Autoplot Application (#{tag})

Dataset scheme for representing X,Y,Z buckshot data is supported in the SeriesRenderer. The page http://autoplot.org/Cooking_at_LANL shows how to make this plot.
Autoplot attempts to allow plotting of data from many data sources, including local files and OpenDAP servers.
Datasets are identified with URIs, and by the URI's extension a module is used to load the data into the internal data model. Data is then
displayed by guessing the rendering method and axis ranges to provide a reasonable, useful view of the data.
This is the Autoplot2011 branch. This is an update to the production version containing bugfixes and minor new features.
Single-jar version, autoplot.jar, can be run without network access and from the command line. Note CDFs are only supported
via the Java-based reader and Autoplot will attempt to use it when the C-based version is not available.
Bugfixes:
- 3469219: handle units in append. For example LANL has files where timetags are always from start of day
- bugfix: Turns out "ms since 1992-09-13T00:00" in a QStream would not be interpreted as a time. Now SemanticOps.lookupUnits is used.
- bugfix: rank3 copyValues IDL/Matlab adapter failed because the length(i0) was used instead of length(i0,i1), leaving result mostly zeroes.
- bugfix: migrate changes from the CDF Java library to support the same virtual variables
- 3469880: tooltips should go on field labels, not on the label itself.
- bugfix: getParam( 'timerange', '1997-Jan' ) wouldn't support TimeSeriesBrowse because "Jan" was not [a-z]*
- updates to auralizeTool so that it works again
- clean up aggregate GUI, so previews are shown and one code is used to form aggregations
- bugfix: extra messages "autolayout was set to false" because all prefs were read just to get NN
- profiling to find problem spots for long batch runs
- limit undo list to 100 states to support long batch runs
- 3471016: move more GUI operations to event thread to avoid deadlocks
- ytagsDataSet gave Y[X] -> indgen() instead of Y.
- bugfix: digital renderer color was not bound to foreground color.
- bugfix: rank 2 [:,[X,Y,Z]] scheme supported in SeriesRenderer.
- update contour function to return bundle [:,[X,Y,Z]]
- bugfix: python supports ds[:,0] as unbundle, before it would drop metadata making it useless for bundles
- bugfix: in plotx, allow symbol='stars' by loosing up code that looks for values in enumeration
- bugfix: guard against ordinal units getting into axis setting.
- bugfix: rank 4 was never coded for TrimStrideWrapper.java, so python ds[:,:,:,4:6] would fail, clean up to today's qdataset
- bugfix: python supports ds[:,0] as shorthand for unbundle, before it would drop metadata making it useless for bundles
Older Bugfixes:
- bugfix: qstreams would not look up time location units like "ms since 1992-09-20T00:00:00.000Z"
- 3237397: gaps in das2 spectrograms
- 3469219: handle units in append. Before we would assume the units were unchanging and wouldn't check for this.
- bugfix: UNITS were set in Jython applyBinaryOp, when the caller should set the units. This would result in "200 s" / "10 s" = "20 s"
- bugfixes with CDF reader metadata with high-rank CDF files.
- bugfix: where didn't check for fill data, and eq returns fill.
- bugfix: improvements to NN rendering, where single points were not enlarged
- bugfix: old kludge for dimensionless values in vap files removed to fix pitch angle distributions
- bugfix: pitch angle distribution renderer was flipped left-to-right! This is still young code. Please let us know if you were affected!
- bugfix: bottom plot can provide context for top plot when connector is used.
Features:
- guessNameFor(URI) introduced, and Jython script getDataSet completion attempts to suggest better name than "ds"
- add fftPowerDelta1024 to CDF virtual variable functions
- improve support for filesystem completions like .../1wire/dot4_data/$Y/$m/$d/10.<COMP>
- LSpec code updated to work with today's Autoplot, and included in single-jar release
- NetCDF/HDF5 reader supports constraints like ds[0:10] to allow read of huge files.
- box zoom detected and described efficiently in undo list
- add Ops.flatten function, before we had only flattenRank2
- introduce SemanticOps.getLooseUnitsConverter, which allows a ratiometric unit to be compared to a dimensionless. (2 kg).gt(1)
- simplify code and allow ds[r] to be used where ds is rank 2 and r is rank 1
Less recent features:
- add mkdir function to ScriptContext.
- getDataSet completion in Jython editor guesses default name from URI instead of "ds"
- support ISTP metadata in NC and HDF5 files for LANL
- automatically treat -1e99 as fill in NC and HDF5 files.
- handle ISO8601 formatted times in HDF5 and NC files. The CDF folks and LANL were both producing files like this.
- add icon for events renderer
- writeToPng and writeToPdf in scripts will now make the directory if it doesn't exist.
Known issues:
This completes the feature set for the new production branch. No major features will be added before branching this version. A production branch will be started in a couple of weeks, and the "Start Autoplot" link at the top of www.autoplot.org will run this version. Feedback on the function and quality of this release is greatly appreciated!

This is not complete, and limitations include:
- Quantities of rank 3 dimensionality (e.g. flux(Time,Energy,pitch) are plotted by slicing.
- Quantities of rank 4 dimensionality (e.g. flux(Time,Energy,azimuth,sector) are plotted by slicing twice.
