Doesn't look like a feature to me :) The reason it is happening is that Tick is a complicated beast, and it always includes two Text objects, whether they are needed or not. Whether they are drawn is controlled by the attributes 'label1On' and 'label2On', not by the standard Artist.get_visible(). I don't see any reason offhand why it couldn't be modified to use get_visible().

[Matplotlib-users] Duplicate Ticks
Hello, I'm searching for a way to extract all text elements from a matplotlib figure including their positions, styles, alignments etc. I first tried to write a custom backend and to fetch all the texts from the "draw_text()" method of the renderer. In contrast to the documentation "draw_text()" does not receive a matplotlib.text.Text instance with all the necessary information but only a simple string and a pre-layouted position. So I found this "findobj" method to get all Text elements from a figure in a list, which is exactly what I was looking for. However, I get some weird duplicates for all the tick labels and I don't know how to handle them. This is a small example that uses findobj on the axis objects and prints the texts. import matplotlib import pylab as p p.plot([1,2,3]) p.xticks([1],["tick"]) ax = p.gca() fig = p.gcf() p.draw() def print_texts(artist): for t in artist.findobj(matplotlib.text.Text): if t.get_visible() and t.get_text(): print " %s @ %s" % (t.get_text(), t.get_position()) print "X-Axis" print_texts(ax.xaxis) print "Y-Axis" print_texts(ax.yaxis) On all my matplotlib installations, all tick labels have duplicates positioned at the end of the axis. Why? How to filter them out from a list of Text elements? Their get_visible() attribute is True. Another thing is that I first had to do a "draw()" call in order to have the ticks generated/updated at all. How do I force an update of the tick labels. Colorbar seems to have a "update_ticks()" method, but I can't find something similar for the axis ticks. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
