Title: DOC/BUG: Fix references to demo files

**This is a work in progress**

Fixes #2766

I uncovered several other bad references to files in other docstrings:
1. fill_demo
2. hline_demo
3. hist_demo
4. errorbar_demo

I'll try to fix these too once I get to a machine that build the docs w/o running out of memory
