that's nice!!! thank you... anyway, I wanted to take advantage of the Traits implementation of my app... simone 2009/1/23 eliben eli...@gmail.com: Simone Gabbriellini-3 wrote: Dear List, I have some variables I want to plot... the values of those variable change in time...

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 m...@thebrookhavengroup.com wrote: Thank you for the information. I figured out that using pylab works. I would rather use a current version. I tried to find the version you mentioned in a deb package for Ubuntu but it doesn't seem to exist. Do you know why or where can I get it? Probably there are none for the version of Ubuntu you're using but there are newer packages in Ubuntu[1]. I'm not a Ubuntu guru, but you seem to be rather old in version, I suggest, given the short release period, to keep your system up-to-date to the current version (not 8.10 I think) and there there are newer binary packages too[2].

[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?

[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.
