I've added some new directories for both data logging directives and data
plotting files. The former are files that can be specified on the JSBSim
standalone command line using the --logdirectivefile=filename option (the
option can be specified multiple times). These files tell JSBSim which
parameters to log, and how often. The data plotting files (in the data_plot/
subdirectory) are files that define specific plots or sets of plots (per
page). The plotting and logging files are named identically to make it
easier to script particular runs where a certain type of data is desired to
be plotted. The data plotting directives in the atmosphere.xml file, for
instance, will log the data that is selected for plotting in the
atmosphere.xml data logging file in the data_output/ subdirectory.
The prep_plot application has been enhanced to support a variety of new
options, and has been made more robust. Also, an MSVC++ project file has
been created for that application. Instructions for building prep_plot under
cygwin/linux is included in the comments in the prep_plot.cpp file itself.
The prep_plot produces output for gnuplot. You don't really need prep_plot
to plot the .csv files produced by JSBSim with gnuplot, but I personally
find it much easier to specify plots using an XML syntax rather than build
gnuplot scripts. Prep_plot produces gnuplot scripts that produce plots with
a consistent appearance.
I hope these are useful for you. Comments solicited.
