2.1 使用ax.invert_xaxis()方法 这是最简单直接的方法,只需要在绘图后调用ax.invert_xaxis()即可。 importmatplotlib.pyplotaspltimportnumpyasnp# 创建数据x=np.linspace(0,10,100)y=np.sin(x)# 创建图形和坐标轴fig,ax=plt.subplots()# 绘制数据ax.plot(x,y,label='sin(x)')# 反转x轴ax.invert_x...

通过设置plt.xticks()和plt.yticks()函数来控制坐标轴刻度的间隔,以及plt.tick_params()函数来设置刻度的样式: plt.xticks(np.arange(0,11,step=2))# 设置x轴刻度间隔为2plt.yticks(np.arange(-1,1.1,step=0.2))# 设置y轴刻度间隔为0.2plt.tick_params(axis='both',direction='in',length=6,width=2...

and inversely from middle to end. It should be symmetric on the increasing and decreasing side, and only differ in hue. At the ends and middle, will reverse direction, which should be smoothed in space to reduce artifacts. See [kovesi-colormaps] for more information on the design of cyclic...

Example of setting axis limits If for some reason you’d like either axis to be displayed in reverse, you can simply reverse the order of the arguments (Figure 4-13): In[10]: plt.plot(x, np.sin(x)) plt.xlim(10, 0) plt.ylim(1.2, -1.2); Figure 4-13. Example of reversing the...
