There is a trick you can use, but it requires that you
restructure your data before feeding it into PROC GPLOT

One of the options on the SYMBOL statement is the
INTERPOL=HILO<C><option>

So you can set up the data so that in the high, low and close
positions, the data values will be the +1 sd, -1 sd and mean.

This is a sketchy description, and I can give you more details
if you need them.

Subject: Standard deviation plot with groups

I would like to create a standard deviation plot showing the mean with
lines showing +/- the standard deviation for groups arranged by day. I
want these all on the same chart.  I have the variables group, day and
temperature. Is there any way to do this without rearranging the data?
In
the past I have created a new variable "group/day" so that I could plot
these side by side, but it is cumbersome.

I have tried to create with proc gplot, but I cannot figure out how to
have two grouping variables. I could use bar charts with proc gchart to
convey this information, which is pretty straightforward, but I don't
like
the bar charts very much for displaying information about means.

Thanks in advance.
