// PNEDING:
|
// (1) Only Internal usage at present, do not export to uses.
|
// (2) "Internal components" are generated internally during the `Global.ts#_mergeOption`.
|
// It is added since echarts 3.
|
// (3) Why keep supporting "internal component" in global model rather than
|
// make each type components manage their models themselves?
|
// Because a protential feature that reproduce a chart from a diffferent chart instance
|
// might be useful in some BI analysis scenario, where the entire state need to be
|
// retrieved from the current chart instance. So we'd bettern manage the all of the
|
// state universally.
|
// (4) Internal component always merged in "replaceMerge" approach, that is, if the existing
|
// internal components does not matched by a new option with the same id, it will be
|
// removed.
|
// (5) In `InternalOptionCreator`, only the previous component models (dependencies) can be read.
