# lang.accessibility.announceNewData

Default announcement for new data in charts. If addPoint or addSeries is used, and only one series/point is added, the `newPointAnnounce` and `newSeriesAnnounce` strings are used. The `...Single` versions will be used if there is only one chart on the page, and the `...Multiple` versions will be used if there are multiple charts on the page. For all other new data events, the `newDataAnnounce` string will be used.
