JavaScript/jQuery Chart - Access a Series Using the API
The Chart exposes the following methods for accessing a series. All of them return one or several objects whose fields and methods are described in the Series section of the API reference.
getAllSeries()
Gets all series of the Chart.JavaScript- var seriesCollection = $("#chartContainer").dxChart("getAllSeries");
getSeriesByName(seriesName)
Gets a series by its name.JavaScript- var series = $("#chartContainer").dxChart("getSeriesByName", "Series 1");
getSeriesByPos(seriesIndex)
Gets a series by its index in the series array. The index is zero-based.JavaScript- var series = $("#chartContainer").dxChart("getSeriesByPos", 0);
Apart from the API methods, you can access a series in the event handlers. For example, the onSeriesClick event handler gets the clicked series in the argument.
- $(function() {
- $("#chartContainer").dxChart({
- // ...
- onSeriesClick: function (e) {
- var series = e.target;
- // ...
- }
- });
- });
Once you get the series, you can access its child points. For further information, refer to the Access a Series Point Using the API topic.
