I am trying to create a figure of width and height of 3 inches from an existing saved figure. How can I do this?
I would like to save this figure as a .png of the same size. Can I save this as png of this (3x3 inches) size.
I have also noticed that some parts of the labels disappears when saving it to .png. Why is this so? How do I prevent this?
Many thanks,
