I know this is minor but I'm going crazy. Why doesn't it recognize SYMBOL command?
proc sgplot data=Meanx;
where Month in(6);
series x=Hour y=Load / legendlabel = 'Load' MARKERS LINEATTRS = (THICKNESS = 2 PATTERN = SOLID COLOR = LIGHTBLUE SYMBOL = CIRCLEFILLED)
MARKERATTRS = (COLOR = LIGHTBLUE SYMBOL = CIRCLEFILLED);
series x=Hour y=Temperature / y2axis legendlabel = 'Temperature' MARKERS LINEATTRS = (THICKNESS = 2 PATTERN = SOLID COLOR = PINK);
XAXIS LABEL = 'Hour' GRID VALUES = (0 TO 23 BY 1);
YAXIS LABEL = 'LOAD (MW)';
Y2AXIS LABEL = 'Temperature (degrees F)';
run;
