point3d label axes
Hi,
I am completely new to sage (like only a few hours) and I am trying to create a labeled plot of the results from a PCA analysis.
here is what I am doing in the sage command line:
from matplotlib.mlab import PCA
pca_info=PCA(data)
a=point3d(pca_info.Wt[:3,])
a.show()
The problem is, I need to add labels to the axes to try and understand what the plot is giving. After googling a bit, I found people referring to
axes_labels(['x','y','z'])
But I when trying the following, I get an attribute error
a.axes_labels(['PCA1 (%0.3f)' %pca_info.fracs[0],
'PCA2 (%0.3f)' %pca_info.fracs[1],
'PCA3 (%0.3f)' %pca_info.fracs[2]])
How does one generally add labels to a 3d plot, specifically to point3d()? Or has my googling failed me, and the answer is so obvious that I completely missed it.
Yeah, 3d plots and certain labels are not as far along as we'd like. It is possible (http://www.sagemath.org/doc/reference/sage/plot/plot3d/shapes2.html) to use text3d if you are lucky with positioning, perhaps?
Thanks for the info, it seems I have to use sage with something else, maybe something like mayavi.
