Index Value Plot

An index value plot allows data to be displayed and compared to the index point.

The example of the index value plot description has been directly taken from the examples website, “The AMO index is correlated to air temperatures and rainfall over much of the Northern Hemisphere, in particular, North America and Europe such as North Eastern Brazilian and African Sahel rainfall and North American and European summer climate.”
