在图表中的看似随机化的时间序列中显示数据?

I have a set of data in a database. In my searchings and previous attempts at such, I found jpgraph; however that isn't the best for "randomized" time-sequencing (and I don't like the layout of their gantt).

What I am looking for is a library/api/whatever for either (prefferably) PHP or (if it's awesome) javascript (prefferably jquery, but not a neccessity). Any suggestions?

Ended up using flot, PHP is too slow for what I need.
