Plz help in putting Zigzag into background !!

Hello Experts;

Trying to convert the following zigzag display code into background;

int init()
{
IndicatorBuffers(3);
//---- drawing settings
SetIndexStyle(0,DRAW_SECTION);
//---- indicator buffers mapping
SetIndexBuffer(0,ZigzagBuffer);
SetIndexBuffer(1,HighMapBuffer);
SetIndexBuffer(2,LowMapBuffer);
SetIndexEmptyValue(0,0.0);

//---- indicator short name
IndicatorShortName("ZigZag("+ExtDepth+","+ExtDeviation+","+ExtBackstep+")");
//---- initialization done
return(0);
}

How should I put Objectset( OBJPROP_BACK, true) ??

Any help appreciated !!

ObjectSet(....) can be applied only to objects, not indicators. From the code you've shown in your post (SetIndexBuffer etc), it looks very much like your Zigzag is an indicator.
