Autoplot Application (#{tag})

Autoplot is used to study internet download speeds.

Autoplot allows plotting of data from many data sources, including remote CDF files and OpenDAP 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 v2020a branch. This is an update to the production version containing bugfixes and minor new features. Java 8 is now required.

Run with 4GB of memory (64-bit Java only): autoplot_4GB.jnlp

Single-jar version, autoplot.jar, can be run without network access and from the command line.

Mac DMG Release is available.

Bugfixes (2020-12-29 r25415):

• improve transparency of local files used with ro_cache.txt, where local files can be used to resolve remote files.
• 1310: --sandbox mode with "open vap file" now works on a Mac, which checked to see if the read-only folder was writable.
• 1687: scripts with first line was a multi-line setScriptDescription couldn't be run from the address bar.
• 1310: --sandbox command line option limits writes to ~/AUTOPLOT_DATA and /tmp.
• 2309: correction to DataPointRecorder when reading a file. Thanks, Sadie!
• always support "~/..." as a shortcut for home directory.
• 2309: correction to DataPointRecorder units change when emptied. Thanks, Ivar!
• 1779: copy/paste plot is more aggressive about trying to bind the pasted plot's x-axis to the timerange. Thanks, Bill!

Older Bugfixes (2020-12-02 r25360):

• PNGWalkTool data-to-pixel transform had discontinuity at axis edge. Now there is an output limit of -10000 to 10000, which is consistent with the DasAxis object.
• Datums backed by Long but not Units.cdfTT2000 would cause runtime error when printed.
• 2305: doAxisDimensionsChange returned false, causing reset which resulted in using old dataset for axis labels.
• 1636: corrections to Jython code refactoring (simplification of script to get params or for completions) after it was discovered that test server was failing to notify. Simplification of codes.
• 2304: Another round of localization checks is needed, das2server check. Thanks, Corentin!
• 2303: histogram filter didn't properly handle decimal arguments.
• 2302: File->Open Vap file breaks when remote URI is in address bar. Thanks, Ivar!
• rte_1637324209: occasional runtime error when loading vap, associated with new error bar controls. Thanks, Bill!
• 2300: script plot command toggles through invalid intermediate state, experiments with reset.
• multi-line string used with setScriptDescription would cause parse error.
• In Mathematica to Jython, properly handle "2754 2^(2/3)"
• medianFilter would fail if there was too much fill data. Thanks, Kristoff!

Features:

• rebundle command allows subsetting and resorting of bundle datasets.
• support datumRange(5,10) in scripts. Thanks, Ivar!
• events bar supports lineStyle and lineThick properties, new opaque property disables default transparency. Thanks, Ali!
• getFile can have null passed in for the monitor, when the developer knows the load will be quick.

Less recent features:

• rfe501: allow custom mouse event handler and topDecorator to be added to the PNGWalkTool.
• rfe704: setScriptDescription can have a clickable link.
• referenceX and referenceY allow list of datums to point at or mark with symbol in annotations.
• anchorBackground property allows regions to be highlighted in annotations.
• rfe734: bundle URI keyword for ASCII files should return bundle descriptor
• add annotations list on the layout tab. Thanks, Kristoff!
• rfe363: check version of Javadoc when deciding how to create link.
• rfe363: finally "addToSearchPath"'s Javadoc argument is used for Javadoc completions. (To be shown at 2020 AGU.)
• rfe363: first batch of new icons showing Java static method vs instance method, properly filter by context.

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 autoplot.org will run this version. Feedback on the function and quality of this release is greatly appreciated!

Data is input from:

• ASCII files (.dat,.txt)
• CSV files (.csv)
• Binary files (.bin)
• CDF files(.cdf)
• Excel spread sheets (.xls)
• das2Streams (.d2s or .das2Stream)
• ViRBO's TSDS server
• CDAWeb data server (vap+cdaweb:)
• das2servers (vap+das2server:)
• QStreams (.qds), QDataSet on a das2Stream
• Plasma Wave Group das2 Server
• NetCDF files (.nc,.ncml)
• HDF5 files (.h5,.hdf5)
• DODs servers (.dds)
• Cluster Exchange Format files (.cef)
• Fits Format Files
• Images (.jpg, .png, .gif)
• Wav audio files (.wav)

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.
