Jfreecharts in RM

Hi,
Is it possible to use Jfreecharts in rapidminer? is there any example usage for the same

What do you mean by using them? For examples you can have a look at the plotting implementation, both the old Plot view and the new Advanced Charts use JFreeChart under the hood.

Hello,
I want to create a custom Jpanel which contains 4 scatter plots, I want to show this in real time as the learner is running. Any pointers on how to create such custom graphs? for real time updates of single scatter plot, i find there is already an example from evolutionary optimization. But I would like to create a custom Jpanel with 4 charts embedded in the same panel. Thanks in advance

First of all, real-time graphs in a separate window are against the RapidMiner design constraints - imagine you put your operator into a loop which runs a hundred times - you would end up with a hundred windows on screen. And what happens if your process runs on a headless machine? (the evolutionary optimization is just a remnant

Apart from that, you can use the JFreeChart panel just as any other java panel and use in it layouts etc. You could create 4 JFreeCharts and put them e.g. into a GridLayout with two rows and two columns.
