Hi,

Do you know how can I limit (x,y) translation of the scatter widget ?

Thank you for any help

Hi, 

You can use the on_transform_with_touch function for left, right, top and bottom limits. 

def on_transform_with_touch(self, touch):

 if self.center_x < 0:

     self.center_x = 0

 if self.center_y < 0:

     self.center_y = 0
