So basically, I'm saying that obviously the thing doesn't work because you are grossly overdoing the resolution. Actually it does work. Regardless of resolution, my performance is bad because of how much data objects I am creating (as seen from my previous post). But I did do an experiment to test ...

I'm sure you're right. I haven't worked with Annotation yet, but the methods I was referring to (i.e. a setter to go with the getter) don't require subclassing or exposing the object state. They more or less seem left out. These lines in IntervalMarker: public void setStartValue(double startValue){ ...

plot.setBackgroundImage(Image)???

Is there something wrong with this method?

Code: Select all

JFreeChart.setBackgoundImage()
works but,

Code: Select all

plot.setBackgroundImage()
doesn't

The image used for both methods is the same.
Just curious if this is a bug.

I have a time series chart where the range axis can be 0 to anything (Depends on the application). I have several range markers that signify specific intervals that a particular apparatus is within range of. I have a custom popup menu where ranges can be updated and where the Interval markers can be...
