Pgfplot 对数轴定制

我试图重现以下图片：

在此处输入图片描述

但目前我可以：

在此处输入图片描述

有很多问题：

  • 对数尺度不是对数的，即256, 512, 1020, 2050。我希望有256, 512, 1024, 2048
  • y 轴和 x 轴与原始轴完全不同

  • x网格是多余的，见原图

有点乏味，但经过大量调整后就相当接近了（阴影也是可能的，但请不要这样做。这只是一个 Excel 技巧，在我看来，对视觉没有任何帮助）：

这是你想要的？

抱歉，我太忙了，没时间多评论，不过这是代码。我想你可以自己调整一下以满足你的需求。

请注意，您的观点似乎与原始图不对应（例如，红色原始曲线中的点（128,82.638）在哪里？
