![]() Here, we added the y-axis value of the point as its label for each point on the scatter plot. Scatter plots with a legend Matplotlib 3.7. import matplotlib.pyplot as plt x 1,2,3,4 y 4,1,3,6 plt.scatter (x, y, c'coral', label'Class 1') x 5,6,7,8 y 1,3,5,2 plt.scatter (x, y, c'lightblue', label'Class 2') plt.legend () plt.title ('Nuage de points avec Matplotlib') plt.xlabel ('x') plt.ylabel ('y') plt.savefig ('ScatterPlot09.png') plt. Plt.text(xi, yi, yi, va='bottom', ha='center') To label each point on the scatter plot, use the () function for each point in the plot. Example 2 – Label Each Point on the Scatter Plot Here, we used the va parameter to set the vertical alignment of the text to ‘center’ and the ha parameter to set the horizontal alignment to ‘center’ as well. For example, you can adjust the vertical and the horizontal alignment of the text, you can rotate the text, etc. You can customize the way the text label appears by using additional arguments. For example, let’s label the point (2014, 62.33). In case you only want to label a specific point (or points), use the () function only for those points. Output: Example 1 – Label a point on the scatter plot ![]() coding: UTF-8 - import matplotlib.pyplot as plt If you have not installed this library, you can read this tutorial to learn how to install. Preliminaries We should import python matplotlib library. First, we will create a simple scatter plot. In this tutorial, we will introduce how to create a scatter plot with labels for python beginners. Let’s now look at some examples of using the above syntax. Now to add labels to each point in the scatter plot, use the () function for each point (x, y) and add its appropriate label. We also add a colorbar with a custom title using the lorbar function, and add labels to the axes using the mlab.axes function. Customizing Scatter Plot in Matplotlib You can change how the plot looks like by supplying the scatter () function with additional arguments, such as color, alpha, etc: ax.scatter (x df 'Gr Liv Area', y df 'SalePrice', color 'blue', edgecolors 'white', linewidths 0.1, alpha 0. # add text, s to a point at (x, y) coordinate in a plot In the above code, we customize the plot by setting the minimum and maximum values of the scalar field using the vmin and vmax parameters of the function. The following is the syntax – import matplotlib.pyplot as plt The () function is used to add text at the location (x, y) in the plot. You can use the () function to label points in a matplotlib scatter plot. You can add labels to each data set that you plot using the label keyword. How to annotate points on a scatter plot in matplotlib? from matplotlib import pyplot as plt import numpy as np create a quadratic. y and add a horizontal line that represents the average y-value: import matplotlib.pyplot as plt import numpy as np create scatter plot plt.scatter(df.x, df.y) add horizontal line at mean value of y plt.axhline(ynp.nanmean(df. ![]() Import matplotlib.pyplot as plt import matplotlib.patches as mpatches import numpy as np x = y = categories = np.array() colormap = np.array() plt.scatter(x, y, s=100, c=colormap) pop_a = mpatches.Patch(color='#0b559f', label='Population A') pop_b = mpatches.Patch(color='#89bedc', label='Population B') plt.legend(handles=) plt.title('Nuage de points avec Matplotlib') plt.xlabel('x') plt.ylabel('y') plt.savefig('ScatterPlot_10.png') plt.In this tutorial, we will look at how to label points on a scatter plot in Matplotlib with the help of some examples. We can use the following code to create a scatter plot of x vs. This article will discuss how to label each point in the scatter plot in Matplotlib. Import matplotlib.pyplot as plt x = y = plt.scatter(x, y, c='coral', label='Class 1') x = y = plt.scatter(x, y, c='lightblue', label='Class 2') plt.legend() plt.title('Nuage de points avec Matplotlib') plt.xlabel('x') plt.ylabel('y') plt.savefig('ScatterPlot_09.png') plt.show() Add a legend to a scatter plot using "Proxy artists" How to create a simple scatter plot using matplotlib import matplotlib.pyplot as plt x 1,2,3,4,5,6,7,8 y 4,1,3,6,1,3,5,2 size 100,500,100,500,100,500,100,500 plt.scatter (x,y,ssize) plt.title ('Nuage de points avec Matplotlib') plt.xlabel ('x') plt.ylabel ('y') plt.savefig ('ScatterPlot02.png') plt. Matplotlib allows us to annotate the scatter plot using several methods. ![]() How to add a legend for a scatter plot in matplotlib ? Add a legend to a scatter plot using "Proxy artists".
