plot() 函数只是 Matplotlib 库中最简单的绘图函数,除了横坐标x、纵坐标y外,它还可以通过关键字参数c(color) 控制线条的颜色,比如plt.plot(x,y1,c="y")可以使上图中曲线 sin(x) 的颜色变成黄色,通过关键字参数s(size) 控制线条的粗细等,有具体需求的时候可以查对应的的 API 手册。 pyplot 模块中其他

1.plot() plot(x,y) plots each vector pairs (x,y) 画图函数画出每个点 每组变量 plot (y) plots each vector pairs(x,y),where x=[1...n],n=length(y) 仅有一个变量时 仅画出 当x=整数点时的对应y值得点 example: plot (cos(0:pi/20:2*pi)); ...
在MATLAB中,使用plot()函数绘制图线,其语法为: none plot(x,y,LineSpec) 各参数意义如下: x: 图线上点的x坐标 y: 图线上点的y坐标 LineSpec: 图线的线条设定,三个指定线型,标记符号和颜色的设定符组成一个字符串,设定符不区分先后.具体细节请参考官方文档. ...
matlab绘制点绘制点是matlab最基础的操作,也是绘制线、面、体的基础 二维点二维点有两种绘制方式:plot和scatter plot(x,y)x,y为对应点的横纵坐标。因为plot会默认化成线,所以需要添加对… 无忌不悔发表于matla... MATLAB 线图plot以及图窗,坐标轴的设置等 plot 函数为MATLAB中最最常用的作图函数之一,简单介绍plo...
Then, create a scatter plot. Get x = linspace(0,3*pi,200); y = cos(x) + rand(1,200); scatter(x,y) Vary Circle Size Copy Code Copy Command Create a scatter plot using circles with different sizes. Specify the size in points squared Get x = linspace(0,3*pi,200); y = ...
Function to plot, specified as a function handle to a named or anonymous function. Specify a function of the form y = f(x). The function must accept a vector input argument and return a vector output argument of the same size. Use array operators instead of matrix operators for the best...
plot(G) plots the nodes and edges in graph G. example plot(G,LineSpec) sets the line style, marker symbol, and color. For example, plot(G,'-or') uses red circles for the nodes and red lines for the edges. example plot(___,Name,Value) uses additional options specified by one or ...
