INTEGRATION OF SKETCH-BASED INTERACTION AND COMPUTER DATA ANALYSIS

Architecture that integrates the benefits of natural user interaction such as freeform sketch with computer-aided charting. The architecture integrates natural user interaction utilizing multiple modalities (e.g., sketch, multi-touch, etc.) with computer supported data analysis that allows users to explore data by drawing charts using simple strokes. Natural user interactions can be utilized to change chart types by drawing symbols, transform data by applying functions, filter data by drawing strikethrough on legends, etc. Additionally, the architecture makes an inference of visualizations the user intended from user-drawn strokes, such as the axes of a graph, the words of a label, etc. When appropriate, the architecture automatically completes visualizations.
