailing list, the easy way to draw a circle
in linear space:
cx = 700
cy = 700
r = 1000
xmin = cx - r
xmax = cx + r
ymin = cy - r
ymax = cy + r
cir = Circle( (cx,cx), radius=r,facecolor='w',edgecolor='b')
a = gca()
a.add_patch(cir)
axis([xmin,xmax,ymin,ymax])
axis('equal')
However, when trying to overplot a circle on an existing log/log plot, I
get a circle section:
e =
[70,1,1,12,7,185,6,3,0,1015,6,222,500,0,661,105,0,8706,0,23,131,0,0,0,6,22,1,4,0]
o =
[180,2,0,15,13,3,0,0,0,20,6,2000,9748,0,38,100,0,20023,0,2,0,0,0,0,1,0,0,0,1]
f1 = figure()
loglog(o,e,'b.')
hold('on')
cx = 700
cy = 700
r = 1000
xmin = cx - r
xmax = cx + r
ymin = cy - r
ymax = cy + r
cir = Circle( (cx,cx), radius=r,facecolor='w',edgecolor='b')
a = gca()
a.add_patch(cir)
axis([xmin,xmax,ymin,ymax])
axis('equal')
How can I plot a circle in log space?
As an additional aside, I've discovered that even if I define the points
that make up a circle (in linear space), I cannot plot a smooth line
through them using the plot() function:
def pol2cart(th,r):
x = r*cos(th)
y = r*sin(th)
return (x,y)
def drawCircle(cx,cy,radius,np,style):
theta = linspace(0,2*pi,np)
rho = ones((1,np))*radius
x,y = pol2cart(theta,rho)
x = x + cx
y = y + cy
plot(x,y,style)
cx = 700
cy = 700
r = 1000
drawCircle(cx,cy,r,1000,'b')
When I look at the resulting plot, I see empty axes. If I change the
plot style to 'b.', then I see the circle. Is this a bug or an
undocumented feature?
Thanks,
Mike Hearne

Re: [Matplotlib-users] ImportError: No module named pyplot
Thank you. I finally upgraded my Ubuntu system, pretty easy, and now pylab is available. Thank you to everyone on this thread for your input. BTW, matplotlib is very nicely done, useful, and appreciated. Marc Sandro Tosi-4 wrote: > > On Wed, Jan 21, 2009 at 15:01, mzs wrote: >> >> Thank you for the information.

This is because there is no docstring for show() in pyplot.py, because it gets pulled in from the backend. Any idea how to fix this? Show() really needs to be in this list, seeing as it's the most important line in any script. I'll also add that pyplot.plotting() shows up on the pyplot.api page completely busted. Seeing as this is a dummy function whose sole purpose is to hold a docstring listing plotting functions, is there something better we could do here? Could we put the information in the plotting docstring as a pyplot module level docstring and do away with plotting() all together? > At _http://matplotlib.sourceforge.net/users/shell.html_, there are two > typos: "opertation" and "on every plot commands". > > At _http://matplotlib.sourceforge.net/users/shell.html_, the link > :_file:matplotlibrc_ does not work (unless the user has a /matplotlibrc > file). Fix these two. Thanks for the reports!

[Matplotlib-users] documentation errors
At http://matplotlib.sourceforge.net/, the "Show Source" link doesn't work. At http://matplotlib.sourceforge.net/, the table of functions links "show" to http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot. show, but there is no such function mentioned there. At http://matplotlib.sourceforge.net/users/shell.html, there are two typos: "opertation" and "on every plot commands". At http://matplotlib.sourceforge.net/users/shell.html, the link :file:matplotlibrc does not work (unless the user has a /matplotlibrc file).
