How to change styles ( color/ pattern of lines/ symbols/ font/ fntsiz) in graphs using Proc Template

[SASuserlot]

Hi I am newly learning into Proc Template  to create different graphs. I want to know how I can control the  graph styles such as line colors, line pattern, symbols,  fonts used in the graph. can you please guys suggest me what to do in the following code. I tried at SAS, but for me it looks too vast  and some times going over my head 😪.

ODS LISTING CLOSE;
data cars;
set sashelp.cars;
engine=enginesize;
run;
PROC MEANS DATA= cars;
 CLASS origin engine;
 VAR horsepower;
 OUTPUT OUT=summary (WHERE=(_type_ EQ 3)) N=n MEAN=mean STDDEV=stddev MIN=min
MAX=max;
RUN;
ODS LISTING;
DATA summary;
 SET summary;
 IF UPCASE(origin) EQ 'ASIA' THEN engine = engine-0.1;
 IF UPCASE(origin) EQ 'USA' THEN engine = engine+0.1;
RUN;


PROC TEMPLATE;
 DEFINE STATGRAPH errorbar;
 BeginGraph;
 EntryTitle "PhUSE 2010";
 EntryTitle "Example Error Bar (Mean " {UNICODE '00B1'X}
 " SD) Plot Using GTL";
 Layout OVERLAY /
 XAxisOpts=(LABEL="Engine Size")
 YAxisOpts=(LABEL="Mean Horsepower");
 ScatterPlot X=engine Y=mean /
 GROUP=origin NAME="scatter"
 YErrorLower=EVAL(mean-stddev);
/* YErrorUpper=EVAL(mean+stddev);*/
 SeriesPlot X=engine Y=mean / GROUP=origin;
 DiscreteLegend "scatter" / ACROSS=3 TITLE="Origin of Car";

 EndLayout;
 EndGraph;
 END;
RUN;


options orientation = landscape errors = 2 missing = ' ' nofmterr ls = 175 validvarname = upcase nofmterr nobyline 
noquotelenmax ;
ods escapechar = '^';
ods results on; 
ods listing close; 
ods rtf file = "\\xx\D\xx\Desktop\Graphs\sed-err-anno.rtf" style = table_rtf;* nogtitle nogfootnote;

PROC SGRENDER DATA=summary TEMPLATE=errorbar;
RUN;
ods rtf close;
ods listing close;

I am looking to change the color and pattern of the lines and symbols and the font in x axis y axis labels and legends in the following graph. I really appreciate your help and advise

First of all, there is not need to use the Graph Template Language (GTL) to create this graph. Proc SGPLOT will do this with less code.

To control elements in your plots I recommend to have a look at these blogs:
