JavaScript Interface

The JavaScript Interface features a set of publicly callable JavaScript functions to retrieve the Event Stream and/or redraw the treemap according to a custom control/filter. The Event Stream is a real-time feed of all of the cell data for the currently hovered over (i.e. “active”) cell. The JavaScript Interface provides a platform for creating custom information displays, custom charts, custom treemap controls, and custom filters – which can leverage separate databases if desired.

Each JavaScript function will be described in more detail below.

  • 7.1 – Cell Data

    • getCellDataForAttr(int cell_id, string attrName)
    • getCellData(int cell_id)

  • 7.2 – Cell IDs

    • getAllCellIds()
    • getVisibleCellIds()
    • getTrackedCellIds()
    • getMouseOverCellId()

  • 7.3 – Cell Actions

    • trackVisibleCells()
    • untrackVisibleCells()

  • 7.4 – Controls Interface

    • applyControlSpec(String sXML)
    • removeFilterGroup(String filterGroup)
    • removeCelltext()

  • 7.5 – Treemap Status

    • subscribe('treemapInitialDraw', function())
    • subscribe('treemapDraw', function())
