The best way is to copy the worksheet to a new worksheet by right clicking
the tab on the bottom of the worksheet and make a copy. Then rename the new
worksheet to abc backup or some other name.

Suppose I have a chart with, for example, data in it as follows (source data):

A1:A20

Every so often, I REWRITE over that same range new data...and create a new
chart!!

HOW CAN I SAVE MY PRE-EXISTING CHART, i.e. WITH THE OLD DATA??

Thanks,
