Axes and legends in React

A series per category, named by the legend

series, legend

This draws a series per category, each named by the legend, with labelled axes. It shows how the grid turns a categorical column into separate series a reader can tell apart and read off the axes.

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.
