Subject: [Matplotlib-users] 3D scatter plot with 'unlimited' Z axis
Message-ID: <1e7ccace-61a6-cbac-88c8-9d571f305f9b@willfurnell.com>

Hey everyone,

I'm looking into a 3D scatter plot - basically converting a NumPy array
to a 3D plot, where X and Y correspond to the X and Y co-ordinates on
the graph and the Z values corresponds to a particular height on the graph.

This is how I'm generating the lists:


x = list(range(0, 256))
y = list(range(0, 256))
z = []

for i in range(0, 255):
    for j in range(0, 255):
        z.append(ll[i][j])

where ll is my 2D array...

I've seen the scatter function with 3d projection, but this requires the
Z array length to be the same length as the X and Y lengths, whereas
I'll need to be plotting X*Y points (256*256). Is there some way that I
could achieve this?

Thanks,

Will.

```
x = np.arange(256)
y = np.arange(256)
xx, yy = np.meshgrid(x, y)
```
Then your `xx` and `yy` will be 2D, just like your `ll` variable. Then, you
pass the flattened versions of those three variables (i.e., `xx.flatten()`
or `xx.flat`) to the 3d scatter call.

I hope that helps!

Diego,

It is hard to say much without also seeing your csv file.

What is the difference between the type and contents of the `collabel` in
both cases?

It looks like the later returns a tuple instead of a list (see
https://docs.scipy.org/doc/numpy-1.15.0/user/basics.rec.html#manipulating-and-displaying-structured-datatypes
).

My code was running correctly, but now with the following ERROR message:

*Cannot mix incompatible Qt library (version 0x50b01) with this library
(version 0x50b02)*
*Aborted (core dumped)*

I actually just want to use *matplotlib* as:

import matplotlib.pyplot as plt
import matplotlib.dates as md


Now, whenever I want to use matplotlib, I got the above error...


Can anybody help?

Cheers

Did you just recently upgraded to matplotlib v3.0? I am guessing somehow
that upgrade also did some things to your QT libraries as well. You can try
changing your default backend to something like TkAgg so that it doesn't
try the QT based backends.

Can you do

import PyQt

without error?  I suspect this is due to installation issues between Qt and
PyQt versions.

I upgraded from Qt5.11.1 to Qt5.11.2, and reinstalled PyQt5 ...

Thank you everyone...

Hello, I try to do wulff plot for pole figures in crystallography [1].

I found a project which seems to do the job[2], but it is quite old and not working with the latest numpy vesion.

now my question, is is it possible to do this kind of plot (the equal angle[2]), with just matploltlib or basemap ?

thanks for your help

I would probably try seeing what can be done to fix this package. Most
likely it is just doing some deprecated thing that needs to be rewritten in
a couple places.

I definitely wouldn't try to do it in basemap (or cartopy for that matter)
because they are so geared towards cartography.

For what it's worth, the examples on the git repo work on my mac with mplstereonet 0.5 from pypi and with version 0.6-dev installed from the git repo.  They work under python 3.6.6 and 3.7.0 with matplotlib 3.0.0 and numpy 1.15.2

I took the version from pypi.
I was affected by a bug when using the weight keywork of the contour plot.
At  some point it compared a numpy array to False, whcih doesnot work anymore.

I was asking because it seems to me that  the upstream is not active anymore. this is why I was asking if this could be done with a librry  which is already available in Debian.

Ah, well, have you tried submitting a bug report to the project?
Oftentimes, small packages like mplstereonet don't get a lot of activity
because they are relatively small and simple and tend to work just fine for
most cases. If you provide a traceback, it should be fairly obvious how to
fix the bug.

For what it's worth, I'm the author of mplstereonet, and I'd be happy to
address your problem.

The only numpy depreciations that I'm aware of affecting the project don't
actually change any behavior, they just issue warnings that the old
behavior was ambiguous.

One note: the weights agruments to density contorting are relatively
untested and not frequently used. You're likely hitting a corner case that
I'm not aware of, but I can confirm that they work for the cases I've
tested.

If you could add a bit more detail and the traceback you're seeing, I'd
love to fix your issue.

Thanks!
-Joe

Hello, thanks a lot, I will do a MR, next week if I have time :).
I would like also to upload it into Debian.
Is it ok for you ?

Subject: [Matplotlib-users] matplotlib 3.0 animation blitting bug?
Message-ID: <1539693671819-0.post@n5.nabble.com>

This looks like a bug to me, but maybe someone knows better...

After updating to matplotlib 3.0, I get the following problem on animations
that use blitting: A horizontal bar appears at the bottom and a vertical bar
on the right of function animation plots.  The attached screenshot shows the
problem for the "The Bayes update? example from the matplotlib animation
examples:
https://matplotlib.org/gallery/animation/bayes_update.html#sphx-glr-gallery-animation-bayes-update-py.

This same problem occurs on all animation files I?ve tried that use
blitting.  None of them had the problem before I updated.

Interestingly enough, when I save the animation to an mpeg4 file, there is
no problem in the saved movie file.

This occurs on a system configured as follows:

macOS: 10.13.6
Python: 3.7.0 Anaconda distribution
matplotlib: 3.0.0

I should have stated that I'm using the Qt5Agg backend, which seems to be
where the problem lies. The animation works without a problem for the TkAgg
backend.

Message-ID: <CAA48SF8OvQ1DqC+wCrx8C1i471mEpeMbeh1qndD6rtBO2KWz_g@mail.gmail.com>

Folks,

The current proposed release schedule for Matplotlib is:

Nov 3-4, 2018
 - Matplotlib 2.2.4 LTS
 - Matplotlib 3.0.1

These are both bug-fix releases.  Futher bug-fix releases will be as-needed.

April 2019
 - Matplotlib 3.1

This will be a feature release and per our dependency policy [1], we plan
do drop support for python 3.5 which was initially released in September
2015 [2].

Message-ID: <1539974373405-0.post@n5.nabble.com>

Hi,
Have a problem that is driving me nuts, and have narrowed it down to pyplot,
and anything depending on pyplot.

This command works fine:
import matplotlib as mpl

But when I run
import matplotlib.pyplot as plt

The python icon in docks starts jumping up and down and I get:
[Error] Failed to load resource: the server responded with a status of 404
(Not Found) (preact.min.js.map, line 0)
[Error] Failed to load resource: the server responded with a status of 404
(Not Found) (preact-compat.min.js.map, line 0)
[Error] Failed to load resource: the server responded with a status of 404
(Not Found) (index.js.map, line 0)

Running Python 3.7, Matplotlib 3.0 on a Mac OS High Sierra, and all worked
fine up till just recently

Any ideas anyone?

It looks like you might have things configured to default to a different
backend than normal.  Are you running things inside of a notebook?  It
looks like it's trying to run one of the web-based backends by default, and
that backend can't set things up correctly.

What happens if you do:

python -c "import matplotlib; matplotlib.use('tkagg'); import
matplotlib.pyplot as plt"

Or equivalently, try doing:

import matplotlib
matplotlib.use('tkagg')
import matplotlib.pyplot as plt

fig, ax = plt.subplots()
ax.plot(range(10))
plt.show()

If these type of examples work, have a look at which backend you have
things set up to use:
https://matplotlib.org/faq/usage_faq.html#what-is-a-backend.

Hope that helps,
-Joe

Thanks Joe!

Changing the backend from ?macosx" to ?tkagg? had no real impact - just that little rocket now bouncing closer to the center of the dock.
The only recent, i.e. potentially relevant update I have made is updating to Matplotlib to 3.0

It seems like the ?missing? json-fies, generating a 404 GET when I run Jupyter, are related to scripting

Thanks,
Ulf

David,

Is this on a retnia display?  If you re-size while the animation is running
does it fix it's self?

When saving to disk we re-render each frame 'from scratch' so I am not
surprised that it does not show up there.

Subject: [Matplotlib-users] matplotlib 3.0 animation blitting bug?

That does help to localize the bug as Qt has support for high-dpi (to
support full resolution figures we have to first ask the desktop to not
give us effectively half-resolution and then internally double the rendered
resolution) where as tk does not.  It looks like something is getting
confused about what parts of the buffer need to be updated / restored /
cleared during blitting.

There are some bugfixes in master and slated for v3.0.1 (soon-ish) that may
be relevant for your situation. Could you try installing from the master
branch?

Subject: [Matplotlib-users] 3.0 upgrade
Message-ID: <1540305579964-0.post@n5.nabble.com>

Hi,

I was using Matplotlib ver 2.2.2 on windows 10 using anaconda distribution.
Now I have upgraded anaconda distribution with Matplotlib ver 3.0.0. Facing
few issues with the code that was working fine with 2.2.2.

1. In 3D plots using mplot3d, for multiple subplots,
plt.tight_layout(w_pad=5) worked fine with 2.2.2, but same code is giving
the following error
<http://matplotlib.1069221.n5.nabble.com/file/t5188/tight_layout_err.png> , 

and output display is one long vertical line with some jumbled letters.
When I remove titght_layout() statement, I get adequate space in between the
plots, but legend overalps with title. How can I fix this overlap issue? 

2. For all 3D plots figure size gets too small, compared to the size I used
to get with 2.2.2 version. It is the same for single plot or multiple
subplots in the figure. Even figsize=(15,10) produces very small figure as
attached here
<http://matplotlib.1069221.n5.nabble.com/file/t5188/3Dfigure_Sizeissue.png> 

whereas 2.2.2 produced full screen figure as shown below.
<http://matplotlib.1069221.n5.nabble.com/file/t5188/sizewith222.png> 

Appreciate any help in resolving these two issues.

This will be better in 3.0.x: https://github.com/matplotlib/matplotlib/pull/12241 <https://github.com/matplotlib/matplotlib/pull/12241>

Take the legend out of the layout: `leg = plt.legend(); leg.set_in_layout(False)` may help, but for 3-d plots there is still the spine issue.  Sorry for the bother.

These look like dpi issues.  Not sure what is causing that.  How are you producing the pngs?

Cheers,   Jody

Thanks a lot, Judy for quick response.

1. Tried your solution 'leg = plt.legend(); leg.set_in_layout(False)`,
unfortunately that has not helped

2. I am running the code in Jupyter Notebook, in the output cell I see
figure size much smaller with 3.0.0 compared to 2.2.2. For this post, I
saved these output figures from both 3.0.0 and 2.2.2 using mouse right click
and save, which by default saves in png format. Hope this helps

OK, this is all likely https://github.com/matplotlib/matplotlib/pull/12241 <https://github.com/matplotlib/matplotlib/pull/12241>  Either download and install from master or revert to 2.2.3 until 3.0.1 is out

Thanks, Jody

I am not customizing spines or any other figure/axes/axis attributes. I am
plotting 3D data, for various combination of elevation and rotation
parameters, and adding title and legend for each of the axes(each
combination of elevation and rotation). Idea is to view the data from
different directions.

Regarding the figure size issue also, I am not specifying and dpi parameter,
but using default setup.

Encountered few issues with axes_grid1 toolkit functionality also with
version 3.0.0 compared to 2.2.2. Posted them in developer group. 

I just want to make sure that I am not making any mistake at my end, and if
they are real issues with version 3.0.0, let development team know about
them so that they can fix them at some point.

Thanks once again for your attention and prompt response.

Regards
PSR

This has all been fixed in https://github.com/matplotlib/matplotlib/pull/12241 <https://github.com/matplotlib/matplotlib/pull/12241>.  It was definitely a bug in 3.0.0, and will be fixed in 3.0.1 when it is released.

Thanks,  Jody

I am sorry, I am unable to relate my problems with the issue mentioned in

Have you got a chance to look at my other post in developer group?

I am sorry, earlier I clicked thru 12241 thread, which was not clear. This
12239 thread is clear to me now.

Any thoughts on other issues that I posted to developer forum(should I also
post them on user forum as well?) and figure size issue in 3D plots?

Thanks
PSR

Subject: [Matplotlib-users] Range Slider?
Message-ID: <e8a158a0-33ee-7ca2-bf56-2866fd9b448c@werthmuller.org>

Hi matplotlib users,

Matplotlib has the Slider-widget (matplotlib.widgets.Slider).

Is there a way to achieve a range-slider, hence to have a slider where 
you can drag from both sides and therefore get two values, the minimum 
and the maximum. For instance as it is implemented in the Jupyter 
widgets, see 
https://ipywidgets.readthedocs.io/en/stable/examples/Widget%20List.html#IntRangeSlider

Thanks,
Dieter

Folks,

This is the first bug fix release for the 3.0 series which fixes
several

 - Fix failure to import bug when on Python 3.6.7 and 3.7.1
 - Fixed a number of failure to import bugs around finding fonts
 - Fix Qt4 backend
 - Fix bug on OSX that recursively searched current directory for fonts
 - Fix bouncing-rocket on OSX when doing backend fallback and not
   selecting OSX
 - Temporarily restore several private APIs to unbreak cartopy
 - Make pyplot more tolerant of varying signatures in 3rd-party
   sub-classe
 - Improve datetime64 unit handling
 - Fixed several poor interactions with tight_layout

The wheels are up on pypi and updated packages are available on main
anaconda / conda-forge.  A big thank you to the prompt work of the
packagers!

The documentation will catch up with the release in the next few days.

Tom

Thanks for that Jody, I did just "get lucky".

Some assessment of this shows the high CPU associated with this operation
is at least partially avoidable.

The majority of the CPU time, according to:
  python3 -m cProfile -s time plotit.py -s|head -n20
is in or under StrCategoryFormatter._text which seems to be getting called
exponentially more times than I would expect. Of the order number of
categories squared in my samples, with 40K calls for 100 categories and 4M
for 1000 on mpl 2.2 amd 6M on mpl 3.0. Seems high.

Within the _text function in 2.2, the most expensive operation is the
constant test of the numpy version. This can be significantly reduced by
moving the constant expression with a simple change like:

diff --git a/lib/matplotlib/category.py b/lib/matplotlib/category.py

Perhaps not surprising that hasn?t been optimized, because most folks don?t have that many categories.  If you have an actual use-case for that many categories, submitting a bug report on Github would be great.  

Cheers,   Jody

This is an intentional change to support categorical string-data (see
https://matplotlib.org/gallery/lines_bars_and_markers/categorical_variables.html)
in 2.1.

Plotting a list of strings that happened to be floats worked <2.1 by chance
because there was a `np.asarray(data)` someplace which worked because numpy
implicitly did the conversion.   You are not the only person to hit this,
we miss-estimated how used this accidental feature was, sorry.

The most reliable path is to convert your data to numeric types before
handing it to Matplotlib (this will be guaranteed to work on all past and
future versions of Matplotlib!).

Does not appear to be one, but a PR would be welcome to add one!

I am not sure if that will actually be easy to add though (as the
single-ended slider does not have a notion of 'end' yet or a thumb).   The
way we achieve this functionality in the subplot tool is to have two
sliders (one for the top and one for the bottom) with linked callbacks.

I don't see a difference in the figure size.

Could you post a minimal example that generates the issue you are seeing?
That makes it much easier for us to help debug the issue!

Subject: [Matplotlib-users] Arranging subplots on a square regular grid
Message-ID: <faf29629-2599-f10c-6b08-38a46f78b40d@grinta.net>

Hello,

I would like to arrange a number of square subplots (as in subplots with
square axes as obtained with `ax.axis('equal')`) in a grid such that the
distance between rows and columns is exactly the same.

I can use a GridSpec but, as soon as I ask for the axes to be square,
the distance between axes changes. Is there a way to enforce the equal
distances constrain (namely stretch the padding between the axes and the
margin of the figure but do not stretch the padding between axes) or the
only solution is to do it manually?

Thank you in advance.

Best,
Dan

If you're okay with a fixed figure size, you can use plt.figaspect to set
this up fairly easily: (i.e. this will be incorrect as soon as you resize
the plot window)

import numpy as npimport matplotlib.pyplot as plt

nrows, ncols = 8, 12
dx, dy = 1, 2
figsize = plt.figaspect(float(dy * nrows) / float(dx * ncols))

fig, axes = plt.subplots(nrows, ncols, figsize=figsize)for ax in axes.flat:
    data = np.random.random((10*dy, 10*dx))
    ax.imshow(data, interpolation='none', cmap='gray')
    ax.set(xticks=[], yticks=[])

pad = 0.05 # Padding around the edge of the figure
xpad, ypad = dx * pad, dy * pad
fig.subplots_adjust(left=xpad, right=1-xpad, top=1-ypad, bottom=ypad)

plt.show()

(From here, for reference:
https://stackoverflow.com/questions/32633322/changing-aspect-ratio-of-subplots-in-matplotlib/32635933#32635933
)

If you need the spacing to remain constant as the figure size changes,
it's possible, but more complex.  You may find it's easiest to use
draw callbacks in that case.

Hope that helps,

-Joe

Hi Daniele,

This is also explicitly the use-case that `axes_grid1` toolkit is meant for.   I?m trying to move as much axes_grid1 stuff out of the toolkit into the main code as possible, but what you want is orthogonal to how layout managers that are currently in matplotlib work, so axes_grid1 is still useful here.

Cheers,  Jody

Hi Jody,

thank you very much. That's exactly what I was looking for!  I don't
know how I missed it in the documentation.  It would be very nice if
this could expose an API similar to the GridSpec one, but I don't know
how feasible this is.

Thanks,
Dan
