Note is not displaying on HV window

Hi Support Team,

I have developed script to create Note for element ID and contour value. I have drawn with Clinet handle, but note is not appearing on the Hyperview window. Once I click create new note manually in Note Tab it will show but through script note is not apperaing. Can please look into this issue. I have attached script for your reference.

set t [::post::GetT];

set note_id [elAvg$Wn AddNote]

set n_handle [elAvg$Wn GetNoteHandle noteH$Wn $note_id]

noteH$Wn SetAttachment "element $model_id $maxElemID"
noteH$Wn SetPositionToAttachment true
noteH$Wn SetPosition right
noteH$Wn SetPosition top

noteH$Wn SetPosition 1 1
noteH$Wn SetBorderThickness 1

noteH$Wn SetLabel "Max Contour value"
#noteH$Wn SetText "NodeID {entity.id} \nContour_Value {entity.contour_val}"
noteH$Wn SetText "Element ID $maxElemID \n Contour Value $ElemVal";
#elAvg$Wn Draw

noteH$Wn SetAlignment "left"
noteH$Wn SetTextColor "255 255 255"
noteH$Wn SetBackgroundColor "0 0 0"

noteH$Wn SetScreenAnchor false;
noteH$Wn SetTransparency true;
noteH$Wn SetVisibility true;
elAvg$Wn Draw;
