/**
 * This is a recharts variant of `useSelector` from 'react-redux' package.
 *
 * The difference is that react-redux version will throw an Error when used outside of Redux context.
 *
 * This, recharts version, will return undefined instead.
 *
 * This is because we want to allow using our components outside the Chart wrapper,
 * and have people provide all props explicitly.
 *
 * If however they use the component inside a chart wrapper then those props become optional,
 * and we read them from Redux state instead.
 *
 * @param selector for pulling things out of Redux store; will not be called if the store is not accessible
 * @return whatever the selector returned; or undefined when outside of Redux store
