Class Summary

Class	Description
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
