SAS gmap choro with two dummy viariables 1 color and 1 pattern

[Dim13]

Hello Everybody,

I need to figure out how to create a world map where two dummy variables (1-0) are plotted on one world map.  I need either:

1.  color variation for one variable and pattern variation for the second or

2.  pattern variation for one variable and country "perimeter" bolding for the other.

My current code to plot the first variable named potential1 is:

proc gmap data=ma3 map=mapsgfk.world gout=gseg ;
id idname;
choro potential1 / levels=2 coutline=black name='map1a' ;
pattern1 v=solid repeat=48;
run;

Thanks eveybody

If you want things to change in a choro plot then you only have one variable to use. So you may need to combine the values of the two variables to create each combination.

Changing Border appearance conditionally I have only been able to do with annotate data that basically traces the border with different properties. If you want the outline color to match the pattern filling the area use COUTLINE=SAME. If by "bolding" a border you want all borders the same width use the WOUTLINE= option. If you want different widths then you'll need to go the annotate route.

Another option is to use the map data set to create Polygon plots in SGPLOT and use a DATTERMAP data set to set properties for the polygons. Again that would use a single variable but I believe that would let you set the associated "border", with polygon it is outline, color, line pattern and thickness.

In any case adjacent borders may have issues with differing widths/color and which is drawn over the other using the same coordinates.

Thanks,

I guess I had not thought of combining them into one variable - since it is only two dummy variables.  I think this will work.

Will do so,

thanks again,
