FastLineSeries<T, D> class

Renders the FastLineSeries.

FastLineSeries is a line chart, but it loads faster than LineSeries.

You can use this when there are large number of points to be loaded in a chart. To render a fast line chart, create an instance of FastLineSeries, and add it to the series collection property of SfCartesianChart.

The following properties are used to customize the appearance of fast line segment:

  • color - Changes the color of the line.
  • opacity - Controls the transparency of the chart series.
  • width - Changes the stroke width of the line.
