New script used to study CDF internal layout.

Autoplot allows plotting of data from many data sources, including remote CDF files and HAPI servers. Datasets are identified with URIs, and by the URI's extension, data are loaded into the internal data model. Data are then displayed by guessing the rendering method and axis ranges to provide a reasonable, useful view of the data. Data can then be additionally processed with other operations like smooth and FFT, and Jython scripting provides a capable programming environment.

This is the Autoplot v2022a branch. This is an update to the production version containing bugfixes and minor new features. Java 8 is now required.

Run with 1GB of memory to support 32-bit Java versions, and run off of ci-pw build server: autoplot_1GB.jnlp

Bugfixes (2022-09-23 r26747):

• skip the cadence check when there are 100,000,000 or more points and the x ds are just indices.
• 2453: correction in loading of CDFs which prevented huge (>2GB CDFs) from being loaded and data exported.
• editor tools scripts were loaded on the event thread, causing hang when internet is not available.
• 2476: validate check on BINS_1 min<max resulted in test148 failing.
• 2475: kludgey solution for pngwalks with $Y$m$d_$x. This will be studied again soon. Thanks, Sadie!
• CDF GUI doesn't offer rank 3 datasets for X and Y.
• special (kludgey) code to prevent "createScreenShot.jy" from loading automatically.
• 2134: rank 1 indices for rank 2 dataset was incorrectly implemented.
• Correction to fast branch for reduceMean.

Older Bugfixes (2022-08-13 r26726):

• 2471: Firebird JSON headed ASCII contained invalid reference and couldn't be used, make more permissive to keep what is correct.
• Delay initialization of CDAWeb database if we already know the dataset and parameter, since it takes 20-30 seconds to initialize.
• 32: Das2 waitUntilIdle loop wouldn't properly block when ephemeris was loading, causing glitches in automated testing and PNG Walks.
• bundle from HAPI exported to CDF would fail because of careless check of dataset type.
• 2470: Rich ASCII (JSON headed ASCII) detects ISO8601 automatically, to match SpacePy.
• 28: Corrections to DataPointRecorder, which sorted numbers alphabetically, not numerically.
• Improved support for decimal year. Thanks, Bill!
• fast branch added for reduceMean of ds[N,2], avoiding use of slow iterator for frequently-occurring operation.

Features:

• 35: Improve support for DEPEND_0 with bins data set.
• 18: New tick logic used on one or two-cycle log axes.

Less recent features:

• Preserve string array properties in JSON headed ascii, and preserve unrecognized properties in USER_PROPERTIES.
• add mime type for PDS lblx files.
• Add withinSet function which returns one where the data is within a set of values.

Data is input from:

• ASCII files (.dat,.txt)
• CSV files (.csv)
• Binary files (.bin)
• CDF files(.cdf)
• PDS4 files (.lblx)
• Excel spread sheets (.xls)
• das2Streams (.d2s or .das2Stream)
• HAPI Servers (vap+hapi:)
• CDAWeb data server (vap+cdaweb:)
• das2servers (vap+das2server:)
• QStreams (.qds) (serialized version of internal model QDataSet)
• Plasma Wave Group das2 Server
• NetCDF files (.nc,.ncml)
• HDF5 files (.h5,.hdf5)
• DODs servers (.dds)
• Cluster Exchange Format files (.cef)
• Fits Format Files (.fits)
• Images (.jpg, .png, .gif)
• Wav audio files (.wav)
