Autoplot Application (#{tag})

Autoplot is used to make sparklines () for a prototype HAPI server.

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 7 is now required. Java 8 will be required sometime soon.

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 (2020-08-28 r25072):

• 2278: CDF slice1 keyword didn't work when Epoch16 timetags were used.

Older Bugfixes (2020-07-13 r24952):

• rte 1783311991: Check for null when identifying format of CDF file. Thanks, Alamo!
• rte 1783311991: CDFExceptions now keep track of initial cause to aid in support. Thanks, Alamo!
• simplifyScript checks for indeces which cannot be resolved d[r1] where r1 is not known.
• rte 761822764: Improve error message when X and Y arguments of CDF reader load variables of different lengths.
• ArgumentList utility assumed that default values for requireOneOf parameters where non-null.
• 2276: PngwalkTool inspect action now shows folders in local file chooser. Use Java 6 FileNameFileFilter everywhere, reducing code and making things consistent.
• don't replace existing NetCDF units with those found in the ISTP metadata, since the NetCDF ones are more likely to be correct.
• CreatePngWalk no longer allowed single URI to be used in place of .vap. Add uri= argument which is better anyway. Thanks, Warren!
• 2274: keep track of 401 exceptions so we ask for password again if incorrect password is entered. Thanks, Chris!
• add calendar button to mashup tool.
• 1728: set the value of the JComboBox directly, fixing old problem where black to white change was rejected. Thanks, Sadie!
• "add plot..." dialog didn't add to recent URIs list when only one URI was used.
• Java8 is now required in the Webstart JNLP file. (No Java8 code yet.)
• axis reference property didn't load properly from .vap files.

Features:

• suppress the legend when the plot width is less than 100 pixels.

Less recent features:

• 725: create pngwalk has option to remove pngs which don't contain data.
• bug 1687: introduce completions based on Java classes which could be imported and are imported when the completion proposal is accepted.
• improvements to the Java to Jython GUI, improvements to conversion (to support URI_Templates effort).
• 724: ISTP metadata allows for time location units like "seconds since 1970-01-01T00:00". Thanks, Steven!
• bundle command now has 5, 6, and 7 dataset versions. Thanks, Sadie!
• Annotation splitAnchor allows annotation X position to anchor to plot edge while Y anchors to data.

Known issues:

• see Source Forge
• Bugs often have a four-digit ID and can be reviewed with https://sourceforge.net/p/autoplot/bugs/<ID>/.
• Features typically have a three-digit ID and can be reviewed with https://sourceforge.net/p/autoplot/feature-requests/<ID>/.

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.
