How to write a python program to make Fill to Data Plot directly select Data as Backgnd. My code is:

import os
import originpro as op
wks = op.find_sheet()
graph = op.new_graph(template='XPSArea')
gl=graph[0]
plot1 = gl.add_plot(f'{wks.lt_range()}!(?,5:end)', type = 'l')
plot2 = gl.add_plot(f'{wks.lt_range()}!(?,3:4)', type = 'l')
plot3 = gl.add_plot(wks,1,0,type = 's')
g1 = gl.group(True,0,wks.cols-5)
plot1.set_fill_area(type=8)
# how to select the Backgnd. data?
gl.rescale()

You may need to call LabTalk from the Python code. Please refer to the LabTalk page: https://www.originlab.com/doc/en/LabTalk/ref/Options_for_Lines#-lfp

Here's the sample code:

import os
import originpro as op
wks = op.find_sheet()
graph = op.new_graph()
gl=graph[0]
plot1 = gl.add_plot(f'{wks.lt_range()}!(?,5:end)', type = 'l')
plot2 = gl.add_plot(f'{wks.lt_range()}!(?,3:4)', type = 'l')
plot3 = gl.add_plot(wks,1,0,type = 's')
g1 = gl.group(True,0,wks.cols-5)
plot1.set_fill_area(type=8)
str = f'range rr = {plot1.lt_range()}; set rr -lfp 3;'
gl.lt_exec(str)
# how to select the Backgnd. data?
gl.rescale()
