10. 极坐标图(Polar Plot) 使用极坐标而不是直角坐标来显示数据,常用于显示周期性数据 代码语言:javascript 复制 import numpy as np import matplotlib.pyplot as plt # 创建角度数据和半径数据 theta = np.linspace(0, 2*np.pi, 100) r = np.sin(3*theta) # 绘制极坐标图 plt.polar(theta, r) # ...
subplot(111, projection='polar') plt.plot(theta, np.sin(5 * theta), "g-") plt.plot(theta, 0.5 * np.cos(20 * theta), "b-") plt.show() def plotting_surface(): """ 3d 曲面图 """ x = np.linspace(-5, 5, 50) y = np.linspace(-5, 5, 50) X, Y = np.meshgrid(x, ...
theta = 2 * np.pi * r fig, ax = plt.subplots(subplot_kw={'projection': 'polar'}) ax.plot(theta, r) ax.set_rmax(2) ax.set_rticks([0.5, 1, 1.5, 2]) # Less radial ticks ax.set_rlabel_position(-22.5) # Move radial labels away from plotted line ax.grid(True) ax.set_tit...
matplotlib.pyplot.rgrids(*args, **kwargs) Get or set the radial gridlines on a polar plot. get or set 径向网格线 call signatures: lines, labels = rgrids() lines, labels = rgrids(radii, labels=None, angle=22.5, **kwargs) When called with no arguments, rgrid() simply returns the ...
第二个参数:projection : {None, ‘aitoff’, ‘hammer’, ‘lambert’, ‘mollweide’, ‘polar’, ‘rectilinear’, str}, optional 可选参数:可以选择子图的类型,比如选择polar,就是一个极点图。默认是none就是一个线形图。 第三个参数:polar : boolean, optional 如果选择true,就是一个极点图,上一个参...
Get or set the theta locations of the gridlines in a polar plot. get or set 极角轴显示刻度。 If no arguments are passed, return a tuple (lines, labels) where lines is an array of radial gridlines (Line2D instances) and labels is an array of tick labels (Text instances): ...
一、plt.polar() 该函数主要负责绘制极坐标曲线,基本语法: plt.polar(theta,r,其它参数) 其中theta代表角度,r代表半径。这里的角度采用弧度制。 在设置曲线的其余参数同plt.plot()。 这里绘制一个粉色的笛卡尔心形曲线 plt.figure(1);theta=np.arange(0,2*np.pi,np.pi/100);rho=(1-np.sin(theta));plt...
Line Plot Here's how to create a line plot with text labels usingplot(). ../../_images/sphx_glr_simple_plot_0011.png Simple Plot Multiple subplots in one figure Multiple axes (i.e. subplots) are created with thesubplot()function: ...

一、绘制折线图(plot函数) plt.plot(x,y,color,line_style,line_width,marker,markeredgecolor,markeredgwidth,markerfacecolor,markersize,label) marker表示折线图中每点的标记物形状,主要有如下参数值可选: 还有一些marker相关的参数: # 导入模块 import matplotlib.pyplot as plt # 建立坐标系 plt.subplot(1,1,...
