missing from current font. FigureCanvasAgg.draw(self)

まず、提供された Python スニペットを実行し、mplfinance と Matplotlib が設定された SimHei フォントをどのように扱うかを調べます。中国語のタイトルが報告されたグリフ欠落警告なしでレンダリングされるかを確認し、PyCharm の backend パスは無視する環境コンテキストとして扱います。

Ask anything you want about mplfinance usage, project philosophy and/or priorities, or anything else related to mplfinance.

import mplfinance as mpf
import pandas as pd
import matplotlib.pyplot as plt

# 设置 matplotlib 的默认字体为 SimHei
plt.rcParams['font.family'] = 'SimHei'

# 假设您有以下 DataFrame 形式的数据
df = pd.DataFrame({
    'Date': ['2023-01-01', '2023-01-02', '2023-01-03', '2023-01-04', '2023-01-05', '2023-01-06', '2023-01-07'],
    'Open': [100, 102, 98, 101, 99, 103, 104],
    'High': [101, 104, 100, 102, 101, 105, 106],
    'Low': [99, 100, 97, 99, 97, 101, 102],
    'Close': [100, 101, 99, 100, 100, 103, 104]
})

# 将日期列转换为 datetime 格式并设置为索引
df['Date'] = pd.to_datetime(df['Date'])
df.set_index('Date', inplace=True)

# 绘制 K 线图
mpf.plot(df, type='candle', figsize=(12, 6), title='K 线图')
