[gradsusr] Plotting Shapefiles with multiple elements

[Jason M. Warren]

Hello,

I am trying to plot a shapefile which contains multiple elements.  I 
queried the shp and dbf files as follows:


ga-> q shp current_warnings
Shapefile Type=Polygon #Shapes=4 XBounds=-88.9:-86.86 YBounds=29.38:37.16
0:  Polygon  parts=1  vertices=5  XBounds=-88.05:-86.86 
YBounds=29.38:30.01  ZBounds=0:0  MBounds=0:0
1:  Polygon  parts=1  vertices=19  XBounds=-88.49:-87.05 
YBounds=36.5:37.16  ZBounds=0:0  MBounds=0:0
2:  Polygon  parts=1  vertices=8  XBounds=-88.9:-88.36 
YBounds=31.43:31.63  ZBounds=0:0  MBounds=0:0
3:  Polygon  parts=1  vertices=11  XBounds=-88.35:-88.01 
YBounds=32.05:32.25  ZBounds=0:0  MBounds=0:0

However, I can not figure out how to plot this with different colors for 
each element (SVR, SMW, etc...).  I have tried the following code which 
plots everything in the shapefile...


'set rgb 1  255 0 0 255'
'set shpopts -1'
'set line 1 1 1'
'draw shp current_warnings'


But I need to know how to draw each kind of element separately (SVR, 
SMW, etc...).

Thanks,
