Angular Chart Trendlines
In Ignite UI for Angular charts, trendlines help in identifying a trend or finding patterns in data. Trendlines are always rendered in front of data points bound to the chart and are supported by the
IgxDataChartComponent (except for stacked series, shape series, and range series).
Trendlines are off by default, but you can enable them by setting the
trendLineType property. Also, you can modify multiple appearance properties of trendlines such as its brush, period, and thickness.
The trendlines also have the ability to have a dash array applied to them once enabled. This is done by setting the
TrendLineDashArray property to an array of numbers. The numeric array describes the length of the dashes of the trendline.
Angular Chart Trendlines Example
The following sample depicts a
IgxFinancialChartComponent showing the stock trend of Microsoft between 2013 and 2017 with a
QuinticFit trendline initially applied. There is a drop-down that will allow you to change the type of trendline that is applied, and all possible trendline types are listed within that drop-down.
