Class Summary
Heatmap Static image rendering for heatmap visualization of spatial HDFS activity patterns for scalable rendering on front-end (web-browser) Handles database data retrieval, transforming data to form for visualization elements, and initializing and calling visualization elements
Heatmap.HeatmapData Internal representation of all data needed to render heatmap; data-handling code populates this data structure
Swimlanes Static image generation for Swimlanes visualization for scalable rendering on front-end client (web-browser) Handles database data retrieval, transforming data to form for visualization elements, and initializing and calling visualization elements
Swimlanes.CoordScaler Provides convenient rescaling of raw values to be plotted to actual pixels for plotting on image
Swimlanes.SwimlanesStateAction Prefuse action for plotting a line for each state
Swimlanes.SwimlanesStatePalette Provide constant mapping between state names and colours so that even if particular states are missing, the colours are fixed for each state
