+  Creates a Column Chart. Much of the methods are inherited from Bar. A Column Chart is a useful visualization technique to display quantitative information for different 
+  categories that can show some progression (or regression) in the data set.
+  As with all other series, the Column Series must be appended in the *series* Chart array configuration. See the Chart 
+  documentation for more information. A typical configuration object for the column series could be:
