[gradsusr] how to plot map only

[Lacroix Christelle]

Hi,

I would like to plot a map with political boundaries but without datas, 
is it possible?

I have theses commands:
'set mpdraw on'
    'set poli on'
    'set mpt 0 -1'
    'set mpt 1 -1'
    'set gxout shaded'
    'set clevs 0 4 6 8 10 12 14 16 18 20 22 24 26 28 32 36 40 44 48 52 
70 100'
    'set ccols 34 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 
35 65'
    'd (pow((pow(UGRD10m,2)+pow(VGRD10m,2)),0.5))*1.944'
    'set gxout barb'
    'set ccolor 1'
    'set cthick 7'
    'set arrscl 0.1'

    'd maskout(skip(UGRD10m*1.944,'skip'),LANDsfc*(-1)) ; 
maskout(skip(VGRD10m*1.944,'skip'),LANDsfc*(-1))'
    'q ll2xy 'lonlogo' 'latlogo''
    xs = subwrd(result,1)
    ys = subwrd(result,2)
    xs3 = xs * 720 /11 - 22
    ys3 = 576 - (ys *576 /8) - 42
    'set line 3 1 1'
    'draw mark 3 'xs' 'ys' 0.15'
    'set string 7 tc 5 0'
    'set strsiz 0.15'
    'draw string 'xs' 'ys' Leader'
