Foreword In data visualization, it is often necessary to partially enlarge the data in a certain interval to obtain a higher contrast visualization effect. The following uses the Matplotlib library of the Python language to implement a simple partial magnification effect. Dependent libraries matplotlib: plotting library numpy: an extended library that supports a large number […]

Implementation steps of MATLAB panorama cutting and box plot display
Reference: Implementation steps of MATLAB panoramic cutting and box plot display | w3cschool notes In the field of photography, panorama is a photography technology that can capture all the surrounding 360-degree scenes, but the actual look and feel of panorama is not that good (see the example of panorama below). We can use matlab to […]
Matplotlib_plotting canvas configuration
Canvas Configuration plt.figure() figsize:canvas size, width and height #Import the two libraries numpy and matplotlib.pyplot import numpy as np import matplotlib.pyplot as plt #Created a graphics window with a size of 5×3 inches. plt.figure(figsize=(5, 3)) # Draw sine curve x = np.linspace(0, 2*np.pi) y = np.sin(x) plt.plot(x, y) plt.show() If the canvas size is changed […]
Characterizing time series using recurrence plot
In this article, I will show how to use Recurrence Plots to describe different types of time series. We will look at various simulated time series with 500 data points. We can visually characterize a time series by visualizing its recurrence plot and comparing it to other known recurrence plots of different time series. Recursive […]
echart implements map exploration and displays scatter plots
Introduction: Realize provincial level (Henan as an example) exploration and display scattered points while the data remains unchanged. Completed picture: 1. Prepare map geoJSON, DataV.GeoAtlas geographic gadget series Create a tool function: introduce all the files in the directory, pass in the place name and return the geoJson of the place (dynamic references are used […]

matplotlib draws multi-tree dendrogram
Directory code Effect Due to the needs of answering questions, etc., sometimes we need to visualize a tree structure to debug intuitively. Here I use in Python The matplotlib library implements a function for dendrogram visualization plotTree(). This function receives the root node root of the tree and the tuple edges of the edges. It […]
