Bug in plot_cross_val_selection method

[karitonov]

plot_grid_search.py

line 20:
results = pd.DataFrame(grid_search.cv_results_)[15:]
line 37-38:
plt.xticks(range(len(results)), [str(x).strip("{}").replace("'", "") for x
in grid_search.cv_results_['params']],

In line 37-38, an error occurs because the length of results and grid_search.cv_results_['params']] does not match.

Therefore, the line number 20 is corrected as follows.

results = pd.DataFrame(grid_search.cv_results_)#[15:] comment out

And then, add the following rows to some suitable places (For example, after the 41st line.).

plt.xlim(14.5, 36)

Thank you for your cooperation.

The above method is better, so I will withdraw.
