问：如何创建带有凸出的折线并在WebControl中对其进行填充/span>

答：示例：创建带有凸起的新折线图并对其进行阴影处理：

 var pntArray = [[0, 0, 0], [5, 5, 0], [7, 7, 0, -1], [7, 5, 0], [5, 0, 0], [0, 0, 0]];//An array of vertexes that define the polyline.Each item is an array of x,y,z,bulge.             // Bulge is the forth element of a vertex and it can be a negative number for clockwise arc or positive number for anti-clockwise arc.             var pLine = vdcanvas.AddPolyline(pntArray, true);             var ph = vdcanvas.AddPolyHatch([pLine], null, true);// add our figure in our polyhatch object             ph.HatchProperties = vdcanvas.createNewHatchProperties("u20", vdConst.colorFromString("255,255,0,255"), vdConst.colorFromString("255,0,0,255"), 1.0, 0.0);// create new hatch properties (HatchPatternName, FillBkColor, FillColor,hatchscale,  hatchangle)             ph.HatchProperties.DrawBoundary = true;//By default is false so the boundary is not be drawn             vdcanvas.UpdateFig(ph);//update the figure in order to get the changes             vdcanvas.DrawEntity(ph); // draw the figure             setTimeout(vdcanvas.redraw); // post a redraw in order to see the hatch on the canvas
