python – Matplotlib添加一个特定的刻度线呈现轴最大 – 多个

试图将观察结果分别绘制到每次观察的多个尺度,我设法产生以下情节：

但是我想添加一个刻度,在每个刻度中显示y-max值,而不管它与前一刻度之间的差距.下面给出了这种情节的一个例子.当y-max是滴答间隔的倍数时产生.

谢谢,
F.

以下是用于生成这些示例的代码.

    # Saves some space to the right so that we can add our scales
    fig.subplots_adjust(right=1-(subplot_reduction_factor)*nb_scales)

    for (n,(vmin,vmax,color,label,alignment)) in enumerate(scales):

        # Adjust wrt. the orignial figure's scale
