Question

我已经为下面的数据绘制了条形图

                Total Monthly Actual Hours  Total Monthly Work Hours
Activity Month
Apr-19          35381.25                    42592
May-19          31722.50                    44528
Jun-19          27708.50                    38720
Jul-19          34283.50                    44528
Aug-19          21359.90                    42592

。

到目前为止我的代码

display(dfWorkActual)

dfWorkActual.plot(kind='bar')
plt.ylabel('Work Hours')
plt.xlabel('Month')
plt.title("Total Monthly Work Hours & Total Actual Work Hours vs Month")

现在我想添加总实际小时数占每月总小时数的百分比。

例如：

请告知

您可以做的是用这种方式在绘图上注释一些文本

for x,y,tex in zip(x_axis, abs_value, perc_value):
        t = ax.text(x, 
                    y, 
                    f"{tex:.2f} %", 
                    horizontalalignment='center',
                    verticalalignment='center',
                    size = 11.5, 
                    bbox = dict(boxstyle="round", 
                                fc="w", 
                                ec='#414141', 
                                linewidth=1.4))

其中x_axis是带有列所在位置的列表。 abs_value是带有列高的列表，而perc_value是带有百分比的列表。我在文本中添加了其他元素，例如bbox将创建一个带有百分比的圆形白框。试着使用参数以获得最佳效果。如您所见，我将文本f"{tex:.2f} %"放置在坐标(x, y)上。希望对您有所帮助。

要注释条形图，您可以在此处参考matplotlib文档中的示例。

https://matplotlib.org/3.1.1/gallery/lines_bars_and_markers/barchart.html#sphx-glr-gallery-lines-bars-and-markers-barchart-py

fig = plt.figure(figsize=(15,10))
ax = plt.gca()
width = 0.35
rects1 = ax.bar(df.index-width/2, df.A, width)
rects2 = ax.bar(df.index+width/2, df.B, width)
for r1, r2 in zip(rects1, rects2):
    h1 = r1.get_height()
    h2 = r2.get_height()
    percent = int(h1 * 100 / h2)
    ax.annotate('{}%'.format(percent),
                    xy=(r1.get_x() + r1.get_width() / 2, h1),
                    xytext=(0, 3),  # 3 points vertical offset
                    textcoords="offset points",
                    ha='center', va='bottom')
    ax.annotate('100%',
                    xy=(r2.get_x() + r2.get_width() / 2, h2),
                    xytext=(0, 3),  # 3 points vertical offset
                    textcoords="offset points",
                    ha='center', va='bottom')

plt.show()

和

fig = plt.figure(figsize=(15,10))
ax = plt.gca()
width = 0.35
rects1 = ax.bar(df.index, df.A, width)
rects2 = ax.bar(df.index, df.B, width, bottom=df.A)
for r1, r2 in zip(rects1, rects2):
    h1 = r1.get_height()
    h2 = r2.get_height()
    percent = int(h1 * 100 / h2)
    ax.annotate('{}%'.format(percent),
                    xy=(r1.get_x() + r1.get_width() / 2, h1/2),
                    xytext=(0, 0),
                    textcoords="offset points",
                    ha='center', va='bottom')
    ax.annotate('100%',
                    xy=(r2.get_x() + r2.get_width() / 2, h1+h2/2),
                    xytext=(0, 0), 
                    textcoords="offset points",
                    ha='center', va='bottom')

plt.show()
