    Default JFreeChart -- TimeSeries and CandleSticks

    hello, i need a time series chart (so that when i zoom it, all charts are zoomed in and are at the correct date).

    problem is, how do i draw the candlestick chart and the other charts under a combined plot like how one would combined many XYPlots in CombinedDomainXYPlot?

    thanks.

    In connection with time series I have one more question.

    Im writing an application that uses the JFreeChart libraries and I would like to have on one screen 9 real time graphs that should be updated every 15 or 20 ms.

    Am I able to do this with JFreeChart? Will it work ?(In this case Im interested in the performance of the computer if it won´t be very consuming for system).

    It doesnt have to be written using JFreeChart. If anybody knows another API that would be better for this task I would definitely use it.
    Im asking because I have done some code but the speed is really low and the application is almost unusable.

    If it is possible I can post the code here.

    Thanks for answers :)

    You shouldn't hijack/revive an ancient and unrelated thread to ask a new question.

    The best way of getting an answer is to write some code and see.

    I'm wondering about the update rate: this computer's monitor reports a 60Hz refresh rate, so updates at 15ms (67Hz) wouldn't be visible. And. if possible, they wouldn't be discernable to a human viewer I would have thought.
