You can certainly graph a reverse Y-axis, and you can use AJAX to push data back to your server (the Visualization API won't do this for you, but it is easy enough to write AJAX functions using other libraries [jQuery, MooTools, etc]).
Adding points to a chart based on the user clicking is a bit trickier, but also doable. One of the dev team put together a demonstration for this a few months back: http://jsfiddle.net/8Fsf4/ On Tuesday, January 21, 2014 2:28:26 PM UTC-5, cjm287 wrote: > > Have been searching for a long time no try to find a clickable chart that > does what I want. > > I really need to do two things. > > 1.
