How to create a polynomial trendline in javascript?
Posted: Mon May 15, 2017 8:51 am
Hi
Is it possible to call the teechart functions in Javascript - I've read Tutorial 7 which shows it for Java but I'can't work out how to do this in javascript. I'm looking to do something like this but I can't get it to work:
Please help. Thank you.

Code: Select all
function draw() {
Chart1=new Tee.Chart("canvas");
[b] var p = new Tee.Line();
p.data.values = [5, 7, 9];
p.data.x = [0.23, 14, 16];
Chart1.addSeries(p);
polyFitting1 = new Steema.TeeChart.Functions.PolyFitting;
fastLine1 As New Steema.TeeChart.Styles.FastLine;
fastLine1.DataSource = series;
fastLine1.VertAxis = series.VertAxis;
polyFitting1.PolyDegree = 3;
fastLine1.Function = polyFitting1;
fastLine1.ShowInLegend = True;
Chart1.Series.Add(fastLine1);
[/b]
Chart1.axes.left.title.text="Y";
Chart1.series.items[0].marks.drawEvery=120;
Chart1.title.text="TeeChart for JavaScript";
Chart1.title.format.font.style="18px Verdana";
Chart1.title.format.font.gradient.visible=true;
Chart1.draw();
}
