Hi all,
I was wondering if there is the possibility to auto define the camera
position and/or orientation in order to show the entire plotted widget when
the widget is showed, so in order words a *fit* command.
For example the attached .py file plot some random point, but when the
widget is shown you have to zoom back to view all the points.
Thanks
