使用 x 轴格式绘制区域图

Question

我有以下代码：

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)

这使得下面的情节：

如何绘制面积图。如果我这样做：

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

我收到以下错误：

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

如果我这样做：

ax = population.plot.area()

它将整个格式保留在 x 轴上。我如何绘制区域？ 编辑：

我得到以下情节

图例：

我添加了以下行：

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

如你所见，没有传说

Answer 1

用ax.fill_between()代替ax.plot()：

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