Read and set curved line and arrow format options
LabTalk Object Type:
The line4 object is a subobject of the system object. The line4 object properties allow you to read and set Curved Arrow format options stored in the SYSTEM.CNF file. These properties are set in the user interface through the Object Properties dialog box. Note that setting these properties through script will overwrite the values in SYSTEM.CNF when the Origin session terminates.
Note: Changing default arrow characteristics will affect only new objects created with the Curved Arrow tool of the user interface.
