[求助]解盤部分不顯示數(shù)值，應(yīng)該如何寫才對，請指教？　[金字塔]

{主力控盤法}
M5:ma(c,5),colorwhite;
m20:ma(c,20),coloryellow;
M60:MA(C,60),colorgreen;
p1:=SYSPARAM(1);
{金叉}
均線金叉:=cross(m5,m20);
wzm:=sumbars(均線金叉,1);
金叉關(guān)鍵高點(diǎn):=max(ref(h,wzm),ref(h,wzm-1)),linethick0,COLORMAGENTA;
金叉關(guān)鍵低點(diǎn):=min(ref(l,wzm),ref(l,wzm-1)),linethick0;
{PARTLINE(backset(islastbar,wzm-1),金叉關(guān)鍵低點(diǎn));}
PARTLINE(backset(islastbar,wzm-1),金叉關(guān)鍵高點(diǎn)),COLORMAGENTA;
DRAWTEXT(ISLASTBAR ,金叉關(guān)鍵高點(diǎn),'均線金叉'),COLORMAGENTA,SHIFT1;
DRAWNUMBER(ISLASTBAR,金叉關(guān)鍵高點(diǎn),金叉關(guān)鍵高點(diǎn),2),PXUP30,COLORMAGENTA;
均線金叉突破:(ref(close,1)<金叉關(guān)鍵高點(diǎn)  or open<金叉關(guān)鍵高點(diǎn)) and close>金叉關(guān)鍵高點(diǎn),linethick0,COLORMAGENTA;
explain(1,'均線金叉關(guān)鍵高點(diǎn)=',numtostr(金叉關(guān)鍵高點(diǎn),2)),COLORMAGENTA;
explain(1,'均線金叉關(guān)鍵低點(diǎn)=',numtostr(金叉關(guān)鍵低點(diǎn),2)),colorffff;

下面兩句應(yīng)該如何寫才對？

explain(1,'均線金叉關(guān)鍵高點(diǎn)=',numtostr(金叉關(guān)鍵高點(diǎn),2)),COLORMAGENTA;
explain(1,'均線金叉關(guān)鍵低點(diǎn)=',numtostr(金叉關(guān)鍵低點(diǎn),2)),colorffff;

explain(1,'均線金叉關(guān)鍵高點(diǎn)='&numtostr(金叉關(guān)鍵高點(diǎn),2)),COLORMAGENTA;
explain(1,'均線金叉關(guān)鍵低點(diǎn)='&numtostr(金叉關(guān)鍵低點(diǎn),2)),color00ff;

請仔細(xì)看看explain函數(shù)的使用說明
