Added JFreeChart as the drawing library and modified the code accordingly.
Fixed the build environment after adding JFreeChart dependency. Still need to fix javadoc error message in ANT.
Adjusted javadoc compilation.
Minor.
Added the pca folder providing different ways of computing the PCA. Missed that when integrating Piotr's code about JFreeChart etc.
Cleared a few 'unused library' cases.
Minor.
Modified the polygon style.
Enabled star shape through classes from http://java-sl.com/shapes.html.
Integrated to use length information, if provided. Default otherwise.
Integrated coverage. The transparency is the square of the normalized coverage value.
Minor.
Minor.
Fixed using int instead of float to define the Color when length, coverage, and a label are specified.
Minor changes in MainFrame.java. Set EJML to be default PCA library and modified some label names in the JFrame.
Minor. Changed the default color when no label annotation is provided.
Minor.
Removed 'A_init' from PrincipleComponentAnalysisMtj.java. The matrix A is now directly populated in the loop.
Modified PCA computation. Improved PrincipleComponentAnalysisMtj.java but ignoring the 'Y' matrix as it is not necessary if the projections of *individual* points are computed. Computing the projection of *all* points via matrix-matrix multiplication with 'V_red' entails more memory usage. PCA library Mtj is now again default.
Added JAR file w/ changes integrated (MTJ, JFreeChart, etc.).
