fin-hypergrid-behavior-qtree
This element is a custom Polymer web component that demonstrates a more complex interface to Q/KDB+ by kx systems. In order for this to work you need to git clone and run
Stevan Apter's hypertree server. This Hypertree + Hypergrid example allows you to define an on-the-fly custom drill-down hierarchy while supporting interactive grouping, custom aggregation, and high-performance sorting in realtime. The current example demonstrates 20MM updates/second. The default aggregations available are sum, min, max, first, last, average, weighted average, and standard deviation. Press options/alt to drag-and-drop visible columns and the drill-down hierarchy.
