#如Rectangle 和 Circle,完整的块位于matplotlib.patches #要绘制图形,需要创建一个块对象shp,然后通过ax.add_patch(shp)将其添加到subplot中 fig = plt.figure() ax = fig.add_subplot(1,1,1) rect = plt.Rectangle((0.2,0.75),0.4,0.15,color = 'k',alpha = 0.3) circ = plt.Circle((0.7,0.2),0...
画个长方形,三角形,圆形(椭圆)。 Matplotlib有一些表示常见图形的对象,这些对象被称为块(patch)。完整的集合位于matplotlib.patches。 fig = plt.figure() ax = fig.add_subplot(111) rect = plt.Rectangle((0.2,0.75), 0.4, 0.15, color = ‘r’, alpha = 0.3)#左下起点,长,宽,颜色,α circ = plt...

目前网上较多的案例是添加左侧和底部的majortick,而由于 top 和right 轴的坐标范围发生变化,于是模仿Secondary Axis 方法,叠加新的“图层”来为顶部和右侧添加处于不同位置的 ticks,add_alt(self,**kwargs) 是专门给 proplot 改编的,如果想用matplotlib 绘制,便可以直接采用axes.Axes.secondary_xaxis 和axes.Axes....
