停止 tikzpicture 图形上坐标标签重叠

我在 tikz 上绘制图表，由于点靠得很近，每个坐标（本例中为参考）的标签重叠。有没有办法定义每个点的每个标签的锚点位置？

谢谢！

\begin{axis}[

ylabel={I$_{ON}$/I$_{OFF}$}

代码的当前结果。

答案1

这里混合了几个答案，比如这个和这个--- 我使用散点图；我添加了类来更改点的颜色以便识别它们，然后根据表中的列添加锚点。您必须手动更改它 --- 这是标签的锚点范围；0意味着标签将位于左侧、-90上方等等。

我没有参考资料，所以所有内容都[?]在这里；您可能需要在输入实际数字时手动调整标签位置。
