SGPLOT and Shading of Forecast Area

BCNAV — Sun, 04 Jun 2017 21:29:27 GMT

Hi all,

I'd like to be able to shade an area when using sgplot. Specifically, if I know my forecast will start January 1, 2016, I'd like to shade all areas to the right of that date with light gray shading in the background (not covering the forecast line graph).

Thanks in advance

-Bill

I'll leave the tweaking of the options up to you, but here's a demo on how to get started using a SASHelp dataset.

BAND is the statement in PROC SGPLOT that you're looking for, fillattrs seems to control the transparency and colour, which will be important.

proc sgplot data=sashelp.stocks;
where stock ='IBM';
scatter x=date y=open;
band y=open lower="01Jan2000"d upper= "01Jan2006"d / fillattrs=(color = red transparency=0.5) ;
run;quit;

In general if you're looking for Graph Examples, see the SAS Graph Gallery or robslink.com for many, many samples.

You might want to use a BLOCK plot for this type of display. Here is a simple example:

data air;
set sashelp.air;
lenth shade $ 8;
if date >= '01jan1957'd then shade="Forecast";
else shade="Actual";
run;

proc sgplot data=air;
block x=date block=shade / filltype=alternate fillattrs=GraphAltBlock altfillattrs=GraphBlock;
series x=date y=air;
run;

See http://support.sas.com/documentation/cdl/en/grstatproc/69716/HTML/default/viewer.htm#n0ikbvq5nwz6ezn1czzi40aw048o.htm for more syntax options.

Hope this helps!

Dan

See the example and code in the article "Highlight forecast regions in graphs."
