Mpl Canvas Size Example
===============================================================================
An example of how to override tolkit-supplied size hints on your widget.
The toolkit-supplied size hint for MPLCanvas is 480 x 640 pixels, which
prevents you from sizing the canvas smaller. This can be a problem when you are
presenting a large grid of Matplotlib figures.
This example demonstrates how to override the tookit-supplied size hint for
MPLCanvas. By setting resist_width, resist_height, hug_height, and hug_width to
'ignore', you can resize the figure almost freely in any direction.
This serves to demonstrate how the resist, hug and limit constraints interact
to control the size of a widget.
resist:
If "strong", the widget will not shrink smaller than the preferred size
(i.e., the constraint `width >= width_hint` or `height >= height_hint` is
set on the object).
hug:
If "strong", the widget will not change from the preferred size (i.e., the
constraint `width == width_hint` or `height == height_hint` is set on the
object).
limit:
If "strong", the widget will not expand larger than the preferred size
(i.e., the constraint `width <= width_hint` and `height <= height_hint` is
set on the object).
To allow a MPLCanvas to shrink smaller than the default size but not expand
larger:
resist = ignore or weak
hug = ignore or weak
limit = strong
To allow a MPLCanvas to expand larger than the default size but not shrink
smaller:
resist = strong
hug = ignore or weak
limit = ignore or weak
To disallow a MPLCanvas to change in size:
resist = strong, ignore or weak
hug = strong
limit = strong, ignore or weak
