我能够xlsxwriter在 Python 中按线属性生成图形。但我需要在特定值上加上 4 个点（菱形）。谁能建议我如何使用xlsxwriter.
如果需要，我也可以发布代码。
from openpyxl import load_workbook
from xlsxwriter.workbook import Workbook
import math
def graph(headline,table_percentage,table_threashold):
"""Create Graph Chart"""
wb = load_workbook(filename = 'sample.xlsx')
worksheet_final = wb.get_sheet_by_name(name='test')
workbook = Workbook('graphs.xlsx')
worksheet = workbook.add_worksheet()
heading =['test1','test2','test3','test4','test5']
worksheet.write_row('A1',heading)
count =2
while(count < worksheet_final.get_highest_row()):
data_x = worksheet_final.cell(row = count, column = 1).value
data_y = worksheet_final.cell(row = count, column = 2).value
data_s1 = worksheet_final.cell(row = count, column = 8).value
data_d0 = worksheet_final.cell(row = count, column = 14).value
data_d1 = worksheet_final.cell(row = count, column = 20).value
worksheet.write(count,0,round(data_x,0))
worksheet.write(count,1,data_y)
worksheet.write(count,2,data_s1)
worksheet.write(count,3,data_d0)
worksheet.write(count,4,data_d1)
count = count + 1
# Create a new chart with properties object.
chart = workbook.add_chart({'type': 'line'})
cellname = headline
chart.set_title({'name':cellname})
chart.set_x_axis({'name':'CLK-D Time (ps)',
'name_font':{'size':14,'bold':True},
})
chart.set_y_axis({'name':'CLK-Q Time (ps)',
'name_font':{'size':14,'bold':True},
})
chart.set_size({'width': 720, 'height': 576})
# Add a series to the chart.
chart.add_series({
'categories' : '=Sheet1!$A$2:$A$503',
'values': '=Sheet1!$B$1:$B$503',
'name':'clk2q0_S',
'line':{'color':'blue'},
})
chart.add_series({
'categories' : '=Sheet1!$A$2:$A$503',
'values': '=Sheet1!$C$1:$C$503',
'name':'clk2q1_S',
'line':{'color':'red'}})
chart.add_series({

'values': '=Sheet1!$E$1:$E$503',
'name':'clk2q1_H',
'line':{'color':'red'}})
# Insert the chart into the worksheet.
worksheet.insert_chart('K1', chart)
workbook.close()
if __name__ == '__main__':
table_percentage = "5%"
table_threashold = {}
#Need to put dot on the below 4 value
table_threashold ['setup_mt1'] = [5,210]
table_threashold ['setup_mt0'] = [-105,140]
table_threashold ['hold_mt0'] = [-39,143]
