Origin Ver. and Service Release (Select Help-->About Origin):2024b
Operating System: Win10
Hello,
I'm creating an automation tool in Python to generate graphs in OriginLab. I've successfully added a right Y-axis and specified its range. However, I'm unsure how to modify the axis title for this right Y-axis.
=======================
import originpro as op
import numpy as np
op.set_show(True)
book = op.new_book('w', 'MyBook')
wks = book.add_sheet('SPACE')
x = np.linspace(0, 10, 100)
y1 = np.sin(x)
y2 = np.cos(x) + 1
wks.from_list(0, x, 'Time')
wks.from_list(1, y1, 'Sin(x)')
wks.from_list(2, y2, 'Cos(x)')
graph = op.new_graph()
layer1 = graph[0]
plot1 = layer1.add_plot(wks, coly=1, colx=0)
plot1.color = (255, 0, 0)
plot1.name = 'Sine Curve'
layer1.lt_exec(f'set {plot1.name} -w 2000')
layer2 = graph.add_layer(2) # 2: right Y linked X scale
plot2 = layer2.add_plot(wks, coly=2, colx=0)
plot2.color = (0, 0, 255)
plot2.name = 'Cosine Curve'
layer2.lt_exec(f'set {plot2.name} -d 2')
layer2.lt_exec(f'set {plot2.name} -w 1000')
layer1.rescale()
layer2.rescale()
layer1.axis('x').title = 'Transient Time, sec.'
layer1.axis('x').limits = (0, 10, 1)
layer1.axis('y').title = 'Left value'
layer1.axis('y').limits = (-1.0, 1.0, 0.2)
layer2.axis('y').limits = (0, 2.0, 0.2)
layer2.axis('y').title = 'Right value'

It seems the Python code does not support setting the right Y-axis title. As a workaround, you can use LabTalk to set the title. Please replace the last line with:
layer2.lt_exec('label -yr Right value')
