DJIA -FTSE Differential

[spock]

Could someone please tell me the quickest way to get a graph of the difference between the Dow and the FTSE over the last ,say, one year.I can only find charts of the two indices plotted on the same graph rather than the difference between them being plotted.
Many thanks

I think you'll have to do it the hard way! Import into excel the EOD data for both chartsm and then do the calcs and chart yourself.
