Method and apparatus for providing visualization of information contained in a data set is provided. The data set is arranged in first and second categories of data, and a selection variable and a summary variable are chosen from the second category of data. A unique value is located in the first category of data which matches each selection variable, and a statistical summary of the summary variables is computed for each located unique value in the first category of data. The resultant display is based on the computation of the statistical summary.

Calculation and visualization of tabular data

A cluster interface is generated which represents similarities of semantics between segments of code with respect to both the physical constructs of the code and the underlying operations performed by the code. The generated interface represents one or more code segments. Code segments to be analyzed are received by a computer system. Statistical internal information is extracted from each code segment. An external metric is generated which is based on the extracted statistical information. An interface display is created from the external metric which represents similarity relationships between the inputted code segments based on the extracted statistical information.

Method of generating a browser interface for representing similarities

Cave plots are a graphical techniques for comparing two time series using overlapping and opposing coordinate systems. The plots are space-efficient, allowing comparisons involving many data points and can be used with irregularly-spaced time series.

Method of displaying multiple time series and display generated thereby

The present invention is predicted upon the discovery by applicants that is scattered light from an etched workpiece is measured over many orders of diffraction, important characteristics of the etched workpiece can be correlated with the principal component content of the intensity characteristic. In accordance with the present invention, an etched workpiece is inspected by 1) exposing the workpiece to a beam of coherent light, 2) measuring the intensity of the light scattered from the workpiece over a range of spatial frequencies corresponding to a plurality of diffraction orders, 3) determining the principal component content of the tested workpiece intensity envelope, and 4) accepting or rejecting the workpiece in accordance with whether or not the principal component content satisfies predetermined criteria. In preferred embodiments the principal components are determined in relation to a plurality of reference measurements by singular value decomposition.

Method for inspecting etched workpieces

Through the intentional introduction of dopants into a glass structure by utilizing a procedure such as is involved in the modified chemical vapor deposition technique and through subsequent drawing of this structure into capillary tubes, a body is formed that is useful for chromatographic processes. For example, the production of an alumina-doped tube allows selective chromatographic separation of unsaturated organic compounds.
