This will give you additional information about which backends Matplotlib isloading, version information, and more. At this point you might want to makesure you understand Matplotlib's configurationprocess, governed by the matplotlibrc configuration file which containsinstructions within and the concept of the Matplotlib backend.
While attempting to use matplotlib.pyplot with the latest version of matplotlib (updated through the Anaconda distribution) I got a very similar error. The error appears to be between the root python version and the Anaconda distribution as the following solves the problem:
I tried installing the most recent version of QGIS, and the install fails because it can't find matplotlib. I'm thinking this is because I didn't use easy_install, which appears to put packages instead under /Library/...
I ran into the same problem. My matplotlib is installed under /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python. In case anyone is interested, I was able to solve this problem by running this command:
It is due to the fact that the installer that is hardcoded to look for matplotlib under /Library/Python/2.7/site-packages/matplotlib-override. Further the installer does not provide user to specify path of matplotlib at time of installation.
I am using Affinity Designer (last version) on Windows 10 for my work. I have generated a pdf with matplotlib on python. The pdf looks ok (see attached) but the labels do not display properly when opening the file with Affinity Designer (see the screenshot). However, the pdf displays correctly in Illustrator.
Hello everyone, I face the same issue using different pdf's, but also with svg files saved with seaborn / matplotlib. In all pdf readers they're read correctly, but especiialy the text is formatted wrong:
Affinity apps have an issue with how matplotlib writes (codes) the text in both the PDF and the SVG formats. Some other applications, including PDF editors, are able to interpret this as text. But some other applications also have an issue with it (open the SVG in Inkscape and look at the "text").
Open the SVG in a text editor and try to find the "text" (the actual text, not the comments).
There is another discussion around here somewhere about the text coding in these files.
I hope the developers understand that this is not just an annoying bug. These bugs make it literally impossible to use Designer efficiently for graphics in the scientific community in general. If I create several graphics and at least one of them includes a file from matplotlib I won't use a different tool just for this one graphic. I switch the tool for all graphics of this project. And since this is the case for almost 99% of my projects Designer is not useful for me at all at this point.
Thanks for all of the suggestions. I decided not to show the chart through the matplotlib module. Since the features within that window were limited I saved it out as an image, and opened it in the default picture viewer. This allowed the process to complete without being held up by the chart window.
A while ago I uploaded a document Using Python and matplotlib to create profile graphs and recently there was a question about how to create a PDF with multiple graphs on a single page. In this case I am taking it a little step further and will create a multi page PDF file that will contain 6 graphs on each page base on a combination of suggestions made at this page: matplotlib - Python saving multiple figures into one PDF file - Stack Overflow .
I am working on a project (a Dataquest guided project) and a heatmap that I am creating does not show properly. After some searching on the internet I figured out that to solve that I should update matplotlib from version 3.1.1 to version 3.1.2.
The python visualization world can be a frustrating place for a new user. Thereare many different options and choosing the right one is a challenge.For example, even after 2 years, this article is one of the top posts thatlead people to this site. In that article, I threw some shade at matplotliband dismissed it during the analysis. However, after using tools such as pandas,scikit-learn, seaborn and the rest of the data science stack in python - Ithink I was a little premature in dismissing matplotlib. To be honest, Idid not quite understand it and how to use it effectively in my workflow.
Now that I have taken the time to learn some of these tools and how to use them withmatplotlib, I have started to see matplotlib as an indispensable tool.This post will show how I use matplotlib and provide some recommendations for users gettingstarted or users who have not taken the time to learn matplotlib. I do firmly believematplotlib is an essential part of the python data science stack and hope thisarticle will help people understand how to use it for their own visualizations.
The reason two interfaces cause confusion is that in the world of stack overflowand tons of information available via google searches, new users will stumbleacross multiple solutions to problems that look somewhat similar but are not the same.I can speak from experience. Looking back on some of my old code, I can tell that thereis a mishmash of matplotlib code - which is confusing to me (even if I wrote it).
Another historic challenge with matplotlib is that some of the default stylechoices were rather unattractive. In a world where R could generate some reallycool plots with ggplot, the matplotlib options tended to look a bit ugly incomparison. The good news is that matplotlib 2.0 has much nicer styling capabilitiesand ability to theme your visualizations with minimal effort.
Despite some of these issues, I have come to appreciate matplotlib because itis extremely powerful. The library allows you to create almost any visualizationyou could imagine. Additionally, there is a rich ecosystem of python toolsbuilt around it and many of the more advanced visualization tools use matplotlib asthe base library. If you do any work in the python data science stack, you willneed to develop some basic familiarity with how to use matplotlib. That isthe focus of the rest of this post - developing a basic approach for effectivelyusing matplotlib.
The other benefit of this knowledge is that you have a starting point when yousee things on the web. If you take the time to understand this point, the restof the matplotlib API will start to make sense. Also, many of the advanced pythonpackages like seaborn and ggplot rely on matplotlib so understanding the basicswill make those more powerful frameworks much easier to learn.
The rest of this post will be a primer on how to do the basic visualizationcreation in pandas and customize the most common items using matplotlib. Onceyou understand the basic process, further customizations are relatively straightforward.
Up until now, I have been relying on the jupyter notebook to display the figuresby virtue of the %matplotlib inline directive. However, there are goingto be plenty of times where you have the need to save a figure in a specific formatand integrate it with some other presentation.
Hopefully this process has helped you understand how to more effectively usematplotlib in your daily data analysis. If you get in the habit of using this approachwhen doing your analysis, you should be able to quickly find out how to do whatever youneed to do to customize your plot.
matplotlib is a python 2D plotting library which produces publicationquality figures in a variety of hardcopy formats and interactiveenvironments across platforms. matplotlib can be used in Python scripts,the Python and IPython shell (ala MATLAB or Mathematica), webapplication servers, and six graphical user interface toolkits.
The pyplot API has a convenient MATLAB-style stateful interface. In fact, the matplotlib Python library was originally written as an open source alternative for MATLAB. The OO API and its interface is more customizable and powerful than pyplot, but considered more difficult to use. As a result, the pyplot interface is more commonly used, and is referred to by default in this article.
Matplotlib is also available as uncompiled source files from GitHub. Compiling from source will require your local system to have the appropriate compiler for your OS, all dependencies, setup scripts, configuration files, and patches available. This can result in a fairly complex installation. Alternatively, consider using the ActiveState Platform to automatically build matplotlib from source and package it for your OS.
Numpy is a package for scientific computing. Numpy is a required dependency for matplotlib, which uses numpy functions for numerical data and multi-dimensional arrays as shown in the following code snippet:
Pandas is a library used by matplotlib mainly for data manipulation and analysis. Pandas provides an in-memory 2D data table object called a Dataframe. Unlike numpy, pandas is not a required dependency of matplotlib.
For more examples of how to create plots with matplotlib, refer to How To Display A Plot In PythonThe following tutorials will provide you with step-by-step instructions on how to work with Matplotlib, including:
One major feature of the IPython kernel is the ability to display plots thatare the output of running code cells. The IPython kernel is designed to workseamlessly with the matplotlib plotting library to provide this functionality.
To set this up, before any plotting or import of matplotlib is performed youmust execute the %matplotlib magic command. Thisperforms the necessary behind-the-scenes setup for IPython to work correctlyhand in hand with matplotlib; it does not, however, actually execute anyPython import commands, that is, no names are added to the namespace.
If the %matplotlib magic is called without an argument, theoutput of a plotting command is displayed using the default matplotlibbackend in a separate window. Alternatively, the backend can be explicitlyrequested using, for example:
