Brushing a time range in React

Drag a range on the chart and the grid narrows to it

brush: true

This lets you drag a range across a time chart and narrows the grid to it. It gives a reader a quick way to focus on a period, selecting the window on the chart and reading the matching rows in the grid.

Building…

Loading a live grid…

This is the React version. The grid mounts through the createLatticeGrid adapter, which takes its configuration as ordinary props and hands back the live grid through a ref. The grid below is the same one every other tab runs.

The configuration
