1. An apparatus to retrieve data from a relational database, wherein the data includes one or more database dimensions, one or more database dimension values and one or more function values, and wherein the one or more database dimensions are database groups into which the data are organized, the one or more database dimension values are elements of which a respective database dimension is composed, and the one or more function values are related to a measure of a respective database dimension, the apparatus comprising: a display device; and a processor to execute program code to cause the apparatus to: present, using the display device, a visualization indicating a first plurality of database dimension values and a respective function value for each of the first plurality of database dimension values, the function values positioned in accordance with an initial scale of a function value axis, and the first plurality of database dimension values positioned in accordance with an initial scale of a database dimension value axis; detect initiation of an input gesture to change the visualization of the indicated first plurality of database dimension values by at least one of adding a first one or more database dimension values to the visualization by displaying the added first one or more database dimension values along the database dimension value axis and removing a second one or more database dimension values from the visualization by removing the second one or more database dimension values from the database dimension value axis, wherein the added database dimension value is not one of the first plurality of database dimension values; before completion of the input gesture, determine a second plurality of database dimension values to indicate in the visualization based on the input gesture; before completion of the input gesture, determine an updated scale of the function value axis based on the respective function values for each database dimension value of the second plurality of database dimension values; and before completion of the input gesture, display the respective function values for each database dimension value of the second plurality of database dimension values positioned in accordance with the updated scale.
