Hi Kare: I think automatic drawing of legends is missing right
now in the underlying PLplot library. I know there is work going on to
add this feature.
Once that is done, myself (or some other generous developer) would have to
find time to add the perl bindings.
So, I think this is on the horizon, but is not supported yet.

Doug

Hi!
Derek's suggestion of installing some plplot9-driver-* packages just worked
fine :)
I just realised that legends is not straight forward with plplot. But nothing
is impossible so I thought it could be an idea to set up a view port to the
right of a plot which is a result of this call:
$pl1->xyplot($x,$y, VIEWPORT => [0.15, 0.80, 0.15, 0.85]);
and then plot the legend "excell like" box to the right of the main plot in a
viewport defined with these coordinates
[0.85, 0.95, 0.15, 0.85]
and plot legends in this tiny view port with axes scaled from 0 to 1 for
simplicity.
Well, at least for me, this turned out very messy in the end... isn't ther a
standard way to put up a view port with pre scaled axes that are not drawn
in the view port?
Rergards,

Hi Edvard: This has to do with the drivers installed with plplot. It
looks like plplot was not installed with the JPEG library. Did you
compile and install plplot yourself, or did you use an Ubuntu package?
My recipe for building plplot looks something like this:
(untar plplot package and change to that directory)
export PKG_CONFIG_PATH=/usr/lib64/pkgconfig:/usr/lib/pkgconfig
cmake -DCMAKE_INSTALL_PREFIX=/usr/lib -DPLD_png=ON -DPLD_jpeg=ON
-DPLD_memcairo=ON -DDEFAULT_NO_BINDINGS=ON -DENABLE_cxx=ON -DPLD_pngcairo=ON
-DPLD_pscai
ro=ON -DPLD_pdfcairo=ON CMakeLists.txt
make
This works for me on CentOS (RedHat enterprise clone) with libjpeg and
cmake installed.
I think you should be able to install a new plplot underneith the PDL and
PDL::Graphics::PLplot installation and it should still work.
Do any Ubuntu users have any quick suggestions?
