示例1: Draw

        public override void Draw(Android.Graphics.Canvas canvas)
        {
            base.Draw (canvas);

            Paint mBgPaints = new Paint ();
            mBgPaints.AntiAlias = true;
            mBgPaints.SetStyle (Paint.Style.Fill);
            mBgPaints.Color = Color.Blue;
            mBgPaints.StrokeWidth = 0.5f;

            Paint tPaint = new Paint ();
            tPaint.Alpha = 0;
            canvas.DrawColor (tPaint.Color);

            RectF mOvals = new RectF (40, 40, layout.MeasuredWidth - 40, layout.MeasuredHeight - 40);

            decimal total = 0;
            foreach (SecuritiesViewModel.PieChartValue value in securitiesViewModel.DataForPieChart ()) {
                total += value.amount;
            }

            if (total == 0) {
                return;
            }

            decimal degressPerAmount = 360 / total;
            decimal currentAngle = 0;
            foreach (SecuritiesViewModel.PieChartValue value in securitiesViewModel.DataForPieChart ()) {
                canvas.DrawArc (mOvals, (float)currentAngle, (float)(degressPerAmount * value.amount), true, mBgPaints);
                currentAngle += (degressPerAmount * value.amount);
                mBgPaints.SetARGB (255, new Random ().Next (256), new Random ().Next (256), new Random ().Next (256));
            }

            var radius = (Height / 2) - 4;
            var middleX = Width / 2;
            var middleY = Height / 2;

            var minutes = (int)time.TotalMinutes;

            for (int i = 0; i <= rotation; i++) {
                var angle = minutes > 60 ? 360 : (int)((minutes * 360f) / 60);

                canvas.DrawArc (new RectF (middleX - radius, middleY - radius, middleX + radius, middleY + radius), -90, angle, true, new Paint {
