Performance issue with Huge amount of data

Sir,

I would like to know the performance of the JFreeChart for our requirement.

We will be having 3000 MB ~ 3 GB data in the database. From this we will be applying filter and at a time we need to plot at least 1GB data.

We would like to know how the Component performs with this much amount of data to be plotted.

Anticipating your reply.

Looking forward to hear from you.

The performance will depend on many factors, so it is difficult to predict. Do you really need to plot 1GB of data (will all the detail be visible at the resolution you draw the chart?). If you really must use 1GB of data, then you'll first need to write a class that implements the JFreeChart dataset interface *without* storing all the data in memory (unless you have lots of RAM to spare)...then I'd guess that performance will depend on how fast you can read the data (and whether or not the JFreeChart renderer you choose makes one, two or three passes through the dataset).

Try it and see, is the best advice I can give.
