ToolManager
by Juan Nunez-Iglesias April 28, 2018

April 28, 2018

Hi, I’m trying to add elements to the matplotlib toolbar *using the Qt5 backend*. I tried running this example code: https://matplotlib.org/examples/user_interfaces/toolmanager.html But unfortunately it fails when using Qt5 with the error fig.canvas.manager.toolmanager.add_tool('List', ListTools) AttributeError: 'FigureManagerQT' object has no attribute ‘toolmanager' Is toolmanager only available for GTK? Is there an equivalent way of achieving what the script is doing in other backends? Thanks, Juan.

I am running up to date Matplotlib in Python3.5 on my Debian Stretch Platform. I have not made any changes of which I am aware, but I have started getting errors when running a Python script that I have written to plot data obtained from a FORTRAN program. Enter Molecule ID: A Traceback (most recent call last): File "MolT_5IMT_w_3_2_plot.py", line 83, in <module> fig.savefig(name_plt,bbox_inches='tight') File "/usr/local/lib/python3.5/dist-packages/matplotlib/figure.py", line 1814, in savefig self.canvas.print_figure(fname, **kwargs) File "/usr/local/lib/python3.5/dist-packages/matplotlib/backend_bases.py", line 2180, in print_figure self.figure.dpi = dpi File "/usr/local/lib/python3.5/dist-packages/matplotlib/figure.py", line 436, in _set_dpi self.set_size_inches(w, h, forward=forward) File "/usr/local/lib/python3.5/dist-packages/matplotlib/figure.py", line 745, in set_size_inches manager.resize(int(canvasw), int(canvash)) File "/usr/local/lib/python3.5/dist-packages/matplotlib/backends/backend_tkagg.py", line 540, in resize self.canvas._tkcanvas.master.geometry("%dx%d" % (width, height)) File "/usr/lib/python3.5/tkinter/__init__.py", line 1698, in wm_geometry return self.tk.call('wm', 'geometry', self._w, newGeometry) _tkinter.TclError: can't invoke "wm" command: application has been destroyed ------------------ (program exited with code: 1) Press return to continue I have attached the Python script and an input file to this message. I would appreciate some assistance in solving this problem Thanks in advance. -- Stephen P.

autoscale y axis in different [x1,x2] range
by jlx Dec. 2, 2017

Dec. 2, 2017

hey everyone, I meet a problem about autoscale. I change the x axis range so that I can see the details of the curve, but y axis range is always the same, it does not change automatically to zoom in. I tried autoscale on and set_autoscale_view, but do not work, could you help me about that? the following are curves at whole x range and [x1,x2] range: <http://matplotlib.1069221.n5.nabble.com/file/t5114/whole.png> <http://matplotlib.1069221.n5.nabble.com/file/t5114/10-20.png> So how to make the black, red and blue curves fit the subplot window automatically? Thank you! -- Sent from: http://matplotlib.1069221.n5.nabble.com/matplotlib-users-f3.html

size of the picture
by vincent_mathoscope Dec. 2, 2017

Dec. 2, 2017

hi for the book iwrite i need fonts in size 10 i put this size to the fonts and the exported picture, when included in my TeXmacs document without changing the size, present fonts that fits approximatively to this size of 10 but my pictures are really to big ; if i reduce them (they are png) then of course the fonts are reduced also i have been searching on internet since 2 days, looking for the right instruction to fix the size of the picture i did not find my answer here : https://stackoverflow.com/questions/8775622/exact-figure-size-in-matplotlib… <https://stackoverflow.com/questions/8775622/exact-figure-size-in-matplotlib…> here the topic seemed to be mine : http://scipy-cookbook.readthedocs.io/items/Matplotlib_AdjustingImageSize.ht… <http://scipy-cookbook.readthedocs.io/items/Matplotlib_AdjustingImageSize.ht…> but this code, just copy-pasted from this link : gave this message : AttributeError: 'Figure' object has no attribute 'set_figsize_inches' of course i can fix the font to some random value say 24 and reduce the picture to a random % and, by trials and approximations, find the right size and the right % so that the text in my pictures seem to be 10 i'm sure it must exist a more satisfying way but can not find it i am just missing this point to start working thanks if you have ideas. ----- –––––––––––––––––––––––––– Vincent Douce :=: Mathoscope :=: http://mathoscope.xyz 06°13°11°07°26 Bagnères de Bigorre 65200 -- Sent from: http://matplotlib.1069221.n5.nabble.com/matplotlib-users-f3.html

No, not inappropriate per se, but given your motivation, you may want to post (and subscribe) to matplotlib-devel instead/also. Also, if you "dig around" at the main site--matplotlib.org--I think you'll be able to find a history of the package (if not, pretty sure Wikipedia has one), and definitely contributor guidance (e.g., https://matplotlib.org/devel/gitwash/development_workflow.html?highlight=hi… and https://matplotlib.org/devel/gitwash/maintainer_workflow.html?highlight=his…, both of which I found by entering "history" into the home page search box; however, both of those results are "advanced," so dig around more for "how to get started" and "style and documentation guidlines"). Happy hunting, and thanks for being interested in contributing! DLG On Wed, Nov 29, 2017 at 1:28 PM, Rushikesh Padia <padiarushi3012(a)gmail.com> wrote: > Actually I am a beginner and inexperienced.

ValueError: Can only output finite numbers in PDF
by Neal Becker Nov. 26, 2017

Nov. 26, 2017

I can plot my semilogy plot fine to Qt5Agg backend, but switching to pdf gave the error ValueError: Can only output finite numbers in PDF Of course I can workaround it, but it's inconsistent (and annoying).
