Hi John,
Allright, previously I was blocking the plotting event while trying to
update ticks instead of ticklabels. Hah trying to use 8103 ticks kills the
action :)
After looking at that example I brought parx = host.twiny() into the game.
Now when I do parx.xaxis.set_ticklabels(dccn.hms) I only get 5 wrong
ticklabels. If I do a simple plot(dccn.hms) ticklabels are properly set. I
know a few additional steps needed to make this work, but couldn't manage to
solve this yet.
On your suggested example try zooming into the plot, bottom and top x-axes
behave differently. JJ suggested to use xlim_changed and ylim_changed event
connection but how ? :)
One more question;
Say simply when I do: parx.xaxis.set_ticks(arange(10)), and later query:
I[30]: parx.xaxis.get_majorticklocs()
O[30]: array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
whereas
I[31]: parx.xaxis.get_majorticklabels()
O[31]: <a list of 10 Text major ticklabel objects>
I get objects here. Is there a way to see their actual values, besides the
object representation like in get_majorticklocs() method?
Thank you.
