Origin Ver. 2021b and Service Release SR2 (Select Help-->About Origin):
Operating System: Win10 Ent
Is it possible to use a code to export a graph from Origin to PDF?
Thank you! |

I have tried the first solution but it did not work. I am getting the following error: AttributeError: 'NoneType' object has no attribute 'save_fig'
This is the code I use:
gr1 = op.new_graph(template=(new_path_template + '\\Origin templates\\htcd_12.otpu'), lname=f'{title_spectra.group()} and {title_base.group()}')
gls = [gr1 for i in range(len(htcd_file.columns)-1)]
p = ['' for i in range(len(htcd_file.columns)-1)]
p_base = ['' for i in range(len(htcd_file.columns)-1)]
for i in range(len(htcd_file.columns)-1):
p[i] = gr1[i].add_plot(wks, coly=f'{i+1}', colx='A')
p_base[i] = gr1[i].add_plot(wks_baseline, coly=f'{i+1}', colx='A')
p_base[i].color = "Blue"
gls[i].xlim = (min_wavelength, max_wavelength)
g = op.find_graph('gr1')
g.save_fig()
I have tried the second option as well which did not throw out any error, but I don't know either the name or the location of the file.

Hello,
You can use the originpro function save_fig().
e.g.
g = op.find_graph('graph1')
g.save_fig('C:\\ExportFolder\\' + 'Image.pdf', width=500)
https://docs.originlab.com/originpro/classoriginpro_1_1graph_1_1GPage.html#abc11d7878e4df6a2b8e91f4d8bf73958
Or you could use the originpro function lt_exec() to run the LabTalk command for graph exports.
e.g.
op.lt_exec('expGraph type:=pdf')

Hello,
find_graph() uses the Short Name of the graph. I don't think you have a graph with the Short name 'gr1'.
Also, your code currently doesn't specify the filename or format.
You will want to put something like: g.save_fig('example.pdf').
For the second option, expGraph has options to set filepath and filename, please see the documentation.
Best,
Chao |
