As indicated by Christine this is not possible just now, but there is a
"work around".

task: Show proportion of cases among those exposed to a number of
exposures, e.g. OYSTERS PRAWNS CHICKEN in a graph. But DO NOT show among
those in each individual exposure NOT exposed.

1. Create a standard ci plot
   ciplot case OYSTERS PRAWNS CHICKEN /notot
            (notot if you wish to exclude the overall)

2. Paste into a graphing or word processor immediately after creating the
         (shift to that other software and press - ctrl+V)
          Do not rigth click on graph and copy - this will create a bmp file.

3. Edit graph in that software
    a   Here you would delete the parts of the ciplot shown for "non
exposed" to
       each exposure.
    b create a "nice" x-axis indicating the 10 exposures.

4. If you cannot do point 2-3 due to problems create a "BMP" by right
  on the graph and paste into a drawing software, e.g. GLIMP.
    Then use an erase or white pencil and move those parts not desired.
