Visualization in Chameleon Statistics

At Seventh Sense Software we know that presentation matters and we appreciate the importance of fine visualization. No matter how good the underlying mathematics may be, poor presentation of data or results can mean the difference between success and failure for a research project or business opportunity.

And that is why we have worked so hard to make sure that the Chameleon Statistics suite offers some of the finest statistical visualization techniques available anywhere. Below we give just a small sample of the kinds of visualization provided.

The scatter plot view provides one, two or three-dimensional representations of any multivariate data set. All scatterplot images can be rotated in two or three dimensions in real time, even as you work on the data. The scatter plot view is highly configurable, from the choice of visualization scheme to the selection of colors and symbols for classes to the font settings for sample labels. The 3D orientation of the axes, the position of origin, and the scale are all freely adjustable.

The binary tree view displays the dendrogram resulting from hierarchical clustering. The dendrogram is also fully configurable, viewable horizontally and vertically in city block or pyramidal schemes and in a wide range of styles. Both clusters and subclusters of clusters may be defined and colored as desired. The dendrogram can be traversed and manipulated easily using the mouse and cursor keys. Both log scale and linear scale are supported for merging heights.

The profile view provides a clear and intuitive summary of the statistics of the data samples. For each variable, the mean, range, standard deviation, quartiles and overall distribution of values are displayed. The statistics for a single variable or for all variables simultaneously can be displayed using any of several predefined or user-defined styles.

The image view allows the display of any kind of image data set, such as multispectral remote sensing imagery, or simple scanned photographs. Support for (uncompressed) bitmaps is also included. Bands can be individually selected for display in RGB or grayscale. Clusters may be overlayed onto the image for interactive manipulation.

Chameleon Statistic's unique and proprietary graphical techniques for visualization of density estimates and their contours not only make for stunning presentations which place our software light years ahead of the competition, but also promise to set new paradigms in statistical data representation. We think you will agree!
