chap-9 Output graph is rotated.

*Input graph is rotated

chap-9 uses a function from ""from kf_book.nonlinear_plots import plot_nonlinear_func"" where in the 'input' histogram the xs and ys got replaced and the graph is rotated 90 degrees clockwise. Was it intentional? I see in plot_nonlinear_func for input graph the histogram plot is written as plt.plot(h[0], h[1][1:], lw=2....) instead of plt.plot(h[1][1:], h[0], lw=2...)

Was it intentional? We are comparing the noise before and after applying nonlinear function so they should be similarly oriented to see, right? this is what it looks like

this is what it should look like(I think)
