When activating the plot plugin in a jenkins job configuration
and adding 2 or more "data series files" and saving this job configuration
and then going back into the config page, only the last "data series file"
radioblock field will be shown correctly, all the others will not show
the input fields on the selected radio buttons...

This bug appears whenever you use radioblocks inside a repeatable structure.

Jenkins 1.411 + Plot Plugin 1.5 work well and don't show this bug.
Jenkins 1.464 + Plot Plugin 1.5 do show this bug.
