I have a Jfreechart which is plotting some mock real-time data. When I have my domain axis set to auto, the data can be seen updating every second. However, I wish to plot the data over a wider range (say the whole day). When I change the range, I am then unable to see the plot unless I zoom in.
Once zoomed in, the line does not cover the whole graph, but only a portion. This line then moves across the graph instead of growing/drawing along it

How do I make it so that the line is continuous (shows every observed point of data in the series), and how do I make it visible when I manually set the range
