我正在为随机游走模型编写代码,我使用plt.axes().get_xaxis().set_visible(False)
来隐藏轴,但是当我运行程序时,绘图仍然显示两个轴。以下是我写的:
import matplotlib.pyplot as plt from random_walk import RandomWalk # Keep making random walks, as long as the program is active while True: rw = RandomWalk() rw.fill_walk() point_numbers = list(range(rw.num_points)) plt.scatter(rw.x_values, rw.y_values, c=point_numbers, cmap=plt.cm.Blues, edgecolors='none', s=10) # Emphasize the first and last points. plt.scatter(0, 0, c='green', edgecolors='none', s=50) plt.scatter(rw.x_values[-1], rw.y_values[-1], c='red', s=50) # Remove the axes. plt.axes().get_xaxis().set_visible(False) plt.axes().get_yaxis().set_visible(False) plt.show() keep_running = input("Make another walk? (y/n): ") if keep_running == 'n': break
你可以用plt.gca().get_xaxis().set_visible(False)
代替plt.axes().get_xaxis().set_visible(False)
。
下面是一个代码示例:
import matplotlib.pyplot as plt from random_walk import RandomWalk # 解决不能显示中文 plt.rcParams['font.sans-serif'] = ['SimHei'] plt.rcParams['axes.unicode_minus'] = False while True: # 创建一个RandomWalk实例,并绘制 rw=RandomWalk() rw.fill_walk() points_numbers=list(range(rw.num_points)) # 设置图表标题,并给坐标轴加上标签 plt.title("随机漫步图", fontsize=24) plt.scatter(rw.x_values,rw.y_values,c=points_numbers,cmap=plt.cm.Blues,edgecolors='none',s=15) # 隐藏坐标轴 plt.gca().get_xaxis().set_visible(False) plt.gca().get_yaxis().set_visible(False) #plt.show() plt.savefig('sjmb.png',bbox_inches='tight') keep_running=input("是否要再模拟一次随机漫步?(y/n):") if keep_running=='n': break
