I've implemented a Correlation Matrix similar to the one suggested here: Correlation matrix based on selection
I've done a duplicate/mirror table where table 1 has:
table 2 has:
Building the chart works fine - I have a pivot table with Sector and Sector1 as dimensions and it is pivoted to have Sector on the X axis and Sector1 on the Y axis.
Expression is Correl(Sales, Sales1)
Works perfectly (see screenshot below)
This works If I select a specific period of time eg
It shows over that specific period what the correlation matrix shows for my sectors.
What I'd like to do now is see what time period shows the best correlations for a particular sector.
eg the above might show correlations from 31/7/2010 to 30/6/2015 (60 months)... but maybe it turns out better for a particular sector if I run it from 1/1/2010 to 30/6/2015.
Is there any automated way of doing something like this?
