how I can read the error rate generated with Error Plot -RProp LMP leaner

how I can read the error rate generated with Error Plot -RProp LMP leaner?? 
I used the zoom but the value is still high? I used as maximum number of iterations 500

 

Thanks

Unfortunately, that's currently not possible. I am happy to track this as a feature request and I agree it makes sense to provide the final error rate as flow variable at the node outport.
