Subject: [PATCH 6/8] doc: Modify examples to _really_ be non-default.

The axes props demo is trying to set the grid style to something
non-default, but the default is now solid, so it appears to do nothing.
Similarly, the "thick" lines in the axhspan don't appear so thick any
more now that the default line style is a little thicker.

Otherwise, without the edge lines, it's just a couple of error bars in
the middle of the longer bar.
