Plotting Area plots with x axis formatting

Question

I have the following code:

population = pd.DataFrame(data = population)
fig, ax = plt.subplots(figsize = (10, 5))
population.columns = ['pop']
# ax.area(population['pop'], kind ='area')
# ax = population.plot.area()


ax.fill_between: ax.fill_between(population.index, population['pop'], alpha=0.3, label='Population')
ax.xaxis.set_major_locator(md.YearLocator())
ax.xaxis.set_major_formatter(md.DateFormatter('%Y'))
plt.setp(ax.xaxis.get_majorticklabels(), rotation = 90)
ax.set_xlim([population.index[0], population.index[-1]])
ax.fill_between(population['pop'],0)

This makes the following plot:

How can i plot an area plot. If i do this:

ax.plot(population['pop'], kind ='area')

I get the following error:

AttributeError: 'Line2D' object has no property 'kind'

If i do this:

ax = population.plot.area()

It leaves the entire formatting on the x-axis. How can i plot area? Edit:

I get the following plot

For legend:

I added the following line:

ax.fill_between: ax.fill_between(population.index, population['pop'], alpha=0.3, label='Population')

As you can see there is no legend

Try `ax.fill_between(population.index, population['pop'],0)` in your first solution. — JohanC, Jul 10 '20 at 20:59

Instead of ax.plot(), use ax.fill_between():

plt.fill_between(your_x_list, your_y_list, label=your_label)

Can you post the result? – Red Jul 10 '20 at 21:06

@Slartibartfast You need to call `ax.legend()` to see the legend – JohanC Jul 10 '20 at 21:08
@JohanC It prompts: `No handles with labels found to put in legend.` – Slartibartfast Jul 10 '20 at 21:08

You need to set a label in the call to `ax.plot` and/or `ax.fill_between`: `ax.fill_between(population.index, population['pop'], alpha=0.3, label='Population')` – JohanC Jul 10 '20 at 21:11
@JohanC There is no legend that shows up. I have also updated the code. – Slartibartfast Jul 10 '20 at 21:18
@AnnZen `ax.legend([population], ['population'])` Even with this there is no legend – Slartibartfast Jul 10 '20 at 21:19

@Slartibartfast You need to call `plt.legend()`, with no parameters. – Red Jul 10 '20 at 21:19
