How to change the size of data coordinate tooltip?

[sprajagopal]

Hi,
I have been using jfreechart for plotting scientific data. The default tooltip that appears is way too small for convenience. Is there a way to make the data tooltip that appears at proximity to a xyseries, bigger?
I tried the following without success:
1. google a lot.
2. Use ToolTipManager.setPreferredSize
3. Search for ways to acquire the datatip as a JComponent and then setPrefferedSize on it. I couldn't find any ways to acquire the JComponent.
Thanks,
Prasanna.

ChartPanel is the JComponent that holds a reference to the shared instance of the ToolTipManager, but setPreferredSize() won't change the size of the toptip text. You could try changing the font or using HTML.
