The indicator array values that are to the left of the given bar will not be shown in the chart or in the DataWindow. 0 will be set as default, and all data will be drawn.

Parameters:

index	-	Line index. Must lie between 0 and 7.
begin	-	First drawing bar position number.

Sample:

int init()
  {
//---- 2 additional buffers are used for counting.
   IndicatorBuffers(3);
//---- drawing settings
   SetIndexStyle(0,DRAW_HISTOGRAM,STYLE_SOLID,3);
   SetIndexDrawBegin(0,SignalSMA);
   IndicatorDigits(MarketInfo(Symbol(),MODE_DIGITS)+2);
//---- 3 indicator buffers mapping
   SetIndexBuffer(0,ind_buffer1);
   SetIndexBuffer(1,ind_buffer2);
   SetIndexBuffer(2,ind_buffer3);
//---- name for DataWindow and indicator subwindow label
