[Matplotlib-users] draggable annotation bug and fix

2011-09-15 Thread Daniel Hyams
There seems to be a problem with the draggable annotation code when the annotation is just clicked, and not dragged. If you run the following code: import matplotlib.pyplot as plt fig = plt.figure() ax = fig.add_subplot(111) ann = ax.annotate('local max', xy=(2, 1), xytext=(3, 1.5),arrowprops=dic

Hi, On SUSE you have "zypper" I'm not familiar with SUSE repos, but OpenSUSE repos do have matplotlib, just type: "sudo zypper in python-matplolib" that should install it for you. -Filipe On Thu, Sep 15, 2011 at 14:22, John Hunter wrote: > On Thu, Sep 15, 2011 at 11:42 AM, falbriard wrote

I was able to confirm this bug with 1.0.1, but it has already been fixed in git master. This fix should make it into the next release. I used "git bisect" to track down the point at which it was fixed and turned up this: https://github.com/matplotlib/matplotlib/commit/6fe5fa03e8608949cb08a

I wouldn't recommend trying to build freetype from source. Have you installed the freetype development package? I'm not familiar with SuSE, but on RedHat/Fedora this would be accomplished by (as root) "yum install freetype2-dev" and on Debian/Ubuntu "apt-get install freetype2-devel". Mike O
