Method#2 – Update Data for Plot There is a better and faster way of updating a plot in matplotlib. This technique does not involve clearing our plot, instead it directly updates the part that need to be updated
To update the plot on every iteration during the loop, we can use matplotlib. We constantly update the variables to be plotted by iterating in a loop and then plotting the changed values in Matplotlib to plot data in real-time or make an animation. We use a variety of approaches to visu...
plot(x,y1,color='red',linewidth=2,linestyle='--')#颜色为红色,线宽度为2,线风格为-- plt.plot(x,y2)#进行画图 plt.show()#显示图 设置坐标轴 代码语言:javascript 代码运行次数:0 运行 AI代码解释 x=np.linspace(-3,3,50) y1=2*x+1 y2=x**2 plt.figure(num=2,figsize=(8,5)) plt....

1.我们可以用画布的plot的方法直接画线, 2.也可以用画布的add_line的方法添加一个Line2D的实例, 在画布上添加一条线2dline的方法 import threading from turtle import shape import matplotlib.pyplot as plt import matplotlib.animation as animation
在这个示例中,我们绘制了三条正弦曲线,分别使用了圆点、方块和三角形作为标记。通过在plot()函数的格式字符串中指定标记类型(如‘o-‘),我们可以同时设置线型和标记类型。 3. 自定义标记大小和颜色 除了选择标记类型,我们还可以自定义标记的大小和颜色。这可以通过markersize和markerfacecolor/markeredgecolor参数来实现。
