            getCtx().beginPath();

            if (len == 1) {
                saveInfo(getArr(), downX, downY, e.pageX, e.pageY, line);
            }
            //
            // _self.saveCtx(getCtx(), "round", "round", colorPen, colorPen, _self.settings.lineWidth, ex, ey);
            //
            if (missPen) {
                getCtx().lineWidth = 20
            }
            getCtx().lineTo(e.pageX, e.pageY);
            getCtx().stroke();
        },

reset track method:
function setNew () {

var canvastest = document.getElementById("canvasTest");
ctxtest = canvastest.getContext("2d");
// ctxtest.clearRect(0, 0, window.screen.width, window.screen.height);
canvastest.style.display = "block";
canvastest.width = 928;
canvastest.height = 406;
console.log("")
console.log(dataOld1)
for (var i = 0; i < dataOld1.length; iPP) {
    ctxtest.beginPath();
    ctxtest.moveTo(dataOld1[i].sx, dataOld1[i].sy);
    ctxtest.lineTo(dataOld1[i].ex, dataOld1[i].ey);
    ctxtest.closePath();
    ctxtest.lineJoin = "round";
    ctxtest.lineCap = "round";
    ctxtest.strokeStyle = dataOld1[i].c;
    ctxtest.lineWidth = dataOld1[i].w;
    ctxtest.stroke();
}

}

what result do you expect? What is the error message actually seen?

want to redraw the "4" of figure 1 to the first artboard in figure 2 (not the way the picture is drawn). Ask the great god for advice, thank you

I know that the sx and sy of the current point of the canvas, track should be the ex and ey, of the last point.
