使用到的set_title()参数有很多,介绍几个常用的 fontsize:默认12,可选参数还有'xx-small', 'x-small', 'small', 'medium', 'large','x-large', 'xx-large' backgroundcolor:背景颜色 fontweight:字体粗细,可选参数为'light', 'normal', 'medium', 'semibold', 'bold', 'heavy', 'black' color:...

使用ax.set_title("Title"),为每个子图设置单独的标题,其中ax是一个Axes对象。 fig,axs=plt.subplots(2,1)x=[1,2,3,4,5]y1=[2,4,6,8,10]y2=[1,3,5,7,9]axs[0].plot(x,y1)axs[0].set_title("Plot 1")axs[1].plot(x,y2)axs[1].set_title("Plot 2")plt.tight_layout()plt.sho...

set_xlabel & set_ylabel:在Axes对象上设置轴标签。 ax.set_xlabel('X Axis Label') ax.set_ylabel('Y Axis Label') set_xlim & set_ylim:在Axes对象上定制轴范围。 ax.set_xlim(0,10) ax.set_ylim(-1,1) set_xticks & set_yticks:在Axes对象上指定刻度。
plt.ylim() -> ax.set_ylim() plt.title() -> ax.set_title() 在面向对象接口画图的时候,不需要单独调用这些函数,使用ax.set()方法一次性设置即可: x = np.linspace(0,10,100) ax = plt.axes() ax.plot(x,np.sin(x)) ax.set(xlim=(0,10),ylim=(-2,2),xlabel='x',ylabel='sin(x)'...
