有个公式同时有ma指标和macd或KDJ指标（怎么画图）

我之前写过一个布林和MACD的，把具体指标改下就可以的。 Params Numeric Length(20); //布林周期 Numeric Offset(2); //标准差倍数 Numeric FastLength(12); //MACD参数1 Numeric SlowLength(26); //MACD参数2 Numeric MACDLength(9); //MACD参数3 Vars Plot plt1; //主图plt1 Plot plt2; //主图plt2 Array<Numeric> xData; //x轴数据集 Array<Numeric> yData; //y轴数据集 Series<Numeric> MdLine; //布林中轨 Numeric Band; Series<Numeric> MACDDiff; //MACDDiff Numeric AvgMACD; //MACDDEA Numeric MACDValue; //MACD Events OnInit() { plt2.figure(0); plt2.setOption("plt2","x-format","time"); } OnBar(ArrayRef<Integer> indexs) { MdLine = AverageFC(Close,Length); Band = StandardDev(Close,Length,2); xData[0] = Date+Time; yData[0] = MdLine; plt1.setOption("MdLine","color",Magenta); plt1.line("MdLine",xData,yData); yData[0] = MdLine + Offset * Band; plt1.setOption("UpLine","color",Yellow); plt1.line("UpLine",xData,yData); yData[0] = MdLine - Offset * Band; plt1.setOption("DnLine","color",Cyan); plt1.line("DnLine",xData,yData); yData[0] = 0; plt2.line("零线",xData,yData); MACDDiff = XAverage( Close, FastLength ) - XAverage( Close, SlowLength ) ; yData[0] = MACDDiff; plt2.line("MACDDiff",xData,yData); AvgMACD = XAverage(MACDDiff,MACDLength); yData[0] = AvgMACD; plt2.line("MACDDEA",xData,yData); MACDValue = MACDDiff - AvgMACD; yData[0] = MACDValue; If(yData[0]>=0) { plt2.setOption("MACD","color",Red); } Else { plt2.setOption("MACD","color",Green); } plt2.barv("MACD",xData,yData); }
