Merge fields

Optionally merge more keys, so we convert a multiple dimensional table into a two dimensional table which can be visualised by x y graph.

Example 1

In this example dataset:

Size Year Green Blue
Small 2010 10 15
Small 2015 12 17
Medium 2010 30 35
Medium 2015 32 37
Large 2010 60 70
Large 2015 62 72

If you merge the Year field with keys(Green, Blue), you would get a table that looks like below. In this way it can be shown as a x y graph:

Size 2010 Green 2010 Blue 2015 Green 2015 Blue
Small 10 15 12 17
Medium 30 35 32 37
Large 60 70 62 72

Example 2

Another example dataset shows merge more fields:

Size Gender Year Qty
Small Men 2010 2
Small Men 2015 3
Small Women 2010 4
Small Women 2015 3
Medium Men 2010 4
Medium Men 2015 5
Medium Women 2010 7
Medium Women 2015 6
Large Men 2010 7
Large Men 2015 3
Large Women 2010 0
Large Women 2015 9

If you merge the Year field with keys(Green, Blue), you would get a table that looks like below. In this way it can be shown as a chart:

Size Men 2010 Qty Men 2015 Qty Women 2010 Qty Women 2015 Qty
Small 2 3 4 3
Medium 4 5 7 6
Large 7 3 0 9
