Both the FileReporter, which produces a space separated value text file
including headers labeling each column as the NetcdfReporter which produces
binary netcdf files can directly be opened using KST, KST will use the
headers to interprete the data. All that is left is creating plots in
which you need to choose what needs to be on the X-axis and what needs to
be on the Y-axis. You can save the plot-layout for later use so you do not
have to redo the variable selection later on. For live plotting I would
recommend the NetcdfReporter due to lower CPU usage.

Both reporters need to be configured to indicate which Component Port data
needs to be recorded. In case of non-primitive data types you will need to
generate or create a typekit for the serialization of the data into the
report-files.
In most use-cases there is little to no c++ code involved in the entire
setup.

About the plotting part, you can use KST: http://kst-plot.kde.org/.
I didn't test it myself but I would be interested in getting some feedback
on how to plug the marshaller into KST.
