Matplotlib, Qt, and borders

I?m new to matplotlib, and using it in conjunction with Qt as per https://matplotlib.org/gallery/user_interfaces/embedding_in_qt_sgskip.html, which works well. However, I?m struggling with borders, especially as the user resizes the window.

What it looks like is that the left, right, bottom and top parameters to subplots_adjust are in percents - is that correct? If so, is there a way to change it to pixels? As things stand, when the user adjusts the size of the window, the ?gap? between an edge of the graph and the edge of the container changes. More troubling is that as the window gets smaller, the graph labels get cut off.

Ideally I?d like to be able to say ?fit the entire graph (including axes labels) inside the parent object with x number of pixels padding on each side?. Of course there would be some minimum size you couldn?t effectively go below. Is that possible?

Israel,

You probably want to use `tight_layout` or `constrained_layout` on the
embedded figure.

Setting axes position in pixels would get messy if you have more than one
Axes in the figure and you want to handle resizing.

See
https://matplotlib.org/tutorials/advanced/transforms_tutorial.html#transformations-tutorial
for
the stacked coordinate systems that Matplotlib uses.

Tight_layout seems to overlap things in my experience, but I?ll give it another shot. Constrained_layout I?m not familiar with, so definitely something to try. Thanks.

I?ve always found pixel layout to be much cleaner than percent layouts, but then I?m used to designing web interfaces with a bunch of objects that need to play together nicely when you resize the window, so this is a significantly different application. That said, I was thinking along the lines of setting the border for the figure, not individual axis, but perhaps that?s not how it works?
