How To Set Properties of Line Graphic Elements Using xlwings?

Method

By referencing the `Format.Line` property of a Series object, a `LineFormat` object is returned, representing the line object in the series. The members of the `LineFormat` object are used to set the line properties.

sht.api.Range(‘A1:B7’).Select()

cht=sht.api.Shapes.AddChart().Chart

ser2=cht.SeriesCollection(‘P2’)    #Second series

ser2.ChartType=xw.constants.ChartType.xlLine    #Line chart

ser2.Smooth=True    #Smooth processing

ser2.MarkerStyle=xw.constants.MarkerStyle.xlMarkerStyleTriangle    #Markers

ser2.MarkerForegroundColor=xw.utils.rgb_to_int((0,0,255))    #Color

ser2.HasDataLabels=True    #Data labels

Example

  
Code

#Line chart element settings

import xlwings as xw
import os

root = os.getcwd()
app = xw.App(visible=True, add_book=False)
wb=app.books.open(root+r'/P1P2.xlsx',read_only=False)
