在之前的一个问题(colobar label matplotlib in ImageGrid)中,有一种方法可以向colorbar添加标签,但是这种方法在当前版本中好像已经失效了。
我尝试过的平台有:
- Mac w/ Canopy: - python: 2.7 - matplotlib: 1.4.3-6 - Linux: - python: 2.7 - matplotlib: 1.3.1
下面是来自之前问题的代码,并加入了在iPython笔记本中运行所需的额外代码:
代码的错误消息格式如下:
自从最初的问题被提出以来,matplotlib接口有改变吗?如果是这样,我该如何添加colorbar标签?
