JFreeChart will handle this easily with a time series chart. You can either copy your data into the default time series dataset implementation (TimeSeries and TimeSeriesCollection classes), or you can wrap your own data structure within a class that implements the XYDataset interface (that way you don't need to duplicate your data).
