Visualization Packages and Data Output Formats

pyGraph: Animated, Easy Client for 1D Line Plots

pyGraph pygraph is a PyQt re-implementation of xGraph and yGraph

Gnuplot - Powerful Visualization Tool for 1D and 2D Data

Gnuplot is a command-driven interactive function plotting program. It can plot functions and data points in both two- and three-dimensional plots in various formats (points, lines, surfaces, contours).

VisIt

VisIt is a state-of-the-art data visualization tool based on the open source visualization class-library VTK and is developed and maintained at the Lawrence Livermore National Laboratory, University of California. VisIt is a uniquely powerful, full-featured software package for the visualization of scientific, engineering and analytical data: Its open system design is built on a standard interface environment. And its sophisticated data model provides users with great flexibility in creating visualizations.

Cactus Postprocessing Utilities

To aid the visualisation of very large HDF5 output data, thorn ExternalLibraries/HDF5 provides a set of utility programs which can be used to manipulate HDF5 files, independently of their driver-specific format:

• hdf5_double_to_single
  Copies the entire contents of an input HDF5 file to an output HDF5 file, converting all double precision datasets to single precision.
• hdf5_merge
  Merges a list of HDF5 input files into a single HDF5 output file. This can be used to concatenate HDF5 output data created as one file per timestep.
• hdf5_extract
  Extracts a given list of named objects (groups or datasets) from an HDF5 input file and writes them into a new HDF5 output file. This is the reverse operation to what hdf5_merge does. Useful eg. for extracting individual timesteps from a time series HDF5 datafile.
