canvas.strokePoly

    canvas.strokePoly(xarray, yarray, color)
//OR
    canvas.strokePoly(xyarray, color)

Stroke a polygon through the points defined in xytable with a specific color. The width of the line is the last value passed to canvas.setLineWidth or 1 if no width has ever been specified.

Parameters

Parameter	Type	Description
xarray	number[]	An array of x values.
yarray	number[]	An array of y values.
color	number	An RGB color value as an integer value.

OR

Parameter	Type	Description
xyarray	{x: number, y: number}[]	An array of objects that each contain an x and y variable such as [{x:x1,y:y1},{x:x2,y:y2}...].  Used instead of the xarray and yarray.
color	number	An RGB color value as an integer value.

Example

    // Stroke a triangle using a polygon
    function StrokeRedTrianglePoly(name) {   
        var canvas = sb.getCanvas(name);   
        var mid = canvas.width / 2;   

        //Shrink the bounds to make the lines visible   
        var height = canvas.height - 2;   
        var width = canvas.width - 2;   
        const pts = [];   
        pts[0] = {x:2,y:2};   
        pts[1] = {x:mid,y :height};   
        pts[2] = {x:width,y:2};   
        pts[3] = pts[0];  //Close the polygon   
        canvas.strokePoly(pts, 0xff0000)
    }
