好吧,所以我汇总了一堆看起来像这样的数据:

除了不是三列,而是其中的561列:-)
对我来说,这似乎是一个简单的问题:我知道如何使用 X-mean y-Mean z- Mean
1 0.3444 2.34987 1.347
2 etc.
3
4
5
6
绘制第一列与x列,因此,列名通常是一堆乱码,所以我想通过不参考名称而不是名称来绘制单个图。我想做某种Mean_f_values.plot(y= y_vals, use_index=True).
循环并显示几张图,以尝试清除无用的列。但是(到目前为止),我只能找到列名,而在绘制时只能引用它们的位置。在我看来,这至少在某种简单的绘图方法中是不正确的。我有点菜鸟,所以我想念什么?谢谢!
