What is the problem?
I would like to ask if graph operation can be handled in octopi. That is, if some functions, such as drawing a graph, display a picture and so on, can be supported by octopi? If yes, may I ask there are any plugins that can be installed in octopi to implement these operations?
What did you already try to solve it?
I install octopi on raspberry pi 3B to control a chocolate 3D printer. What I want to do next is to develop a function that stick figure drawn by user can be directly sliced by CuraEngine and printed by the printer. Moreover, some graphic models can be displayed on front interface. Octopi is light version of raspbian. So I am not sure if octopi can support these functions?
The version of the octopi I used is Raspbian GNU/Linux 9
