graphes! help!

[Khurom Kiyani]

Hi guys, I just started using lyx about three monthes ago. Intermittingly wrting up my final year report. I'm having trouble getting graphes from excel into, into lyx. i'm using thw indows version. I have been writing the graphs onto file via a postscript driver , but when i try to scale the picture down or even just stickiing it in with its normal a4 size, it just won't show on the dvi or postscrpt preview and it does'nt print either. Any tips? Thanks Khurom
