  1. tooltip: {label:formatter:{@[c]}

Did you put label inside tooltip by mistake? There is no tooltip.label definition in documentation.

should show the data value of the dimension named c

A label (not tooltip) formatter for "dimension named c" should be {@c}, not {@[c]}. Square brackets are for data indexes.
