This article mainly introduces how to use matplotlib to draw a rectangle in the coordinate system in Python, involving the techniques related to drawing graphics in the matplotlib module, for more information about how to use matplotlib to draw a rectangle in a coordinate system, see the

1. Locate the Matplotlib configuration file Matplotlibrc in the Python installation directoryMine is C:\Python27\Lib\site-packages\matplotlib\mpl-data.2. #font. Family, remove its comment, and the value after the colon changes to Microsoft Yahei3. #font. Sans-serif, remove its annotations, and add Microsoft Yahei to the front of the colon4. Copy the file.

The matplotlib Chinese garbled solution in Python, Matplotlib is a good drawing package for Python, but it does not support Chinese characters (it seems that there is no Chinese font in its default configuration), so if there is a Chinese character in the drawing, garbled characters will appear.

The first two articles briefly introduce some common methods of scientific computing numpy, and some other content that will be learned in later examples. Another module,--matplotlib, is described below.Matplotlib is a Python 2D drawing library that tries to make complex drawing visualizations easier. A few lines of code can generate drawings, histograms, power spectra, bar charts, error plots, scatter plo

Matplotlib is a common data visualization tool used in Python, and is a bit similar to MATLAB. Calls are simple and powerful. You can install it from the command line pip install matplotlib under Windows. Here are some examples of basic use: 1. Draw a straight line First generate a set of data on line y = 5 * x + 5 by NumPy and then draw it on the chart 1 Import

First, download the relevant Chinese font Simhei file:Second, find the Matplotlib data storage location by the following code:Import matplotlib Print (Matplotlib.matplotlib_fname ())My directory is: /VOLUMES/05/ANCONDA/ANACONDA3/LIB/PYTHON3.6/SITE-PACKAGES/MATPLOTLIB/MPL-DATA/MATPLOTLIBRCThird, open the above directory, and copy the downloaded font file simhei.t

Toss for a long time, summed up some.First, if Python is 64 bits, install the 32-bit numpy, Scipy, or matplotlib module.There will be a lot of problems.For example, when you import Numpy in Python, the import has a problemThere will be no path, although there is a solution, but not the root causeSo I recommend a unifie

There are many visual tools, such as tableau, a variety of JS framework, I personally feel it should be the best to learn JS, because JS does not need the environment, every computer has a browser, and like matplotlib need a development environment such as python, or more troublesome, But after all, using Python to process the data, this article is to write some

Recently obtained some four grade results data, about 500, so the whim can you see whether these results data meet the so-called normal distribution? Do it, so I have this article.The article incidentally introduces some usages of xlrd module and some methods of matplotlib to draw the bar chart and random bar chart of custom data, and provides some related links, which can be used as resources to learn matplotlib
