Re: [Matplotlib-users] TypeError: unsupported operand type(s) for +: 'NoneType' and 'float' on 1.2.1
Greetings all,
I have this problem now as well. I use a Mac with Canopy installed and it was
working fine until I recently updated my packages and got the new matplotlib.
The code which reproduces this error for me is very simple:
{{{
x = scipy.random.normal(0,1,100)
f = figure(num=1)
f.clear()
ax = f.add_subplot(111)
ns,bns,plt0 = ax.hist(x,bins=10,log=True)
plt1 = ax.bar(bns[0:-1],ns,width=bns[1:]-bns[0:-1],color='r',log=True)
draw()
}}}
The code works fine if one comments out the ax.bar usage but fails otherwise. I
have tried multiple different kwargs or removing the second log=True and all
result in the same TypeError.
Regards,
Brian

Can you please provide a complete, minimal and self-contained script

[Matplotlib-users] Asking for help modifying a matplot windrose graphic using Python (:
Hello guys. I'm having a problem with a matplot graphic and I guess it can be easy for Python experts to solve. Hope I'm not out of topic here. Basically, I'm using this code... http://matplotlib.org/examples/pylab_examples/polar_bar.html ... but I want to turn it in something like this graphic over here... http://www.weathersa.co.za/web/images/articles/windrose.png You see, where more than one bar pointing the same direction will be put one over the other (the biggest in the base and the smallest at the top). I assumed I had to put some function at this part of the code: bars = ax.bar(theta, radii, width=width, bottom=0.0) Turning Bottom into a function call somewhat related to the radii (bar size) if both bars have the same theta (angle). Point is I'm having some trouble doing that. I'm totally stuck, actually. If not a complete solution, some tip would be apreciated.

[Matplotlib-users] mixed color dashes
Hello List, I want to make dashes that alternate in color, red, white, blue. Or black, yellow, red, etc. I thought I could overlay different dashes (first draw the black, then the yellow then the red dashes), but the 'dashes' command always starts with a colored dash. What I need is the opposite, start with a blank, then a dash. Or have an offset of xx points and then start the dashed line. Does matplotlib have such a feature? Thanks, Mark -- See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
