如何使用OpenPyXL将图表标题定位(对齐)到左侧

import openpyxl
from openpyxl.drawing.text import RichText
from openpyxl.chart import BarChart, Reference

# 打开Excel文件
workbook = openpyxl.load_workbook('example.xlsx')

# 获取工作表
worksheet = workbook.active

# 创建一个柱状图
chart = BarChart()

# 设置图表标题
title = RichText()
title.text = "图表标题"
title.font.size = 14
title.font.bold = True

# 将标题定位到左侧
chart.title = title
chart.title.tx.rich.p[0].pPr.algn = "l"

# 设置图表数据范围
data = Reference(worksheet, min_col=2, min_row=1, max_col=3, max_row=5)

# 添加数据到图表
chart.add_data(data)

# 将图表添加到工作表
worksheet.add_chart(chart, "E5")

# 保存Excel文件
workbook.save('example.xlsx')
