如何将'markersize'参数添加到DataFrame图中？

Question

我正在尝试绘制一个DataFrame，我想修改markersize，但是似乎无法在同一plot（）调用中完成它。

// get customers
db.getCollection('customers').aggregate([{
  $graphLookup: {
    from: "customers",
    startWith: "$dependencies.customers",
    connectFromField: "dependencies.customers",
    connectToField: "_id",
    depthField: "depth",
    as: "dependencies.customers",
    maxDepth: 5,
  }
}])


// get customersOf (reverse direction)
db.getCollection('customers').aggregate([{
  $graphLookup: {
    from: "customers",
    startWith: "$dependencies.customersOf",
    connectFromField: "dependencies.customersOf",
    connectToField: "_id",
    depthField: "depth",
    as: "dependencies.customersOf",
    maxDepth: 5,
  }
}])

我遇到错误：AttributeError：未知属性标记大小。

但是，似乎允许使用'markersize'（https://matplotlib.org/api/_as_gen/matplotlib.pyplot.plot.html），所以我不确定是什么问题。

使用scatter plot，您的size参数仅为s，请尝试：

ax0 = df_can_t.plot(kind='scatter', x='Year', y='China', \
figsize=(30,10), color = 'red', marker= '+', s = 14.0)

这是MVCE：

import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns

df = sns.load_dataset('iris')

ax = df.plot(kind='scatter', x='petal_width', y='sepal_width', s=10.0)

输出：
