    Hi,

    i have a chart with live data fetched by ajax/php. I want to show only the last x points (e.g. 50) of the series. I don´t want to have a “messed” chart after 1000 points. But it also should be possible to view the history of points (maybe horizontal scrollbar).

    Any ideas how to achive this?

    Thanks

    @mwick,

    You can achieve your requirement using viewportMaximum and viewportMinimum as shown in this JSFiddle.
