Have you tried using the GRAPH command to produce your error bars? It draws much better and uses much less memory which can be a problem if you are going to produce a lot of charts.

Subject: Error Bar mis-alignment when using IGRAPH
Please forgive me if this has been answered. I did search before posting and
can't believe I'm the only one having trouble with this.
When I make an IGRAPH line graph and add error bars (1 SE), it sometimes
puts the error bars on a point to the left of the line. It looks as though
it "misses" the point.
It doesn't always do this, and I can't figure out what I'm doing to cause
it.
I run SPSS 14.
Here is the syntax I use and a general picture of what I'm getting:
IGRAPH /VIEWNAME='Line Chart' /X1 = VAR(LearningStg) TYPE = CATEGORICAL /Y =
VAR(comp_acc) TYPE = SCALE /COLOR = VAR(FBgate) TYPE = CATEGORICAL
/COORDINATE = VERTICAL /X1LENGTH=4.0 /YLENGTH=4.0 /X2LENGTH=4.0
/SCALERANGE = VAR(comp_acc) MIN=0.500000 MAX=1.000000 /CATORDER
VAR(FBgate) (ASCENDING
VALUES OMITEMPTY) /CATORDER VAR(LearningStg) (ASCENDING VALUES OMITEMPTY)
/LINE(MEAN) KEY=ON STYLE = LINE DROPLINE = OFF INTERPOLATE = STRAIGHT
BREAK = NONE /ERRORBAR SE(1.0) DIRECTION = BOTH CAPWIDTH (45) CAPSTYLE =
T.
EXE.

Has anyone come across this before? Is this a "feature" instead of a
problem? :-)
