removeAllSeries(redraw: Boolean);
redraw. Indicates whether the chart should be redrawn. Available values:
true. The chart should be redrawn (default).
false. Chart redrawing is not required.
The removeAllSeries method removes all data series from the chart.
To execute the example, the HTML page should contains the Chart component named chart (see Example of Creating a Histogram). Remove one of the chart data series:
// Get chart series
var series = chart.getSeries();
// Show the number of chart series to the browser console
console.log("Number of chart series: " + series.length);
// Check availability of data series in the chart
if (series.length > 0) {
//Get the last data series of the chart
var serie = chart.getSerie(chart.getSeries().length - 1);
// Remove this series without redrawing the chart
chart.removeSerie(serie, false);
// Show the number of chart series after this series is removed to the browser console
console.log("Number of chart series after the series is removed: " + chart.getSeries().length);
// Redraw the chart
chart.redraw(true);
}
After executing the example the last data series is removed from the array of chart series:
The browser console displays messages on the number of chart series before and after the series is removed:
Number of chart series: 5
Number of chart series after the series is removed: 4
Remove all data series from the chart:
// Remove all data series from the chart chart.removeAllSeries();
After this a chart with no data series is displayed:
