/**
|
|
* 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
