hFE value (a.k.a β or gain factor) for transistor, at different voltage

I've been looking into the BC337 NPN transistor, and I saw in the hFE graph on page 3 of the datasheet, that the graph was at 1 V from the collector to emitter. Is there any way to find out the hFE value for a different voltage like 5 or 10 V? I've looked for a datasheet with a different voltage but have been unsuccessful.
