SGPANEL fix

[matt23]

Hi, I'm playing with sgpanel and I'm I need help.

Can I change colors of individual lines? Also how can I get rid of the connecting lines between first and last point?

Here's the code I have:

proc sort data=ramp;
by Month hour;
run;

proc means data=ramp noprint;
by Month hour;
var delta Temperature;
output out=Meanf mean=;
run;

proc sgplot data=Meanf;
series x=Hour y=delta / group=Month MARKERS LINEATTRS = (THICKNESS = 2 PATTERN = SOLID);
XAXIS LABEL = 'Hour' GRID VALUES = (0 TO 23 BY 1);
YAXIS LABEL = 'LOAD RAMP(MW)';
title 'Monthly Load Ramp Summary';
run;

proc format library=work;
value season
12,1,2 = 'Winter'
3,4,5 = 'Spring'
6,7,8 = 'Summer'
9,10,11 = 'Fall';
run;

proc sgpanel data=Meanf ;
   panelby month /layout=panel rows=2 columns=2 onepanel ;
   format month season.;
   series x=Hour y=delta / group=Month MARKERS LINEATTRS = (THICKNESS = 2 PATTERN = SOLID) BREAK;
   colaxis label="Temperature (degrees F)";
   rowaxis label="Load Ramp (MW)";
   title 'Load Ramp vs Temperature (overall)';
run;

You might be better off adding a SEASON variable based on your Month. The Format applied to month is honored for grouping in general so you get a single color per season.

The connection is caused most likely  by each month having the same "hour". I would try inserting a record at the end of each month with a missing value for hour and delta to create a break in the series.

Something like:

proc sort data=ramp;
by Month hour;
run;

data ramp1;
   set ramp;
   by month;
   Season= put(month,season.);
   output;
   if last.month then do;
      hour=.;
      delta=.;
      output;
   end;
run;

Use ramp1 with panel by season and don't use the season format in the sgpanel code.
