Using Microsoft Excel 2010, if have a range (in my case, a name defined as OFFSET(A!$A$10,0,1,1,B!$J$4)) that I’m using as chart series values, how can I apply a function to transform this range, multiplying each element by -1?
I would like to “flip” the range’s values on my chart without having to manually write out a table to transform the values one by one:

The ultimate goal is to display the red series in the positive area, along with the blue and green series, even though the red series data is negative. I would like to do this in the most simple way possible, preferably by simply applying a function to the range.
Make your named range
