2. 使用plt.Circle()绘制基本圆形 Matplotlib提供了plt.Circle()函数,这是绘制圆形最直接的方法。以下是一个基本示例: importmatplotlib.pyplotaspltfrommatplotlib.patchesimportCirclefig,ax=plt.subplots()circle=Circle((0.5,0.5),0.2,fill=False)ax.add_patch(circle)ax.set_xlim(0,1)ax.set_ylim(0,1)ax....

axes = plt.subplots() draw_circle = plt.Circle((0.5, 0.5), 0.3,fill=False) plt.gcf(...
