脉冲星假信号频率的相对路径论证。 首先看一下演示结果: 实例代码: import numpy as np import matplotlib.pyplot as plt import matplotlib.animation as animation # Fixing random state for reproducibility np.random.seed(19680801) # Create new Figure with black background fig = plt.figure(figsize=(8,8),facecolor='black') # Add a subplot with no frame ax = plt.subplot(111,frameon=False) # Generate random data data = np.random.uniform(0,1,(64,75)) X = np.linspace(-1,data.shape[-1]) G = 1.5 * np.exp(-4 * X ** 2) # Generate line plots lines = [] for i in range(len(data)): # Small reduction of the X extents to get a cheap perspective effect xscale = 1 - i / 200. # Same for linewidth (thicker strokes on bottom) lw = 1.5 - i / 100.0 line,= ax.plot(xscale * X,i + G * data[i],color="w",lw=lw) lines.append(line) # Set y limit (or first line is cropped because of thickness) ax.set_ylim(-1,70) # No ticks ax.set_xticks([]) ax.set_yticks([]) # 2 part titles to get different font weights ax.text(0.5,1.0,"MATPLOTLIB ",transform=ax.transAxes,ha="right",va="bottom",family="sans-serif",fontweight="light",fontsize=16) ax.text(0.5,"UNCHAINED",ha="left",fontweight="bold",fontsize=16) def update(*args): # Shift all data to the right data[:,1:] = data[:,:-1] # Fill-in new values data[:,0] = np.random.uniform(0,len(data)) # Update data for i in range(len(data)): lines[i].set_ydata(i + G * data[i]) # Return modified artists return lines # Construct the animation,using the update function as the animation # director. anim = animation.FuncAnimation(fig,update,interval=10) plt.show() 脚本运行时间:(0分0.065秒) 总结 以上就是本文关于Python模拟脉冲星伪信号频率实例代码的全部内容,希望对大家有所帮助。感兴趣的朋友可以继续参阅本站其他相关专题,如有不足之处,欢迎留言指出。感谢朋友们对本站的支持!
