I just can't seem to grok plotting library documentation! I have spent ages looking at the documentation for Bokeh and I can't figure out how to turn on the grid for this example: http://docs.bokeh.org/en/latest/docs/gallery/image.html This is despite the fact that the thumbnail for this example actually does show the grid as seen here: http://docs.bokeh.org/en/latest/
I have tried looking at other gallery examples which do have grids visible but alot of them make no mention of grid.
Any ideas? Thanks!
I am afraid you have uncovered a deficiency in the current version (0.8.1) of Bokeh. The Image glyph was move to the underlay render level, which is the same as the grid. If you pan the plot, you will see the grid is actually on, the image is just on top of it. This might OK sometimes, but there is unfortunately not any way to change the render level back lower if that is what is desired. I've made an issue you can track:

This will be fixed in the 0.9 release.
