I am trying to plot a shapefile which contains multiple elements. I <br>
queried the shp and dbf files as follows:<br>
<br>
<br>
ga-> q shp current_warnings<br>
Shapefile Type=Polygon #Shapes=4 XBounds=-88.9:-86.86 YBounds=29.38:37.16<br>
0: Polygon parts=1 vertices=5 XBounds=-88.05:-86.86 <br>
YBounds=29.38:30.01 ZBounds=0:0 MBounds=0:0<br>
1: Polygon parts=1 vertices=19 XBounds=-88.49:-87.05 <br>
YBounds=36.5:37.16 ZBounds=0:0 MBounds=0:0<br>
2: Polygon parts=1 vertices=8 XBounds=-88.9:-88.36 <br>
YBounds=31.43:31.63 ZBounds=0:0 MBounds=0:0<br>
3: Polygon parts=1 vertices=11 XBounds=-88.35:-88.01 <br>
YBounds=32.05:32.25 ZBounds=0:0 MBounds=0:0<br>

<br>
However, I can not figure out how to plot this with different colors for <br>
each element (SVR, SMW, etc...). I have tried the following code which <br>
plots everything in the shapefile...<br>
<br>
<br>
'set rgb 1 255 0 0 255'<br>
'set shpopts -1'<br>
'set line 1 1 1'<br>
'draw shp current_warnings'<br>
<br>
<br>
But I need to know how to draw each kind of element separately (SVR, <br>
SMW, etc...).<br>
<br>
Thanks,<br>
