GraphGDIPlus not showing values

[marko001]

Hi all guys,

I have three graphs in my GUI, each of them defined with GDIPLUS, here an example of just one of them:

 

Func _drawVOLUME($x = 0, $y_startVOL = 0)
    If $GraphVolumesCreated = 0 Then
        $aGraphV = _GraphGDIPlus_Create($MainGUI, 830, 361, 1076, 114, 0xFF000000, 0xFF1B1B1B)
        _GraphGDIPlus_Set_RangeX($aGraphV, 0, $x, $x / 5, 1, 0)
        _GraphGDIPlus_Set_RangeY($aGraphV, _ArrayMin($aMACD, 1, UBound($aMACD) - $x, UBound($aMACD) - 1, 11), _ArrayMax($aMACD, 1, UBound($aMACD) - $x, UBound($aMACD) - 1, 11), 3, 1, 1)
        $GraphVolumesCreated = 1
    Else
        _GraphGDIPlus_Clear($aGraphV)
        _GraphGDIPlus_Set_RangeY($aGraphV, _ArrayMin($aMACD, 1, UBound($aMACD) - $x, UBound($aMACD) - 1, 11), _ArrayMax($aMACD, 1, UBound($aMACD) - $x, UBound($aMACD) - 1, 11), 3, 1, 1)
    EndIf
    _GraphGDIPlus_Set_PenColor($aGraphV, 0xFF78F900) ; LIGHT GREEN - VOLUMES
    _GraphGDIPlus_Set_PenSize($aGraphV, 5)
;~  _GraphGDIPlus_Plot_Start($aGraph, 0, $y_startVOL)
    For $i = 0 To $x - 1
        _GraphGDIPlus_Plot_Start($aGraphV, $i, 0) ;
        _GraphGDIPlus_Plot_Line($aGraphV, $i, $aMACD[UBound($aMACD) - 1 - $x + 1 + $i][11])
    Next
    _GraphGDIPlus_Refresh($aGraphV)
EndFunc   ;==>_drawVOLUME

as recommeded from UDF I use

WinSetTrans($MainGUI, "", 255)

But more or less randomly it happens that X and Y values on axis don't show (pic uploaded).

IS there a way to solve this?
Thanks,

Marco

@UEZ Sorry to disturb you, I saw you had answers for similar matters in other threads, maybe you can help me to sort it out.

Thanks,

Well @marko001. With this snippet above I cannot tell you what might be wrong. Just create a working example and I will have a look.

The one you see above is the original code, there's nothing particular in the cycle, just 2 adlibregister functions (to call OHLC datas (5mins) and MACD values (10 secs)).

3 graphs to build a) MACD curves, b ) volumes, c) stock value. 

$amacd[$i][12] is the array that contains all stocks data:

;~     0 - Date
;~     1 - Open
;~     2 - High
;~     3 - Low
;~     4 - Close
;~     5 - $short Days EMA
;~  6 - $long Days EMA
;~  7 - MACD (YELLOW LINE)
;~  8 - Signal (RED LINE)
;~  9 - Histogram
;~ 10 - not used
;~ 11 - Volumes
