Chart position changes
 

Hi dears,
I have a sub work book in excel 2007 which I have some charts in its many
sheets. I open this particular worksheet through a hyper link from a
particular sheet of the master work book( also excel 2007). But charts
changes its position every time I open through this way. I can see when I
click the hyper link it starts slowly and opens the work book in the previous
condition and then swithes to the linked sheet. I think at this time interval
this dislocation happens. Every time I need to readjust to the original
location. What is wrong?
