As multiple functions can be drawn in a single plot; ‘labels’ are the way to provide information about different functions in the plot and labels are created using ‘Legends’ in Python. Examples to Implement Matplotlib Legend Let us now understand how to create plots and give them labels,...
To place the visually appealing legends in matplotlib, we need to follow a few easy steps:Create a plot using the plot() function from matplotlib.pyplot module. Add a label to the plot. Labels represent the name of the plot for the x and y axis respectively. Use the legend() function ...
1. 导入Matplotlib库 在Python中,我们需要先导入Matplotlib库,然后在代码中使用它。 importmatplotlib.pyplotasplt 2. 绘制第一条线形 使用Matplotlib的plt.plot()函数可以在画布上绘制线条。这是绘制第一条线形的代码示例: # 创建一个简单的数据集x =[1,2,3,4]y =[2,4,6,8]# 在画布上绘制第一条线形p...
If we do the same thing, but use the bbox_to_anchor keyword argument we can shift the legend slightly outside the axes boundaries: import matplotlib.pyplot as plt import numpy as np x = np.arange(10) fig = plt.figure() ax = plt.subplot(111) for i in xrange(5): ax.plot(x, ...
More on PythonHow to Generate Subplots With Python's Matplotlib Placing the Legend Outside of the Plot in Matplotlib In order to place the legend outside of the plot, let’s say at the center of the right side, we need to do two things. ...
Lines and points have different colors, and they need to be displayed in the legend accordingly. The following code snippet draws only shapes and text in the legend. library(ggplot2) plot( 0, type = "n", xlim = c(0,5), ylim = c(0,5) ) A <- matrix( c( c(4,1,3,2), c(...
Add a Legend to the 3D Scatter Plot in Matplotlib Legend is simply the description of various elements in a figure. We can generate a legend of scatter plot using thematplotlib.pyplot.legendfunction. importnumpyasnpimportmatplotlib.pyplotasplt x=[1,2,3,4,5]y1=[i**2foriinx]y2=[2*i+...
How to add a legend to the plots? For example, if using several moving averages it will be useful to show a legend to map moving averages to line plots. Is clear how this is done using matplotlib but I did not see an example of how to do...
Matplotlib histogram is used to visualize the frequency distribution of numeric array. In this article, we explore practical techniques like histogram facets, density plots, plotting multiple histograms in same plot.
A bar chart with one bar for each student is generated with this code. Each bar’s height signifies the student’s grade. By altering the bar’s color (for example: red, blue, or green), size, and arrangement, we can change the plot. We might also include a legend to make it easi...
