proc gmap: color gradient shading

Anita_n — Fri, 21 May 2021 06:59:10 GMT

Dear all,

am tring to use color grading shades for the map I created but it's not showing any results. Am not sure if I have missing anything in my code. I will appreciate any help

proc template;
define style styles.grad1;
parent=styles.listing;
style threecolorramp /startcolor=cream endcolor=darkblue;
end;
run;

proc gmap data=mydata map=mapsgfk.germany all; 
id id;
choro cases / statistic=first discrete 
levels=4
coutline=gray anno=myanno
cdefault=CXFFFFFF
legend=legend1;
run;
quit;

I suppose you saw this.

I think you forgot to call the style.

you mean this?

ods listing style=styles.grad1;
ods html style=styles.grad1;

yes I tried that but I get colors like red green yellow etc. Although they are not included

Try twocolorramp, rather than threecolorramp.

@GraphGuy This is the code I used but unfortunately no changes. Attached is my data

legend1 label =(position=top j=c h=10pt "Number of cases" )
        value=(f="Arial" h=8pt c=black justify=left)
		origin=(78,18)
		across=1
		position= (right middle)
		offset=(0.5)
		space=1
		mode=reserve
		shape= bar(.17in,.13in )/*width and height*/
		;

proc template;
define style styles.grad1;
parent=styles.listing;
style twocolorramp /startcolor=cream endcolor=darkblue;
end;
run;

ods listing style=styles.grad1;
ods html style=styles.grad1;
proc gmap data=mydata map=mydata all; 
id id;
choro cases/ statistic=first discrete 
levels=4
coutline=gray anno=myanno
cdefault=CXFFFFFF
legend=legend1;
run;
quit;

Hmm ... I'm not sure if levels=4 and discrete can be used together(?)

Rather than "statistic=first discrete levels=4", try just "levels=4".

What does your data look like?

@GraphGuy thanks it worked. I deleted discrete.

@GraphGuy here is my data

the map data is mapsgfk.germany and mapsgfk.germany_attr

Let's stick with one question per thread - this thread was for getting the gradient colors working, and we got that part working 🙂

Please start a fresh question/thread for the next question.
