[Feature Request] Plot T/F mask directly as ones and zeros
#### Code Sample, a copy-pastable example if possible

```python
x = pd.Series([False,True,True,False])
x.plot()
# Error thrown!
# Running version 0.24.2
```
#### Problem description

It would be nice to be able to directly use .plot() on true / false masks. Matplotlib currently supports plotting true / false masks with the below code (using the same x variable as above): 

plt.plot(x.index, x.values)

#### Expected Output

Would be great if the code in the "code sample" section outputted the same as the matplotlib equivalent of ( plt.plot(x.index, x.values)  ), where True translates to 1, and False to zero, and plots against the index values of the series. 

#### Output of ``pd.show_versions()``
