所以我想要的是把这个峰值位置值放在每个峰值的顶部，而不是菱形标记。如果我使用annotate，那么对所有的peak来说都会很累。有没有更简单的方法 如果您想给出峰值位置值的视觉线索，您可以用替换
ax.plot（a，b，'D'）例如：
ax.scatter(a, b, s=3*peak_position_value)
ax.annotateax.textab峰值位置值中的一个[]
）
我不明白为什么这么累。还有一行可以注释所有的峰值。对于zip（a，b）中的i，j:ax.annotate（str（c），ab=（i，j））fig.show（）我已经尝试了这几行，没有luckwhat是c
？它是在什么地方定义的吗？c实际上是你答案的峰值位置值。但这是可行的。不确定annotate有什么问题。这里唯一的问题是这些值不是动态的。拉伸绘图窗口时，值保持与以前相同的位置。在我的系统（Kubuntu 12.04、python 2.7、matplotlib 1.2.1）中，无论我做什么（缩放、调整大小），注释都保持附着在点上。确保xycoords='data'
和/或textcoords='data'
