Some visualizations (ultimate-column-chart, ultimate-dual-column-chart) does not work with some aggregation

Ultimates packages do not display data for certain aggregations over data. Problem is that strings are passed instead of numbers and if it has one value for one key, then that value does not convert to float because the aggregation function that converts a string to float does not called. The same issue (ZEPPELIN-3224) closed but PR declined.
