| 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.MapReduceSwimlanes |
Modifier for generic Swimlanes plots to plot shuffle, sort, and reducer
states of same reduce on same line
|
| 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
