XY chart, interval painting related to Y-axel values

[pappa]

Hi, I need to implement block painting related to Y-values for my project something similar than in picture below.


I am new to JFreeChart and I would appreciate if someone could point to me which classes to use/override for achieving this.


Thanks in advance

A suitable Marker might work for the color ranges, and a suitable Annotation might work for the images.

Thanks, I'll look into those.
