IOComp Graph is too slow

I am asked to work in a winform which loads a graph designed by IOCOMP. The graph loads many channels like:-

IOComp.Channels.Add(chnlFlightlevel);
IOComp.Channels.Add(chnlMEA);
IOComp.Channels.Add(chnlMOCA);
IOComp.Channels.Add(chnlTROPOAUSE);

The problem is this page is too slow. On dragging scroll bars, it takes too much of time to load the portions. If I drag the horizontal scroll bar to some location, it takes a while. I tried UpdateFrameRate, BeginUpdate, EndUpdate given from this URL

Any help please?
