    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 wont 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.
