The JfreeChart nodes plot data like the other Data Views nodes, but:
- the JFreeChart nodes export a non-interactive image and not an interactive plot
- the JFreeChart nodes have a configuration window used to save the plot settings
- the quality of the image is usually nicer in the JFreeChart nodes than in the Data Views nodes.
Below we compare a histogram generated with a JFreeChart node (image) and a histogram generated with a Data Views node (interactive plot).
In conclusion, if you need an image, to export for example in a report, and do not need to interact with your plot, then the JFreeChart nodes are what you need.
On the opposite, if you are just in an exploratory phase of your investigation and you want to visually check your data, then you need to work with the Data Views plots.
