这里我们使用了subplot来创建一个包含3个子图的绘图区域,并使用循环遍历数据集来生成多个Pie Chart。在每个子图中,我们使用pie函数来绘制Pie Chart,其中labels参数用于设置每个扇形的标签,autopct参数用于设置显示百分比,startangle参数用于设置起始角度。最后通过set_title来设置每个Pie Chart的标题,并通过plt.show()来展示...
importmatplotlib.cmascm #导入库 result=date.groupby(date.index.year).agg(sum=('成交笔数','sum'),avg=('换手率','mean'))#计算每年成交笔数总计值,换手率均值plt.pie(result['sum'],colors=cm.ScalarMappable().to_rgba(result['avg']),labels=result.index,autopct='%3.1f%%')#根据换手率均值设...

一.引言 因工作需求,需要绘制一些数据的饼图,使用默认的颜色绘制不够美观,下面我们找一些好看的颜色美化一些饼图。 二.颜色选择 我们根据 plt 给出的一些好看颜色对应的编码即可为每一个 pie 配置好看的颜色,通过 colors 为每一个 pie 指定颜色,博主这里简单挑选了一些比较清新的颜色,大家也可以自己把文字识别出来...
33、饼图(Pie Chart) # Import df_raw = pd.read_csv("./datasets/mpg_ggplot2.csv") plt.figure(dpi=140) # Prepare Data df = df_raw.groupby('class').size() # Make the plot with pandas df.plot(kind='pie', subplots=True, figsize=(10, 10)) ...

plt.pie(sizes, explode=explode, labels=labels, colors=colors, ...) Enhancing Your Pie Chart with a Legend To make your pie chart even more informative, consider adding a legend using the plt.legend() function. This overlays a legend on your chart, providing clarity. import matplotlib.pyplot...
8. 3D饼图(3D Pie Chart) 代码语言:javascript 复制 import matplotlib.pyplot as plt labels = ['A', 'B', 'C', 'D'] sizes = [15, 30, 45, 10] colors = ['red', 'blue', 'green', 'yellow'] explode = (0, 0.1, 0, 0) # 用于突出显示某个扇区 plt.pie(sizes, explode=explode,...
The pie function plots the pie chart. Mylabels attribute is given to the label of the pie function. Explode attribute is used to explode the part of the pie. There is also a shadow attribute in the pie function for giving a shadow effect. In legend function a loc variable is passed to...
A pie chart showing the portfolio allocation by ticker. 2. A plot to analyze historical returns and volatility of each security in the portfolio. (Not plotted if portfolio only has one security) 2. A comparison between portfolio returns and volatility against the benchmark over the specified ...
