plot(x, y)#用默认线型、颜色绘制折线图plot(x, y,'bo')#用蓝色的圆点标识绘制点图plot(y)#绘制折线图,x坐标用[0,1,...,N-1]表示plot(y,'r+')#点图,x坐标同上,点样式为红色、+号 我们可以用Line2D的相关属性作为参数,在绘制时控制更多效果。Line属性和fmt可以混用,以下代码给出了相同样式的两种...

In this section, we learn about how to plot or draw a vertical line in matplotlib in Python. Before starting the topic, firstly we have to understand what is avertical lineor how it looks. In general, a vertical line is a straight line that goes from top to bottom and vice versa. Or...

This time though, let’s plot it in red, with dots for each point, and a dashed line connecting them: 1 plt.plot(radius, square, marker='o', linestyle='--', color='r') Matplotlib offers a variety of options for color, linestyle, and marker. Here are a few of the most common:...
They-axisis the vertical axis. Plotting Without Line To plot only the markers, you can useshortcut string notationparameter 'o', which means 'rings'. Example Draw two points in the diagram, one at position (1, 3) and one in position (8, 10): ...
