A tool for analyzing a sequence of data in an object-oriented environment is disclosed. In an embodiment, the sequence of data may include time-indexed sequence of data ('time series data'). The tool may provide graphical user interfaces that enable a user to analyze the time series data encapsulated in a time series object or time series collection object. The graphical user interfaces may enable a user to create a time series object and manipulate the data in the time series object or time series collection object. The graphical user interfaces may also display the data in the time series object or time series collection object in various types of plots, such as time plots, spectral plots, x-y plots, correlation plots and histograms.

Graphical user interface for analysis of a sequence of data in object-oriented environment

A tool for analyzing a sequence of data in an object-oriented environment is disclosed. In an embodiment, the sequence of data may include time-indexed sequence of data ('time series data'). The tool may enable a user to generate a time series object for encapsulating the time series data in the object-oriented environment. The user may construct the time series object from data or mathematical expressions using a command line interface. The time series object may include a sequence of objects implementing APIs that supply an interface for analyzing the times series data in the time series object. The user may analyze the time series data encapsulated in the time series object using the APIs of the time series object.

Analysis of a sequence of data in object-oriented environments

A method for forecasting batch end conditions through their depiction as a multi-dimensional regions of uncertainty is disclosed. A visualization of the current condition of a continuous process and visualization of the simulated effect of user control moves are generated for a user. Volume visualization tools for viewing and querying intersecting solids in 3-dimensional space are utilized to perform the process visualization. Interactive tools for slicing multi-dimensional (&#x3e;3) regions and drawing superimposed projections in 3-D space are provided. Additionally, graphical manipulation of the views of process conditions is accomplished by changing the hypothetical future values of contributing variables online in order to provide users the ability to simulate the effect of proposed control actions. The illustrative embodiment of the present invention may also be utilized in combination with a graphical programming environment supporting the execution and simulation of block diagrams and correspondingly generated process data. The scores representing the process condition may depend on estimated physical quantities as well as representations of process variability.
