A first chart and a second chart are parsed to determine one or more measures, dimensions, and filters visualized in the first chart and the second chart. The number of measures, dimensions, and filters visualized in the first chart and the second chart are calculated. It is determined how many of the number of measures, dimensions, and filters visualized in the first chart and the second chart are the same. One or more merge rules corresponding to the number of measures, dimensions, and filters visualized in the first chart and to the number of measures, dimensions, and filters visualized in the second chart that aren't the same as measures, dimensions, and filters visualized in the first chart are obtained, and one or more merge permutations are derived based on the obtained merge rules. The first chart and the second chart are merged in accordance with one of the merge permutations.
