Re: [Matplotlib-users] Axes3d have improved handling of label placement yet
On Sun, Jul 28, 2013 at 7:14 AM, Jeffrey Spencer jeffspenc...@gmail.comwrote: Ben, Thanks that works great and also one more question. If you look at the previous example. I have noticed that at the angle the figure is at the ticklabels look like they are at the center of the grid boxes. This is not the case because if you turn it to the side as the example below image.pdf. The 0.00, 0.05 on the I_lw axis are supposed to be at the actual tick marks. Thus, can the axis be manually moved too? This isn't a huge deal but I was just wondering if it was possible to offset the ticklabels. I looked in the _axinfo but looks like for ticklabel their is only a space_factor parameter. Cheers, Jeff The effect you are seeing is that the tick labels are set to be below and in front of the tick marks. More specifically, what happens is that the ticklabels (and the axis label) are offsetted away from the center of the domain. The space_factor value you found is just some empirical value that I have found to work fairly well. Effectively, there is only a radial-like control over the spacing, not a finer-grained control. That being said, you can modify the va value of the _axinfo to control the vertical allignment of the labels. I would wonder if messing around with that might have some desired impact. Another possibility is to use '\n' characters before or after the main text for the label to make an apparent shift. Just some ideas to play around with. Cheers!

Re: [Matplotlib-users] Axes3d have improved handling of label placement yet
Jeffrey, Sorry if the documentation is a bit vague on the _axinfo front. It was intentionally done that way to keep the number of people dependent upon that kludge down. It was created as an improvement upon the previous hard-coded constants that completely prevented anybody from making any customizations at all. The spacing of tick labels for an axis can be modified like so: ax.xaxis._axinfo['ticklabel']['space_factor'] = 0.7 # This is the default value. Make it less to bring it closer to the axis and for the axis label: ax.xaxis._axinfo['label']['space_factor'] = 1.6 # Again, this is the default value. Make it larger to move it away from the axis I hope that helps!

Re: [Matplotlib-users] Axes3D rotation not working when embedded in backend
One more note about Axes3D and mouse rotation. Axes3D disconnects the mouse
callbacks when cla() is called. Which means that if you do this:
self.axes = Axes3D(self.figure)
self.axes.scatter(xs, ys, zs)
self.axes.cla()
self.axes.scatter(xs, ys, zs)
then the plot will have no mouse rotation. To fix this, mouse_init() should be
called after cla(). Currently, all of this is undocumented. Is disconnecting
mouse callbacks on cla() the preferred matplotlib way to do things? Is it safe
to *not* disconnect mouse callbacks on cla()? Maybe there is another type of
destructor that is more appropriate for this?
Thanks,
-Ben

Re: [Matplotlib-users] Axes3D labels
I'm not an axes3d expert and below is from my quick at the code, so there may be better ways. axes3d have w_[xyz]axis attributes, which are responsible for drawing tick, ticklables, and you need to change these to change ticks, etc. While, I think something like w_xaxis.set_ticks should work, currently it fails, which I think is a bug. As a workaround, you have to directly set the ticklocator. For example, ax.xaxis.set_ticks([-20, 0, 20]) becomes from matplotlib.ticker import FixedLocator locator = FixedLocator([-20, 0, 20]) ax.w_xaxis.set_major_locator(locator) -JJ On Tue, Oct 6, 2009 at 7:07 AM, William Hall w...@qualtersystems.com wrote: Does anyone know if it possible to annotate the axes with strings?

Re: [Matplotlib-users] Axes3D - size of the Z axe
Hello After search in google, I found a solution changing the initial point of view of the plot, using a function which control the angle and elevation of the initial view: ax.view_init(elevation, azimuth) and tried and works ax = Axes3D(fig) ax.view_init(64, -30) Question: Is it possible to include this function in the Axes3D documentation web page? or where I could find it in the webpage? http://matplotlib.sourceforge.net/mpl_toolkits/mplot3d/api.html?highlight=axes3d#module-mpl_toolkits.mplot3d.axes3d Thanks German On Fri, Oct 2, 2009 at 1:24 PM, German Ocampo geroca...@gmail.com wrote: Hello everybody How can I control the size of the Z axis in a 3D plot using Axes3D in matplotlib? regards german -- Come build with us!

Re: [Matplotlib-users] Axes3D - size of the Z axe
I was looking for something similar. It seems Axes3D() takes the angle as argument: import matplotlib.pyplot as plt import mpl_toolkits.mplot3d as m3d fig = plt.figure() ax = m3d.Axes3D(fig, elev = 20.0, azim = 45) in degrees. 2009/10/2 German Ocampo geroca...@gmail.com Hello After search in google, I found a solution changing the initial point of view of the plot, using a function which control the angle and elevation of the initial view: ax.view_init(elevation, azimuth) and tried and works ax = Axes3D(fig) ax.view_init(64, -30) Question: Is it possible to include this function in the Axes3D documentation web page? or where I could find it in the webpage? http://matplotlib.sourceforge.net/mpl_toolkits/mplot3d/api.html?highlight=axes3d#module-mpl_toolkits.mplot3d.axes3d Thanks German On Fri, Oct 2, 2009 at 1:24 PM, German Ocampo geroca...@gmail.com wrote: Hello everybody How can I control the size of the Z axis in a 3D plot using Axes3D in matplotlib? regards german -- Come build with us!

It looks like you are having tow problems -- first, you apparently
installed a new matplotlib over an old matplotlib and so there are
some old files laying around. Blow away site-packages/matplotlib and
reinstall. See
http://matplotlib.sourceforge.net/faq/installing_faq.html#cleanly-rebuild-and-reinstall-everything
Secondly, you need to be importing mplot3d from mpl_toolkits, it's new
location. You appear to be importing it from matplotlib.axes3d, it's
old location which is now deprecated. Eg see
http://matplotlib.sourceforge.net/mpl_toolkits/mplot3d/tutorial.html

Re: [Matplotlib-users] Axes3d
In theory, yes, but it's a completely untested theory. Each transform class has an input_dims and output_dims member that defines the input and output dimensions. So theoretically, you could create a perspective or orthogonal projection that maps from 3D to 2D.
