zoomed in detail box

Community matplotlib-users

Hi everyone!

I’m also trying to do a detailed zoomed area of my plot, but I can’t manage to put the box in the position I want, bbox_to_anchor didn’t work in my case:

axins = zoomed_inset_axes(ax,3,loc=2,bbox_to_anchor=(0,0,0.5,0.5),bbox_transform=ax.transAxes)

This bbox_to_anchor tuple is just an example. I only want to move the zoomed box a little to the right, since the ticklabels overlap.

Any idea?

I really appreciate your help!

Wow - this is really amazing. Sometimes it can be a bit frustrating

when I’m working to a deadline to figure out the details of Bbox’s and

such but when I find something like this it really makes it worth

while! It does exactly what I want, really easy to use and only took

about 5 lines! (It would be nice if there were some docstrings in

there though :))

I’m afraid I didn’t really understand how to apply this in my case…

I guess I would have to set the position and everything by hand

instead of using the zoom helper. I preferred to use the zoom helper,

but found the legend loc settings put it slightly too close to the

edge of the surrounding axes for my taste.

So after checking the docstrings for how to position legends I came up

with something that works, but it required a minor change to the

inset_locator.py to pass the bbox_to_anchor and bbox_transform (it

looks like this was intended since they have None default values):

robin-mbp-3:~ robince$ diff

/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/mpl_toolkits/axes_grid/inset_locator.py

code/scipy_build/matplotlib/lib/mpl_toolkits/axes_grid/inset_locator.py

< axes_locator = AnchoredZoomLocator(parent_axes, zoom=zoom,

loc=loc, bbox_to_anchor=bbox_to_anchor,bbox_transform=bbox_transform)

axes_locator = AnchoredZoomLocator(parent_axes, zoom=zoom, loc=loc)

With this minor change I get exactly what I want!

Thanks for the catch. I’ll commit the change to the svn soon.

By the way, borderpad keyword is meant to do what you want. However, I

just found that it does not work sine the option is not properly

handled. I’ll fix this in the next commit.

ax1ins = zoomed_inset_axes(ax1, 3,

bbox_to_anchor=(0.1,0,1,1),bbox_transform=ax1.transAxes, loc=6)

plot_trial_dists(res515[0],8,ax=ax1ins)

ax1ins.set_xlim([5, 50])

ax1ins.set_ylim([0, 0.04])

ax1ins.set_xticks()

ax1ins.set_yticks()

mark_inset(ax1, ax1ins, loc1=2, loc2=4, fc=“none”, ec=“0.5”)

thanks again, this is really terrific!

Thank you for your help, but I have already read this link.

I am using zoomed_inset_axes, but the default position overlaps the yticks and the parent axe ticks, so I am trying:
axins = zoomed_inset_axes(ax, 3,bbox_to_anchor(0.5,1),bbox_transform=ax.figure.transFigure, loc=2)

but it doesn’t work.
I have also tried:
box = axins.get_position()
axins.set_position([box.x0+0.5, box.y0,box.width, box.height])

and the position is changed (doing a print I check the differences), but not in the plot.

I guess I am doing something wrong, but I can’t tell.

Any help would be really useful.

Cheers!

This is supposed to work, and my quick test did work. Can you post a

Thank you for your help.

A simple example that doesn’t work for me is:

···

import pylab as p
import numpy as np
from mpl_toolkits.axes_grid.inset_locator import zoomed_inset_axes
from mpl_toolkits.axes_grid.inset_locator import mark_inset
from mpl_toolkits.axes_grid.anchored_artists import AnchoredSizeBar
from matplotlib.ticker import MaxNLocator

fig = p.figure(figsize=(12,8))
ax = p.subplot(111)

z = p.arange(0,1.415,0.01)
d = z**2+np.random.random(len(z))

ax.plot(z,d,‘ro’,label=‘text’)

p.xlabel(‘z’,fontsize=18)
p.ylabel(‘Luminosity distance’,fontsize=18)
p.grid(True)

axins = zoomed_inset_axes(ax, 3,bbox_to_anchor=(0.5,0.5),bbox_transform=ax.figure.transFigure, loc=2)

axins.plot(z,d,‘r.’)

ax.legend(loc=2,bbox_to_anchor=(1,1))

x,y = (0.86,1.3)
x2,y2 = (1,1.7)
axins.set_xlim(x,x2)
axins.set_ylim(y,y2)
axins.tick_params(axis=‘both’,labelsize=12)
axins.xaxis.set_major_locator(MaxNLocator(2))
axins.yaxis.set_major_locator(MaxNLocator(3))

mark_inset(ax,axins,loc1=1,loc2=3, fc=“none”, ec=“0.5”)

p.draw()
p.show()

The “bbox_to_anchor” label is supposed to move the zoomed axis, but it does nothing, no matter what two numbers I place there.
I guess that I miss something, but I can’t figure out what. I really appreciate your help.

Best regards,
Illa

Your code works as expected in my side.
So, changing (0.5, 0.5) to something like (0.6, 0.5) has no effect in
your side?
Hmm, what is you matplotlib version? Maybe this is a bug in old
version of matplotlib.

I wasn't quite sure what to expect, but based on Jae-Joon's note:

So, changing (0.5, 0.5) to something like (0.6, 0.5) has no effect in

It seems to work on my installation. I actually changed to (0.3,0.5) which made a nice view.

Hmm, what is you matplotlib version?

Exactly, changing (0.5, 0.5) to something like (0.6, 0.5) has no effect in my side.

My python version is: 2.7.2
and matplotlib: 1.1.0

So maybe is a version problem, but it’s the work computer so I can’t update easily anything. I will try other computer.

Thank you all for your help,
Illa
