Hi James,

But, the ImageProcessor which is displaying the plot can be updated with a new Plot's data.

It might not be so simple for you to implement but that is the approach we took in BoneJ's Anisotropy plugin, which shows a live updating line plot with error bars and auto-scaling x axis. See createGraph() and updateGraph() here:

https://github.com/mdoube/BoneJ/blob/master/src/org/doube/bonej/Anisotropy.java#L365
https://github.com/mdoube/BoneJ/blob/master/src/org/doube/bonej/Anisotropy.java#L634

Not sure how you would do this in the macro language, however.
