Click a chart to filter in React

Click a slice and the grid narrows to it

chart.on('click', …)

This lets you click a slice or bar in a chart and narrows the grid to it. It turns a chart into a filter control, so a reader drills from the picture into the exact rows behind it with one click.

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
