Python中如何使用openpyxl插入折線圖實例

小編給大家分享一下Python中如何使用openpyxl插入折線圖實例，希望大家閱讀完這篇文章后大所收獲，下面讓我們一起去探討吧！

代碼如下：

import os
import openpyxl

from datetime import date
from openpyxl import Workbook

from openpyxl.chart import (
 Series,
 LineChart,
 Reference,
)
def add_line_chart(title, wss, min_col, min_row, max_col, max_row):
 c1 = LineChart()
 c1.title = title # 圖的標題
 c1.style = 12 # 線條的style
 c1.y_axis.title = 'percent' # y坐標的標題
 if 'IDC' not in title:
  c1.x_axis.number_format = 'd-mmm' # 規(guī)定日期格式 這是月,年格式
  c1.x_axis.majorTimeUnit = "Months" # 規(guī)定日期間隔 注意days；Months大寫
 c1.x_axis.title = "Date" # x坐標的標題
 data = Reference(wss, min_col=min_col, min_row=min_row, max_col=max_col, max_row=max_row) # 圖像的數(shù)據(jù) 起始行、起始列、終止行、終止列
 c1.add_data(data, titles_from_data=True, from_rows=True)
 dates = Reference(wss, min_col=2, min_row=1, max_col=max_col)
 c1.set_categories(dates)
 wss.add_chart(c1, "A6") # 將圖表添加到 sheet中


def save_data_to_excel(file_name, target_sheet_name):

 sheet.title = target_sheet_name
 sheet.column_dimensions['A'].width = 20
 start_date_index = 'B'
 for each_date in all_date.keys():
  sheet.column_dimensions[start_date_index].width = 13
  start_date_index = chr(ord(start_date_index) + 1)

 add_line_chart(target_sheet_name.upper() + "'s Phone Statistics", sheet, 1, 2, len(all_date.keys()) + 1,
     min(15, len(all_phone_company.keys()) + 1))

 wb.save(file_name)

補充知識：python plotly line chart 折線圖

# 1 折線圖數(shù)據(jù)
# trace1 - 基本格式
# trace2 - 更多參數(shù)
trace1 = go.Scatter(
 x = x1,
 y = y2,
)
trace2 = go.Scatter(
 x = x2,
 y = y2,
 mode = 'lines', # 模式：lines 線，markers 點?？捎谩?”相連
 name = 'line2', # 折線名，顯示于圖例
 connectgaps = True # 連接缺失點兩端 默認False
 line = dict(
  color = ('rgb(205, 12, 24)'), # 顏色
  width = 4, #線寬
  dash = 'dash') # 虛線： dash 一一，dot ···，dashdot 一·一
) 
)
 
# 2 打包數(shù)據(jù)
data = [trace1,trace2]
 
# 3 格式
layout = dict(title = '折線',
    xaxis = dict(title = '時間'), # 橫軸坐標
    yaxis = dict(title = '數(shù)量'), # 總軸坐標
    legend=dict(x=1.1,y=1) # 圖例位置 
    )
 
# 4 打包數(shù)據(jù)+格式
fig = dict(data=data, layout=layout)
 
# 5 畫圖
py.iplot(fig, filename='styled-line')
