Spiral Theme Plot

چکیده
We introduce a new visualization method for temporal data, Spiral Theme Plot, by combining ThemeRiver method, spiral patterns, and scatter plot technique. Similar to ThemeRiver, data in different categories (themes) are visualized in different bands, but also in a spiral pattern. Themes are stacked along a spiral curve, which represent the time axis. Individual data points are plotted within the regions of the themes, with various visual features. In addition to showing the overall theme patterns over time, this approach also shows plotting patterns within the themes. Compared to ThemeRiver, Spiral Theme Plot can accommodate longer time axis, and more importantly, can provide periodic patterns that are typically not available in ThemeRiver.

Graphing One Dimensional Numeric Data
A strip plot graphs one dimensional data by displaying each sample point as a point on a one dimensional axis. The main difficulties with this technique is (i) when several samples have identical values they will be printed on top of each other, and (ii) in the case of a large sample the graph will become overly crowded and less informative. The two ways to alleviate these difficulties are: (a)...
متن کاملStructural Characterization of Polymers by MALDI Spiral-TOF Mass Spectrometry Combined with Kendrick Mass Defect Analysis
High-resolution mass spectrometry (HRMS) continues to play an important role in the compositional characterization of larger organic molecules. In the field of polymer characterization, however, the application of HRMS has made only slow progress because of lower compatibility between matrix-assisted laser desorption/ionization (MALDI) and ultrahigh-resolution Fourier transform ion cyclotron re...

We report simultaneous H110α and H 2 CO line observations with the NRAO Green Bank Telescope toward 72 H II regions in the SPITZER/GLIMPSE survey area (|l| = 10 • − 65 • and |b| ≤ 1 •). We used the H110α line to establish the velocity of the H II regions and H 2 CO absorption lines to distinguish between near and far distances. Accurate distances are crucial for the determination of physical pr...
متن کاملGas Dynamics in the Milky Way: Second Pattern Speed and Large–Scale Morphology
We present new gas flow models for the Milky Way inside the solar circle. We use SPH simulations in gravitational potentials determined from the NIR luminosity distribution of the bulge and disk, assuming constant NIR mass-to-light ratio, with an outer halo added in some cases. The luminosity models are based on the COBE/DIRBE maps and on clump giant star counts in several bulge fields, and inc...
متن کاملMarking Theme and Rheme in Preverbal Messages *
Combinatory Categorial Grammar (Steedman, 2000, 2006) shows that certain intonational patterns in English mark an utterance’s theme and rheme (L+H* and H*, respectively). The incremental conceptualiser (inC) can be extended to produce preverbal messages (semantic representations) containing the required marking of theme and rheme for pointing out a mismatch between the maps in the Map Task. Thi...
