Patent ID: 10217255

Abstract:
Embodiments automatically create an axis break in a bar chart or waterfall chart to promote data visualization. For a bar chart with positive bars, a maximum axis break point is determined relative to a lowest datapoint (D1) in the selected bar(s). A minimum axis break point is found from a value (D2) outside selection which is between D1 and zero, and which is closest to D1. The inclusion of padding on either side of a break prevents the break from lying at zero or a bar end. A different procedure creates axis breaks in a waterfall chart. Certain embodiments store only bar selection metadata with a chart. The location of the axis break then is recalculated each time the chart is rendered (e.g., with updated data). Embodiments may retain axis break data for reference in various stages of a user interaction (e.g., filtering/expanding, drilling-down/up, etc.) with a rendered chart.
