Hi,
I am not sure why your datasheer doesn't refresh. I assume you are using wizard from VFP to generate graph whic doesn't allow to regenerate graph.
Anyway, you could try to install excel into your client machine and see it works or not.
I am not the most powerful man in this world.
I am not the worst man in this world either.
I just as same as all of you.
I still need to learn from my mistakes...
