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 |
