Cleanup constrainedlayout_guide.

anntzer · anntzer · commit 0bf554bcc28a · 2020-01-24T09:28:20.000+01:00
- Avoid repeated "More than X figures opened, too much memory" warning
  by setting :rc:figure.max_open_warning.

- Rename nodec to something slightly more explanatory, and invert the
  logic (`not nodec` is too twisted for me :)).  Avoid unnecessary
  duplication of `set_x/yticklabels("")` both inside and outside the
  function.  Also the arg to set_x/yticklabels is a list, not a string
  (even though an empty string "just happens to work"...

 normalized figure coordinates. It can happen that your axis labels or
 titles (or sometimes even ticklabels) go outside the figure area, and are thus
 clipped.
