Many Thanks Adam and Mary.

I applied your suggestions and every thing is going right now.

Louis,

I assume you mean "labelbar" instead of "label"?

If so, there are two possible problems.

One is that you are setting:

   res_at_vpXF      = 0.1
   res_at_vpWidthF  = 0.9
   res_at_vpYF      = 0.9
   res_at_vpHeightF = 0.8

The width is for the plot area only, and doesn't include the area that
contains all the annotations, like tickmarks, tickmark labels, titles,
and labelbars.

You've made the width 0.9, and started the plot at position 0.1,
so the right edge of the plot is now up against the edge
of the viewport. You won't be able to see the labelbar or anything
else to the right of the plot area.

You can try making vpXF smaller, like 0.05, and/or making the
width/height a little smaller.

The second possible problem is that:

   res_at_pmLabelBarOrthogonalPosF = 0.05          ; move label bar closer

may be set to too large a value, causing the labelbar to move outside
the viewport.

Once you fix the above width problem, then you might need to adjust
this value as well. Try these for a start:

   res_at_pmLabelBarOrthogonalPosF =  0.01
   res_at_pmLabelBarOrthogonalPosF = -0.05
