plt.scatter(x, y, c='r', marker='o') 添加标题和标签 plt.title("Scatter Plot Example") plt.xlabel("X axis") plt.ylabel("Y axis") 显示图形 plt.show() 三、Turtle模块的使用 Turtle是Python内置的一个模块,适合用于教育目的,帮助初学者理解编程概念和简单绘图。以下是如何使用Turtle进行绘图的步骤。
matplotlib库 matplotlib是一个广泛使用的Python绘图库,它提供了丰富的绘图功能,可以绘制各种类型的图表,包括折线图、散点图、柱状图等,要使用matplotlib库,首先需要安装并导入该库: import matplotlib.pyplot as plt 绘制折线图 要绘制折线图,可以使用plot函数,以下是一个简单的示例: x = [1, 2, 3, 4, 5] y ...
Example 1: Draw Plot with Circle Using Base R & plotrix Package In this example, I’ll explain how to draw a Base R plot with circles. Consider the following scatterplot: plot(data$x, data$y)# Draw Base R plot without circle
In this example, I’ll show how to use the basic installation of the R programming language to draw a colored scatterplot in R.For this, we have to use the plot function and the col argument as shown below:plot(data$x, # Draw Base R plot data$y, pch = 16, col = data$group)...
