mKChartView.addChildDraw("KDJ", mKDJDraw);- 重写 drawTranslated（在此方法中绘画的会滑动和缩放） 方法 ，如下所示：

*/
private void drawMACD(Canvas canvas, BaseKChartView view, float x, float macd) {
float macdy = view.getChildY(macd);
float r = mMACDWidth / 2;
float zeroy=view.getChildY(0);
if (macd > 0) {
canvas.drawRect(x - r, macdy, x + r, zeroy, mRedPaint);
} else {
canvas.drawRect(x - r, zeroy, x + r, macdy, mGreenPaint);
}
