sadly I think this is impossible here, since the charts are generated automatically in an iframe with SVG formatting. the lines and axis are generated according to the rendered data, and by adding new data it will have to change the entire structure of the chart. on how many points are we talking about? in a single day there are 17280 point (one per 5 secs). assuming that it runs for an entire day without any interference. if your case is like that, I suggest do something else. maybe showing only the past hour for dynamic view, that way, you will have only 720 point at each time, which are rendered very fast, and another static chart for history.
