Origin Ver. 2021b and Service Release SR2 (Select Help-->About Origin):
Operating System: Win10 Ent

Hi,

Is it possible to change the line width of a graph using External Python? Also, can a straight line be inserted with a command line like in this example: https://www.originlab.com/doc/X-Function/ref/addline?

Thank you,
Tibi

1. To set line width:
plot.set_int('line.width', 6)

2. To run Xfunction from Python, try:
op.lt_exec("addline type:=1 value:=12 select:=1 name:=vline1;")

It worked to change the line width. However, the second option, did not work. This is what I have tried:

gl_1 = gr[0]
p1 = gl_1.add_plot(wks, 1, 0, type=230) # X is col A, Y is col B. 202 is Line + Symbol.
p1.set_int('line.width', 10) # set the line width
op.lt_exec("addline type:=1 value:=0 select:=1 name:=hline1;")

gl_1.rescale()

I want an horizontal line at value 0.

Thank you,
Tibi

You may need to specify the graph layer to run the LT script, the the script below:
gl_1.lt_exec("addline type:=1 value:=12 select:=1 name:=vline1;")

If you just need to show a horizontal line at Y=0, you can turn it on from GUI and save into your template.

You can control such axes properties with set_int, like


gl_1.set_int("x.AtZero",1)


Details on such LabTalk properties can be found at

Thank you! It's working!

Appreciate your help!

I prefer this way as I want to add the zero line when certain conditions are met.
