Hi Tyron,
we are removing Highcharts in 3.5.x; the plan is to finish for 3.5.2,
keeping the same feature set as 3.5.1, although I seem to be alone in
this adventure.

Currently, our best bet is jqplot. Have a look at this tree to see what
I've done so far, for
- query profiling
- zoom search
https://github.com/lem9/phpmyadmin/commits/QA_3_5-jqplot

As I said on this list, the jqplot author said that we can do real-time
plotting, but without the sliding animation. I guess we'll have to be
content with this.
