Added a link to pretty print the page: Load the page and all the graphs with white background and without links.

In order to work, you need to define a print.yml file overriding the background and foreground colors:

graph_templates/print.yml :

:graph_properties:
 :background_color: white
 :foreground_color: black
 :vertical_mark_color: "#eeffee"

Also requires a previous patch to allow properties_include.

Improved the pretty print functionality.

Now it is not required the print.yml, it will set background_color=white and foreground_color=black.
But it can be used optionally to override other properties.

Fixed: Show only print in dashboard view.
Fixed: Not able to print time intervals.
Fixed: Not able to print detailed view.
