While flying OSGAR 1R star into Dublin; Ireland; we received short notice clearance to hold at BABON fix. Due to short notice; arriving from west; and having our EFBs zoomed in to read STAR info; we never saw the BABON holding pattern depicted in separate inset on extreme right side of plate. Since no hold was depicted at fix; we queried controller as to what type of pattern he wanted us to fly at BABON. He said a standard pattern; so we held on inbound course; right turns. After being vectored shortly after entering the holding; we finally saw the inset with holding pattern at BABON. It showed holding on different inbound course from different feeder fix with a left turn. It seemed no loss of separation occurred; as we were actually in the holding airspace for the most part. There is an easy fix: show depicted holding patterns at the fix on the plate. If unable due to [chart] congestion; then a ball note or something similar directing the pilot to look elsewhere would be appropriate. As nice as the EFB is; it presents a whole new set of problems. If we'd been using a paper chart; this might not have happened. Though we have been warned about this issue; the combination of having the EFB slewed/zoomed in a different direction and the short amount of time set us up for this. Also; even though we queried the controller; he was of no help whatsoever. If he had used the terminology hold as depicted; I'm sure we would have found the appropriate pattern; and this whole occurrence could have been avoided.
B757 Captain reported a track deviation on a holding pattern that was not depicted on the fix and not visible during the close-in EFB view.
