javascript teechart area series top border

Question

Hi guys,

I need to draw area series border only on the top. I attached what I have today.

Thanks in advance.

Answer 1

The easiest would be to hide the Area pen:

areaSeries.format.stroke.fill = 'rgba(0, 0, 0, 0)';

and use a Line series to draw the top. Ie:

var s = new Tee.Line();
Chart1.addSeries(s);
s.data = areaSeries.data;
s.format.stroke.size = 3;
