matplotlib-users Mailing List for matplotlib

I'm using matplotlib-3.10.0
I wanted to get exponent multiples of 3, and I want them formatted with
LaTeX notation like 3 x 10^6 (imagine I typed a superscript here), rather
than 3 M, which is what I'm getting. I tried:
 formatter = ticker.EngFormatter(useMathText=True,)
with and without also usetex=True, but I only get 3 M.
Any ideas?

Hey, folks!
I'm writing a blog series on how to make animations using
`matplotlib`. It will be a three part series. I have just published
the first part in the series on my blog.
Here is the link: http://whereistejas.me/
The first part covers the difference between the object-oriented and
pyplot interface. It serves as a mild introduction to the figure and
axes objects.
All comments and criticisms are welcome! Thank you!

​Sorry if this ultimately goes through more than once. I am having some
issues with submitting it....
I need to teach coordinate systems and transformations to a college
robotics class. I have used Tikz in the past to generate some graphics,
but I want to switch to doing everything in matplotlib if possible. (Tikz
is super powerful and makes beautiful graphics, but it always takes me a
long time to generate a figure).
One of my initial problems is drawing two axes on top of one another, but
with one of them rotated by an arbitrary angle. I am attaching the Tikz
result that I want to recreate in matplotlib. Other than drawing lines "by
hand", I don't really know where to start. Any help would be appreciated.
In case the mailing list doesn't allow attached graphics, here is a link to

Hello,
I am a beginner at Python (3.6) and using it for my PhD work. My question is about creating 3D wireframe plot to visualize a meshed sphere. 
I have 3 seperate 1D arrays which represent coordinates of nodes on the meshed surface. (X-coordinates, Y-coordinates and Z-coordinates) These arrays are obtained from a finite element model.
Using these coordinates I want to create a meshed surface of a sphere by using matplotlib. In most of the examples, X and Y coordinate arrays are being made 2D by "meshgrid" and a Z coordinate array is being created by calculation. However in my case I also have Z coordinates and cannot calculate it by using X and Y coordinates (which are recreated by meshgrid).
I would like to ask if there is a way to create a wireframe plot of a meshed surface by using three separate 1D arrays which represent coordinates of nodes.
Thanks for the consideration and your time.
Best regards,
Burak Ustundag

Hello,
I'm working to create a live plot by taking in data via a server and then plotting in a 3d scatterplot. I have a well thought out explanation (took a couple hours to produce) that I posted a few minutes ago on stack overflow.

I'm using the EngFormatter and Formatter from matplotlib 2.0.0, matplotlib.ticker . I have to go to a machine that uses an earlier 0.99. Is there an easy backward conversion to use those in 2.0 to 0.99?

Hi
I have been looking for an elegant/simple (working!) solution to create 
new complex markers for matplotlib.
For example, I would like to design a new marker which is the union of a 
set of vertices, for example (just an example), two petals which are 
symmetric (see verts1 and verts2) and two lines above and below (see 
verts3, and verts4). I would also like to have the petal possibly filled 
(or not) and the edgecolor of each vertices with possibly various 
colours (one petal is blue, the other is orange). How should I proceed?
A naive way forward is to do something like (for a double petal, the 
left one not being filled up, the right one being filled, see the 
definition for verts1, verts2, verts3, verts4 below):
## Code
x = rand(10)
y = rand(10)
verts = [verts1, verts2, verts3, verts4]
fc = ['k', 'None', 'None', 'None']
ec = ['b', 'orange', 'k', 'k']
for lverts, lfc, lec in list(zip(verts, fc, ec)) :
 scatter(x, y, marker= (lverts, 0), facecolor=lfc, edgecolor=lec, 
s=1000, label='My symbol')
==> HOWEVER, since these are done in a for loop, it is not considered as 
a single marker when I do, for example, :
legend(loc=0)
QUESTION: how should I manage this? (couldn't find the answer on the net)
Suggestion are most welcome!

Back When Gas Was 30¢ A Gallon
Peter S. Shenkin
Back when gas was 30¢ a gallon,
And love was only 60¢ away
Thus sang Tom T. Hall. I can’t say this story is exactly about that, but it took place exactly about then.
Mise en scène: Grant’s Tavern, Blairsville Precinct, Williamson County, (Southern) Illinois.
Ole Grant kept an overcoat hanging on a hook behind the door in all seasons. If there was trouble, he'd put it on. Everyone knew there was a revolver in the pocket. Or at least, everyone believed it, which was enough.
He had live country bands Friday and Saturday nights. He had a bowling machine, pinball, a few other games and a juke box. He had a bar, a roomy dance floor stocked with country honeys and live country music on the weekends, tables on an elevated platform at the back maybe 1/3 the size of the dance floor. The platform, that is.
One Saturday evening, 1969, I took a bunch of my hippie friends there. Including Alberto Navarro from Bogota and Mike Bartlett, a computer nerd who raced small cars. Both now deceased, which I am sorrier than you can imagine to have to say. Ron Manning and Peter Munch (grandnephew of the artist Edvard Munch) as well. Probably John Harty. We had spent the day imbibing various licit and illicit substances in the beautiful countryside and perhaps had had lunch at Ma Hale's in Grand Tower, unless that was another day, but either way we thought Blairsville would be good for a night cap. They put a few tables together in the back for us and the waitress got busy with other customers.
Alberto got annoyed at the lack of attention. He jumped up on a chair and shouted if they didn't come and serve us pronto he was going to put LSD in the Blairsville water supply. The rest of us were looking around nervously and trying to calm him down, hoping that Ole Grant wouldn't resort to the overcoat.
Just then the waitress came over and called Alberto "Dear" and asked what she could get him. That calmed him down considerably, which calmed the rest of us down considerably. There was no way they could have understood Alberto's accent anyway (which he never lost till his dying day, though his command of the English language was better than mine).
Either way, they seemed to be used to this sort of thing, which was fine by us.
Oh -- Tom T. Hall’s song is here <https://www.google.com/url?q=https://www.youtube.com/watch?v%3DgbPJ3Q9Tfbs&amp;sa=D&amp;usg=AFQjCNFQzJgaaMiV7bubM7SgWvIfwh3xsQ>. <https://www.google.com/url?q=https://www.youtube.com/watch?v%3DgbPJ3Q9Tfbs&amp;sa=D&amp;usg=AFQjCNFQzJgaaMiV7bubM7SgWvIfwh3xsQ>

Diego,
It isn't really clear from your description what the problem is. Is the
problem that the sub-vectors aren't all of equal lengths (i.e., a staggered
array)? Or is it that it is transposed from what you'd expect?

This would seem like a bug in that package's code. The traceback shows that it is performing its own check on the passed in kwargs, and failing to recognize it as a valid argument. I suggest contacting the maintainers of the "skill_metrics" package and find out from them if there is a bug in their package. I am unfamiliar with this package, so I can't say anything for certain.

This would seem like a bug in that package's code. The traceback shows that
it is performing its own check on the passed in kwargs, and failing to
recognize it as a valid argument. I suggest contacting the maintainers of
the "skill_metrics" package and find out from them if there is a bug in
their package. I am unfamiliar with this package, so I can't say anything
for certain.
Cheers!

Dear Experts.I have been trying to modify plot properties of taylor diagram from below package. I wanted to make markerfacecolor as None( this allows me to show symbols which falls over another) of s as possible in normal matplotlib plots but I am not sure how to pass the argument in modified figure environment of taylor plot. If I try to use markerfacecolor option the code says it do not know about such option. I was also checking it is possible specify alpha= n so that the color intensity of symbol can be modified. But both options are not working or I am not putting it in proper way in such situation. 
Please advice if it is possible.Sudheer

I am wondering if the "optimizations" you have are actually slowing you
down. I have never found myself needing to flush_events() or call update()
like that. Or to draw the artists like you are doing. Without seeing more
of the code, it is hard to judge. Have you tried using "runsnakerun" to
profile your code to find out what is actually slowing it down? I can get
60-70Hz without even trying for 3d plotting animations, and that is
probably more computation than this.

Thanks for the help (and sorry for the super-late reply).
I just tried blitting, but it doesn't really help. I cannot exceed 20 fps.
The problem is that I'm plotting data from a video file, so that for each
frame I need to draw a new array (not just a foreground). I think its just
to much data.
Thanks,
Hjalmar

Hi everyone,
Apologies for cross-posting : this event might be of interest to some of
the projects of the scientific Python community. We are trying to encourage
FOSS developers to focus on documentation for a week instead of fixing bugs
or implementing cool features!
Here are more informations about the project.
Thanks,
Nelle
Sign up your project for the docathon!
The Docathon is happening next week! We’ve already got several projects
signed up to participate in improving their documentation during the week.
We’ve put together a nifty project board
<https://bids.github.io/docathon/pages/projects/projects.html> so that we
can keep track of everybody’s progress during the week! If you sign up as a
project <https://goo.gl/forms/0cPpw01zehrEyDDE3>, we’ll post your
documentation commit stats like this:
How can I join in?
We want you to improve your documentation, wherever you are. To that
extent, we’ll keep track of project activity regardless of its location. If
you’d like to work with a group of people, here are a few specifics:
To kick off the docathon we’ll have a morning of tutorials on Monday, March
6th. These will cover particular tools and techniques for building great
documentation. If you’re at Berkeley then you can sign up here
<https://www.eventbrite.com/e/bids-docathon-kickoff-tickets-32302896834?aff=mcivte>.
This will also be live-streamed on Youtube, so you can watch from wherever
you are!
We’ll also have some working groups meeting periodically in cities around
the country. If you’d like to join in with these groups, click one of these
links:

You can also work remotely if you like, we will coordinate people via
email/GitHub, too.
Wherever you are, don’t forget to sign up as a participant
<https://goo.gl/forms/AaW2b24mMxOutxt02> so we can give some pointers on
how to contribute. Or, suggest a project
<https://goo.gl/forms/0cPpw01zehrEyDDE3> to work on and we’ll keep track of
its activity on our projects page
<https://bids.github.io/docathon/pages/projects/projects.html>.
Contact
If you have any questions, check out the Docathon website
<http://bids.github.io/docathon> or open an issue on our GitHub repo
<https://github.com/BIDS/docathon>.
Please feel free to forward this email to anyone who may be interested.
We'd love for other institutions/groups to get involved.

I usually install the matplotlib binaries from pipy and I don't
remember doing a separate installation of freetype.

Hi, Gents,
Many thanks for your thoughtful responses! Freetype is indeed available under a BSD-like licensse. But when I tried to install freetype on my Windows system using the binary provided from GnuWin32, it attempts to force me to accept the GPL3, which I cannot. Freetype's link to another binary supplied by GTK+ is broken. So, I guess I have two choices; compile freetype from the source, or download something like Anaconda, which I'd rather not do because I have Python already installed.
If you have any other ideas, I'd be happy to hear them.
Best,Chad

Well, if Freetype were only distributed under the GPL, you couldn't distribute matplotlib in binary form without providing the source code.
However, Freetype is distributed under more than one license. (see: https://www.freetype.org/license.html )
Because it's distributed under a BSD-style license in addition to the GPL, it can be distributed in binary form, subject to an accreditation clause: http://git.savannah.gnu.org/cgit/freetype/freetype2.git/tree/docs/FTL.TXT
In the past, I have gotten approval from corporate lawyers at a very large company to use freetype (and matplotlib) in an application that was being distributed in binary form. The dual-licensing of freetype was key in that particular case.
Or that's my take on it, anyway. I'm not a Lawyer, so don't consider this legal advice in any way.
Cheers!
-Joe

I just went to install matplotlib version 2.0.0, and it has a dependency called "freetype". This software appears to be licensed under GPL3. My reading of that latter license is that, if someone wanted to distribute a compiled version of a program requiring matplotlib, that entire program would fall under the GPL3 license. I'm sure that would be a non-starter for many, many projects.
Does anyone have any takes on this?
