I'm currently working on a financial alerts application , and for the client interface I've decided to use JFreeChart. However as I'm new to it ,there are some important things that I can't figure about the ohlc charts :
-I'd like to be able to put in a chart only a limited number of bars (let's say 300) and after this number is reached the oldest bars to slide out of the chart .
-I've noticed that if for a period of time there are no bars , the domain axe still advances. For example ,if the begining time is 12:00 and I have a bar for an hour , the first bar will be for 12:00-13:00 , the next will be for 13:00-14:00, but if the next update that I get is at 17:38 then the next bar should be for the 17:00-18:00 interval . I'd like to know how to put the 17:00-18:00 bar next to the 13:00-14:00 bar without the x to advance for the 4 hours between.
-Is it possible to write my own mouse events for this kind of chart ?
Any suggestion or reference is welcomed !
