/**
|
|
* "data" is the data of the chart - it has no type because this part of recharts is very flexible.
|
|
* Basically it's an array of "something" and then there's the dataKey property in various places
|
|
* that's meant to pull other things away from the data.
|
|
*
|
|
* Some charts have `data` defined on the chart root, and they will return the array through this hook.
|
|
* For example: <ComposedChart data={data} />.
|
|
*
|
|
* Other charts, such as Pie, have data defined on individual graphical elements.
|
|
* These charts will return `undefined` through this hook, and you need to read the data from children.
|
|
* For example: <PieChart><Pie data={data} />
|
|
*
|
|
* Some charts also allow setting both - data on the parent, and data on the children at the same time!
|
|
* However, this particular selector will only return the ones defined on the parent.
|
|
*
|
|
* @deprecated use one of the other selectors instead - which one, depends on how do you identify the applicable graphical items.
|
|
*
|
|
* @return data array for some charts and undefined for other
