Python colorbar中的裁剪扩展标记

在使用

tourtf

时，我必须使用

extend='min'

，将低于给定范围的值（负值）着色。我想问一下如何裁剪这个扩展标记（箭头所指）

把它做成这样

谢谢

您可以使用以下代码：

bounds = [5*i for i in range(13)]
cax = fig.add_axes([.918, 0.175, 0.045, 0.6])
fig.colorbar(mpl.cm.ScalarMappable(cmap = 'Spectral', norm = norm),
             cax = cax,
             ticks = bounds,
             boundaries = [0] + bounds[1:-1] + [60])

bounds = [5*i for i in range(13)]
cax = fig.add_axes([.918, 0.175, 0.045, 0.6])
fig.colorbar(mpl.cm.ScalarMappable(cmap = 'Spectral', norm = norm),
             cax = cax,
             ticks = bounds,
             boundaries = [0] + bounds[1:-1] + [60])
