Perspective plots, three-dimensional

An HH COSY diagram can be shown in perspective as a stacked plot (Fig. 2.10a). Interpretation of this neat, three-dimensional representation, where the signal intensity gives the third dimension, can prove difficult because of distortions in the perspective. The contour plot can be interpreted more easily. This shows the signal intensity at various cross-sections (contour plots, Fig. 2.10b). However the choice of the plane of the cross-section affects the information provided by an HH COSY diagram if the plane of the cross-section is too high then the cross signals which are weak...

Three-dimensional perspective plots which show the relationships between tt, types examined. Herbicidal activity differences induced by surfactant addition to TFMS formulations are demonstrated by these plots.

Figure 47.5 is a two-dimensional (2D) bubble plot that illustrates another perspective of examining the relationship between the predictor variables and biomarker response. In essence, the hgure is a 2D representation of three-dimensional data. The baseline biomarker values are on the y-axis, C ax is on the x-axis, and... 

With modern computing power it is also possible to display data as isoabsorbance contours plotted in the wavelength time plane. Peak detection is also enhanced by full-screen three-dimensional displays which can be rotated to give different perspectives aiding the location of hidden peaks. 

In addition to the two-dimensional profile of lighted fibers, this pattern (and all other image patterns) can also be displayed in the form of a three-dimensional contour plot. This interactive graph may be viewed from a variety of viewpoints in that the user can vary the elevation, rotation, size, and perspective controls.

Fig. 1. Three-dimensional perspective plot of the adiabatic potential energy surfaces of the double-sheeted ground electronic state of H3 in the (R,r) plane for 7 = tt/2, corresponding to the C 2v arrangements of the three nuclei. The contour line diagram is included in the base of the plot. The spacing between the successive contour lines is 0.3 eV. The potential energies are obtained from the DMBE PES and the lower (y ) and the upper (V ) adiabatic sheets are shown by the thin and thick solid curves, respectively. The conical intersection of the two surfaces should not be realized as an isolated point as apparently revealed by the perspective plot, rather, it represents a seam of intersections occurring for R = which is more clearly indicated by the...

The interpretation of multidimensional spectra can be quite involved, so only a simple overview will be presented here. Two-dimensional spectra are usually represented as contour plots with two frequency axes forming the base plane (e.g., 8h-5h, 5c-5c, or 6c-Jch). and intensity depicted by curves spaced according to the steepness of the ascent these plots resemble geological survey maps. The stacked plot tilts the frequency-frequency plane, showing the peaks as vertical intensity they look like perspective drawings of mountainous terrain. Three-dimensional spectra may be portrayed as false-color (to show intensity) spots in a cube formed by three frequency axes.
