Polychromatic plots: Graphical display of multidimensional data

Graphical display of fMRI data: visualizing multidimensional space.

Visualization of multidimensional data is an integral part of computational statistics and exploratory data analysis (EDA). We show how visualization of fMRI time-courses may be used to reveal the fMRI data structure. We consider fMRI time-courses (TCs) as points in multidimensional space. In simulated and in vivo data, we show that minimum spanning tree (MST)-based sequencing of multivariate t...

The Use of Color in Multidimensional Graphical Information Display

The performance in judging values in a univariate map encoded using five different color scales was tested in eleven subjects. Digital elevation maps (DEMs) were encoded using: 1) an RGB gray scale (RGB), 2) a gray scale based on CIELAB L* (L*), 3) a L* scale with an added red hue component (Red L*), 4) an L* scale with continuous hue change (Spectral L*), and 5) a gray scale based on luminance...

Graphical Display System

CARDIAC ULTRASOUND has greatly enhanced our ability to define structural disorders in the heart and great vessels. While certain cardiac diseases lend themselves to firm diagnosis by M-mode echocardiography, many valvular and congenital disorders result in normal or nonspecific echocardiographic findings. In these disorders structural abnormalities clearly exist which cannot be evaluated with p...

Identification and visualization of multidimensional antigen‐specific T‐cell populations in polychromatic cytometry data

An important aspect of immune monitoring for vaccine development, clinical trials, and research is the detection, measurement, and comparison of antigen-specific T-cells from subject samples under different conditions. Antigen-specific T-cells compose a very small fraction of total T-cells. Developments in cytometry technology over the past five years have enabled the measurement of single-cell...
