Cant understan these bjt transistor graphs

Some desktop image capture programs don't register the contents of video players. For that you need a video editor. But in any case, there isn't that many BJT transistor graphs.

Were you referring to something like this:

Graph of collector current against collector-to-emitter voltage for a BJT, with curves labelled base currents 5, 20, 40, 50, 60 and 75 µA and a load line running from the V_supply point on the horizontal axis to the vertical axis.
