Grapheme is a data analysis, visualization and statistics package software developed at iChrome Ltd.
History
Grapheme is developed and distributed by iChrome Ltd, a privately owned company headquartered in Bristol, United Kingdom. Grapheme was originally developed as a Java-based general purposes charting library at iChrome Ltd to be used as Eclipse RCP plugin within iChrome's products. Later on, in 2015, Grapheme was evolved into a stand-alone and self-contained software for data flow, interactive visualization and statistical analysis[1].
Modules and Capabilities
Grapheme is a data visualization and analysis tool. Grapheme is organized in three main modules:
- Data Flow and Database Connectors
- Charting and Interactive Data Visualization
- Statistical Analysis and Regression
Data Flow and Database Connectors
This module allows importing and connecting data from external software and sources. Users can define data analysis chains to manipulate and stream large sets of data from raw sources into aggregated meaningful sets of information either via scripting or visually via the Graphical User Interface.
The data flow module provides data operations such as:
- Expressions to combine existing results into new outputs;
- Filters to filter out specific subsets of values. Among those operations:
- Pareto filter;
- Percentile and range based filters;
- validity filters, i.e. filters to exclude NAN, empty or invalid values;
- Join and Aggregation to join and aggregate results via user-defined matching rules, i.e. indexing
Charting and Interactive Visualization
Grapheme links the imported data to charts, providing internal indexing, so that changes in data sources and data-table within the project are propagated to the user-defined charts and visualization panels. The charting library of Grapheme is based on series that can be combined into multiple chart templates. Grapheme provides:
- 2D cartesian charts:
- line scatters, clustering, regressions and bubble charts
- 3D cartesian charts:
- surface and wireframe plots, 4 and 5 dimensional bubble charts
- Category based-charts
- bars, pies, candle-stick
- multi-axis charts
- parallel coordinates and radial charts
Statistical Analysis and Regression
This module uses the data made available within a project to perform statistical analysis. Results are organized in panels to display meaningful results both via ad-hoc charts and in tabulated format.
Wizards guide the users in setting up the analyses. Grapheme version 2.5 groups the analyses panels as follows:
- Statistical Analysis:
- Descriptive Statistic, Correlation, Covariance analysis
- ANOVA (one and two ways)
- MANOVA (one and two ways) and General MANOVA
- Principal Component Analysis
- T-Tests, Normality
- Regression Analysis:
- Single Predictor fitting
- Multiple Predictors non-linear and polynomial fitting
- Control Panels:
- Symmetry chart analysis
- Multi-Vari chart analysis
- Pareto Chart analysis
- Interval Chart analysis
- Quality (Six-Sigma) and Process analysis:
- Attribute Agreement Analysis
- Capability (Normal) Analysis
- Gage Linearity and Bias Analysis
- Process Control Analysis
