React component for the wijmo.chart.finance.analytics.ATR class.
The flex-chart-atr component should be contained in a wijmo.react.chart.finance.FinancialChart component.
The component includes an initialized event that is raised when the control is initialized after it is added to the page. You can use this event to perform further initialization in addition to setting properties in JSX. The signature of the handler function is the same as any other Wijmo event handlers.
