![]() From contextual inquiries, we describe an analysis of needs which established a set of requirements for interactions on sets. Our thesis is that it is important to design interactions for the synchronous operation of multiple objects that are efficient, while fostering exploratory design. In this paper, we describe our techniques in three areas: 1) the design space of sketching methods for eliciting users' nonlinear domain knowledge 2) the underlying model that translates users' input, extracts patterns behind the selected data points, and results in nonlinear axes reflecting users' complex intent and 3) the interactive visualization for viewing, assessing, and reconstructing the newly formed, nonlinear axes.Īlthough many interactive tools allows manipulating effectively objects individually by applying principles such as direct manipulation, interaction with multiple objects have been little studied so far. Using this technique, users can draw lines over selected data points, and the system forms the axes that represent a nonlinear, weighted combination of multidimensional attributes. The proposed interaction is performed through directly sketching lines over the visualization. This technique enables users to impose their domain knowledge on a visualization by allowing interaction with data entries rather than with data attributes. To overcome these challenges, we introduce a technique to interpret a user's drawings with an interactive, nonlinear axis mapping approach called AxiSketcher. Furthermore, users' complex, high-level domain knowledge, compared to low-level attributes, posits even greater challenges. However, it is often challenging for users to express their domain knowledge in order to steer the underlying data model, especially when they have little attribute-level knowledge. Visual analytics techniques help users explore high-dimensional data. Finally, we present the results of two user studies, providing initial evidence that EMS can significantly reduce interaction time compared to WIMP-based technique and was subjectively preferred by participants. We also offer a set of design guidelines for supporting EMS. We demonstrate how the EMS technique can be designed to directly manipulate width and position in bar charts and histograms, as a means for adjustment of data grouping criteria. In response, we introduce Embedded Merge & Split (EMS), a new interaction technique for direct adjustment of data grouping criteria. Such adjustments are currently performed either programmatically or through menus and dialogues which require specific parameter adjustments over several steps. Although grouping plays a pivotal role in supporting data exploration, further adjustment and customization of auto-generated grouping criteria is non-trivial. Many popular visualization tools support automatic grouping of data (e.g., dividing up a numerical variable into bins). It is the process through which relevant information is gathered, simplified, and expressed in summary form. OS X 10.Data grouping is among the most frequently used operations in data visualization. Page Orientation - Fixed a bug that caused Page Setup to default to Portrait orientation when saved with a recent version of OmniGraffle.Bézier Lines - Fixed a bug that caused some Bézier lines to incorrectly draw to the center of the shape.Localizations and Documentation - Documentation and App Localizations have been updated to reflect recent UI changes.OmniGraffle Professional has everything included in Standard, plus features suited specifically for folks that make a living designing or working with graphics. For the pro user who’s looking for an in-depth diagramming application that’s still priced below the competition, you’ve come to the right place. OmniGraffle Professional has all of the great features in the standard version, plus a powerful toolset for advanced document creation and editing options. If you want to organize your thoughts, your projects, or even your friends graphically, using boxes and lines, OmniGraffle is your tool. We’ve had people use Graffle to plan plotlines for a story, make an overview of an operating system, show the evolution of computers, and even show how diseases can spread in a closed population. ![]() OmniGraffle Pro helps you draw beautiful diagrams, family trees, flow charts, org charts, layouts, and (mathematically speaking) any other directed or non-directed graphs.
