Scientific Plotting for J2EE

Scientific Plotting for J2EE
The AIDATLD1 package provides a set of tags
to embed scientific plots in web applications. It
is based on JAIDA2, the java implementation of
the AIDA3 interfaces, and it uses the JAS4
plotter. AIDATLD provides tags for creating
a plot area, create plot regions, display data
objects and control the style of the plots. The
supported data objects are tuples, histograms,
sets of data points and functions. Such data
objects can be either created by java code, or
created from the result of a sql query or loaded
from a ROOT5 file via a ROOT daemon. The
AIDATLD tags make it easy to overlay multiple
plots, create download links for the generated
plots to several output formats (gif, pdf, svg,
swf, png etc., provided by the FREEHEP
VectorGraphics6 package) and create image maps on
the generated plots regions. GLAST is
currently making use of the AIDATLD tags in its
System Tests web front end7, through which the
quality of reconstruction software releases is
being monitored, and in its Trending web
application8, to view the trending data from the
satellite.
