Readonly propsStatic Optional contextIf set, this.context will be set at runtime to the current value of the given Context.
Usage:
type MyContext = number
const Ctx = React.createContext<MyContext>(0)
class Foo extends React.Component {
static contextType = Ctx
context!: React.ContextType<typeof Ctx>
render () {
return <>My context's value: {this.context}</>;
}
}
The DateTime format string to apply. Some common DateTime format strings are: yyyy, MM/dd/yy, and hh:mm:ss.
The Format property provide the DateTime format string to apply.
let labelFormat = new TimeAxisLabelFormat();
labelFormat.format = "hh:mm:ss";
labelFormat.range = 1000;
this.xAxis.labelFormats.add(labelFormat);
labelFormat = new TimeAxisLabelFormat();
labelFormat.format = "hh:mm";
labelFormat.range = 60 * 1000;
this.xAxis.labelFormats.add(labelFormat);
labelFormat = new TimeAxisLabelFormat();
labelFormat.format = "MMM-dd-yy";
labelFormat.range = 24 * 60 * 60 * 1000;
this.xAxis.labelFormats.add(labelFormat);

Optional UNSAFE_Called immediately before mounting occurs, and before Component#render.
Avoid introducing any side-effects or subscriptions in this method.
This method will not stop working in React 17.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
16.3, use componentDidMount or the constructor instead
Optional UNSAFE_Called when the component may be receiving new props. React may call this even if props have not changed, so be sure to compare new and existing props if you only want to handle changes.
Calling Component#setState generally does not trigger this method.
This method will not stop working in React 17.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
16.3, use static getDerivedStateFromProps instead
Optional UNSAFE_Called immediately before rendering when new props or state is received. Not called for the initial render.
Note: You cannot call Component#setState here.

16.3, use getSnapshotBeforeUpdate instead
Optional componentOptional componentCalled immediately after updating occurs. Not called for the initial render.
The snapshot is only present if getSnapshotBeforeUpdate is present and returns non-null.

Optional getRuns before React applies the result of render to the document, and
returns an object to be given to componentDidUpdate. Useful for saving
things such as scroll position before render causes changes to it.
Note: the presence of getSnapshotBeforeUpdate prevents any of the deprecated lifecycle events from running.
Static _create
If using the new style context, re-declare this in your class to be the
React.ContextTypeof yourstatic contextType. Should be used with type annotation or static contextType.
