从数据框python绘制单独的直方图

Question

I have a data frame table "pandastable3" that looks like this:

I would like to plot histograms of values for all the columns separately, but so far I am able to get only a single figure containing all the plots together with this to plot the first 3 columns:

pandastable3.hist(layout=(1,2,3))

But I am not sure I am doing that correctly as I cannot visualize anything.

Answer 1

我想diff()为每一列给出不同的图：

pandastable3.diff().hist()
