I have a stock feed coming at an interval of every 5-10 seconds (not fixed) from the Stock Exchange. This feed contains data like "Last Trade Time", "Last Trade Price", "Volume of Transactions" etc for each scrip.
From this I have to plot two graphs for each scrip---
1. A "Time Series Chart" with the "Last Trade Time" along x-axis and "Last Trade Price" along y-axis. The Time Series Chart uses XYDataset.
2. A "Vertical Bar Chart" with the "Volume".
The conditions are:
1. The two graphs should be one below the other (I am not sure whether it should be called combined/overlaid plot).
2. Since all three parameters come at the same time in one single feed, I want that the new values in both the Time Series Chart and the Vertical Bar Chart be plotted at the same instant from the data that has come in.
I have been able to do the dynamic Time Series Chart without the Vertical Bar Chart without any problems.
The questions that I have are:
1. Is it possible to implement what I have in mind?
2. If yes, then whether I should go in for a combined or a overlaid plot or what?
3. Whether I should go in for a CategoryDataset or an IntervalDataset for the Vertical Bar Chart?
4. I have to draw the vertical bars of only one scrip with the values as and when they arrive. So, how many categories should I have, in case I have to go in for a CategoryDataset?
P.S.---David, if u're reading this, plz rply since u didn't reply when I mailed u. Anyway, I solved that problem I had mentioned in the mail
