chart positioning in a worksheet

another question, does anybody here knows how to position the chart in a worksheet such that it is on a fix position and size?
because i created a chart thru a macro, the charts layout is ok in my pc, but when i run it on another pc, the position and size is different...

maybe somebody here already encountered this kind of problem...

i will really aprreciate any suggestions

thanks in advance

hmmm it seems that the toolbars affects the positioning of the chart....the size has no problem, only the position....
