According to an example computer-implemented method, user input is received indicating N regions within a data range of a data variable, where N is greater than or equal to three. A slide control is displayed representing the data range and the regions within the data range. The slide control includes N−1 sliders, with each slider representing a boundary between two of the regions. Responsive to movement of a selected slider, its associated boundary is reset. A determination is made of which one of the regions within the data range a received data variable value falls within. Based on the determination and the boundaries, the following items are displayed separately from the slide control: a graph of the data range that indicates which region the received data variable falls within, and a percentage value that indicates where the received data variable value falls within the data range.
