From the lower entryentry that is placed at the bottom of the GiD window, can invoke Tcl code writing -np- followed some space and then some tcl code an press <Return>
Note: -np- mean ‘No-Process’ (that the words are not GiD process keywords) and instead the next command is expected to be Tcl code. It is used as a fast way to run a simple procedure or re-define code.
Use copy/paste code after -np-
In particular there are some predefined Tcl procs that run python code, like GiD_Python_Exec that expects the python code to be evaluated
...
then will appear a window like this
...
Source a file with the code
-np- GiD_Python_Source $your_filename_py
...
GiD_Python_Source is a Tcl proc that expects the name of a python file with the code to be sourced
Example: matplotlib graph of two curves
The file <GiD>/scripts/tohil/doc/demo_matplotlib.py contain a code like the one of the image
