ABSTRACT
Computer sliders are a generic user input mechanism for specifying a numeric value from a range. For data visualization, the effectiveness of sliders may be increased by using the space inside the slider as
• an interactive color scale,
• a barplot for discrete data, and
• a density plot for continuous data.
The idea is to show the selected values in relation to the data and its distribution. Furthermore, the selection mechanism may be generalized using a painting metaphor to specify arbitrary, disconnected intervals while maintaining an intuitive user-interface.

Compound brushing
INFOVIS'03: Proceedings of the Ninth annual IEEE conference on Information visualizationThis paper proposes a conceptual model called compound brushing for modeling the brushing techniques used in dynamic data visualization. In this approach brushing techniques are modeled as higraphs with five types of basic entities: data, selection, ...
Quantitative data visualization with interactive KDE surfaces
SCCG '10: Proceedings of the 26th Spring Conference on Computer GraphicsKernel density estimation (KDE) is an established statistical concept for assessing the distributional characteristics of data that also has proven its usefulness for data visualization. In this work, we present several enhancements to such a KDE-based ...
