Hi airflow,
We will add to Origin 7.5 SR2 a couple of utility functions (add_plots_to_layer(), make_plots_tree(), get_plot_type_info() from the code below) to facilitate adding plots to graph layers. For now you can use the code below.
"Your" function (the one that uses those utility functions to create plots) is make_XYXY(). You can call it directly from LabTalk window by passing arguments. As an example I provide (at the bottom of the code below), a little function test_XYXY() that calls make_XYXY().
