Get max/min values from WING graphic via API

HI, is it possible to get maximum (or minimum) value which is displayed in wingraf graphic/picture/layer via Python API? I have often use box option of wingraf to show design state, but I have no idea how to get this value in Python. Best regards

Wingraf calculates the max/min values on the fly and doesn’t store them in the database.
If you want the max/min value for a set of elements (=view), you have to loop through them and check yourself.
