linqy	Posted - 04/23/2024 : 12:43:18 PM 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()

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() James
