Origin Ver. and Service Release (Select Help-->About Origin):OriginPro 2022 (64-bit) SR1
Operating System: Windows 11

Hi, I am using external python and the originpro package to automatically import my data and create plots from this data.

I am now trying to add Reference Lines with a label at specific x-positions just like it is possible from the Axis dialog box under the 'Reference Lines' tab.

So far, I have only found the X-function 'addline' which I was able to call from Python but this did not allow me to have arbitrary labels for the line.

Is there a possibility to automatically add Reference lines at some given x-values with String-labels also provided from the Python program?

Thanks in advance for any help.

Could you try the Python script below?

import originpro as op
gl = op.new_graph()[0]
gl.set_int('x.reflines.count',1)
gl.set_int('x.reflines.lineshow',1)
gl.set_float('x.refline1.value',4)
gl.set_int('x.refline1.labelshow',1)
gl.set_str('x.refline1.labeltext','abc')

Nice, it works! Thank you very much for the script.

Would it also be possible to rotate the label so that they are displayed vertically?

In some of my plots the labels overlap if I add too many and having them vertically would be more space-saving.

gl.set_float('x.refline1.value',4)
gl.set_int('x.refline1.labelshow',1)
gl.set_str('x.refline1.labeltext','abc')
gl.lt_exec("RLX1.rotate=90") ## RLX1 is the object name of the label
