带有移动平均线的烛台图表在Matlab中

Question

运行此代码时，出现错误“使用ReadTableMinMaxMovingAverage时出错 数据输入必须与轴配置匹配。数字轴必须具有数字数据输入或 可以转换为两倍的数据输入”。 请告知。

        Low_Gate=tbl.PX_LOW;
        High_Gate=tbl.PX_HIGH;
        Open_Gate=tbl.PX_OPEN;
        Last_Gate=tbl.PX_LAST;


        meridian_price=(Low_Gate+High_Gate)/2;
        ma_medianPrice13 = movavg(meridian_price,'simple',13);
        ma_medianPrice8 = movavg(meridian_price,'simple',8);
        ma_medianPrice5 = movavg(meridian_price,'simple',5);


        %candle(High_Gate,Low_Gate,Last_Gate,Open_Gate)
        grid on
        hold on
        plot(Date,ma_medianPrice13)
        plot(Date,ma_medianPrice8)
        plot(Date,ma_medianPrice5)
