Spread out display of prices in window

each price is the last price of a specific curve. PlotText requires offset pixels and I don't know know how to transform price into pixel. Below function try to do that.

function Plot_MIDAS( sr_id, lbar )
{
    global midasColor, midasShapeDigit, lastBar, Price_PksVal, Price_BotVal, alertPct, sayAlert, eEmail, Price; //xAxis, ypixels,S2_Trigger,

    VisibleBarCount = lastvisiblebar - firstvisiblebar;
    yLowest = GetYLowestSupport( L , VisibleBarCount );
    yHighest = GetYHighestResistance( H, VisibleBarCount );
	DeltaMaxMinPrice = yHighest-yLowest;

//    m_ID = "S" + sr_id;
//    m_ID = "";
	yAxisDelta = Status ( "axismaxy" ) - Status ( "axisminy" );
    yp = IIf( sr_id <= S8, -20, 20 );
	if (sr_id <=8) {
		yTextOffset = 0;//(Status ( "pxchartheight" )/2 - ((8-sr_id)*100)); // start from top pixel of chart
//		_trace("pxchartheight_" + Status ( "pxchartheight" ));
	}
	else {
		yTextOffset = 0; // (Status ( "pxchartheight" )/2 - ((sr_id-8)*5)); // start from top pixel of chart
//      _trace("pxchartheight_" + Status ( "pxchartheight" ));
	}

//	yTextOffset = (DeltaMaxMinPrice/16) + yLowest; // start from yLowest pixel of chart

    midas_array = generate_MidasSR( lbar );  // generating curve using existing launch bar point.
    Plot( midas_array , "", midasColor[sr_id], styleLine | styleThick );
    PlotShapes( ( lbar + 1 == xAxis ) * midasShapeDigit[sr_id], midasColor[sr_id], 0 , midas_array, yp );
//	PlotTextSetFont( NumToStr(LastValue(midas_array),1.2), "Tahoma",8, (lbar + 1), LastValue(midas_array) , colorGold , colorDefault, -5); //
//	PlotText( NumToStr(LastValue(midas_array),1.2), LastValue(BarIndex())+1, LastValue(midas_array) , colorBlack , midasColor[sr_id], -1); //
	PlotText( NumToStr(LastValue(midas_array),1.2), LastValue(BarIndex())+1, LastValue(midas_array) , colorBlack , midasColor[sr_id], yTextOffset); //	

    if( 0 && (sr_id == S1 || sr_id == R1) )
        PlotShapes( ( xAxis == lastBar ) * midasShapeDigit[sr_id], midasColor[sr_id], 0 , midas_array, IIf( sr_id == S1, -12, 12 ) );

    if( eEmail )
    {
        triggerThreshold = midas_array * ( alertPct / 100 );

        PksTrigger    = barssince( Price_PksVal >= ( midas_array - triggerThreshold ) AND Price_PksVal <= ( midas_array + triggerThreshold ) );
        BotTrigger    = barssince( Price_BotVal >= ( midas_array - triggerThreshold ) AND Price_BotVal <= ( midas_array + triggerThreshold ) );

        trigger_array = PksTrigger OR BotTrigger;

        If( Interval() == inDaily )
        curr_interval = " Daily ";
        else
            curr_interval = " Weekly ";

        touch_S = cross( Price, midas_array ) || ( Price / midas_array ) <= ( 1 + alertPct );
        touch_R = cross( midas_array, Price ) || ( midas_array / Price ) <= ( 1 + alertPct );
    }

    if( sr_id <= 8 )
    {
//        sr_id = sr_id; // S curve start at 1
        SayNotTooOften( Name() + "  S" + sr_id , sayAlert );

        if( eEmail )
            AlertIF( barssince( touch_S ) <= 10, "EMAIL", FullName() + curr_interval + "Touch Bottom S" + sr_id, 1 );
    }
    else
    {
        sr_id = ( 17 - sr_id );
        SayNotTooOften( Name() + "  R" + sr_id , sayAlert );

        if( eEmail )
            AlertIF( barssince( touch_R ) <= 10, "EMAIL", FullName() + curr_interval + "Touch Top R" + sr_id, 1 );
    }
}
