mplfinance 中是否有等价于 plt.scatter 的东西?如何在 mplfinance 中绘制数据点图表?

is there an equivalent of plt.scatter in mplfinance? How to you graph data points in mplfinance?

mplfinance 中 plt.scatter 的等价物是什么???

我正在使用 mpl finance 绘制股票价格图。

def graph():
    file = 'prices1.xlsx'
    data = pd.read_excel(file, sheet_name = stockQuote)
    data.Date = pd.to_datetime(data.Date)
    data = data.set_index('Date')
    mpf.plot(data, type = 'candle', mav = (100), tight_layout = True)

这个

graph('AAPL')

应该给我 AAPL 烛台价格图。
我还有另一个 excel sheet 的买卖价格。看起来像这样

myPrices = pd.read_excel('transactions.xlsx')
Date Symbol Action Price
2020-03-20 AAPL Buy 80
2021-03-05 AAPL Sell 120
2020-03-20 TSLA Buy 400

我知道 matplotlib 有这个:

plt.scatter(myPrices.index, myPrices['Buy'], label = 'Buy', market = '^', color = 'green')
plt.scatter(myPrices.index, myPrices['Sell'], label = 'Sell', market = 'v', color = 'red')

因为我想绘制图表 'AAPL',所以我想读取 transaction.xlsx 中的日期,其中 Symbol = 'AAPL'。我想买的时候在MPLFINANCE GRAPH中用绿色箭头^表示,卖的时候用红色箭头v表示。但是,我只知道matplotlib中的这个方法。 mplfinance 是否有等价物?请帮忙 T-T

mplfinace 中的散点图不能单独使用,但可以与烛台结合使用。您的数据被修改为每月数据并用作样本数据。数据上需要注意一点,时序数据的长度必须相同,否则会出错。这个页面不错reference.
