Autoplot Application (#{tag})

AVERAGE_TYPE metadata is introduced to properly handle interpolation of data which are angles or hours of day. See the script.

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 v2021a 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 (2022-06-13 r26680):

• URI vap+orbit:rbspa-pp&timerange=tr would be mangled in the editor if the timerange contained colons.
• Annotation had code which assumed the x axis units were not time location units.
• lblx extention triggered PDS source, but parts within the source were still checking for a .xml extension.
• 2456: progress bar left hanging after runtime error because RunLaterListener runtime error would block later listeners.
• 2455: misuse of iterator in Jython setItem sloppiness would result in hang. Thanks, Bill!

Older Bugfixes (2022-05-26 r26667):

• Corrections to FFTPower Translation code, which was broken after years of disuse. Thanks, Jolene!
• corrections to CdfSparseDataSet, which is needed to support FFTPower operation.
• 2454: correction to .jyds scripts, when script=xx keyword is used, PWD must be xx's location, not the data location.
• DisplayDataMouseModule shows the data precisely within the box, so that expected number of data points within a box can be confirmed.
• Correction to trim of JoinDataSet, which didn't consider that DEPEND_1 might be rank 2.
• 2453: CDF-reading code throws informative exception when blocks are greater than 2GB. Thanks, Kristoff!
• 2451: RENDER_TYPE=scatter is propagated through slice.
• 2451: back out change from Mar 21 (rev 26562), which broke existing functionality. Thanks, Jon N!
• remove where TODO items in BufferDataSet.append, supporting append of longs.
• 2449: case where append fails because timetags are different backing. Thanks, Ivar!
• HttpFileSystem getHeadMetadata had incorrect code when assembing URL for head request.
• PNGWalkTool had excessive synchronized block use, causing hang on Mac. Thanks, Sadie!
• Autoplot Server feature, where telnet from localhost can control Autoplot, once again allows imports. Thanks, Simon!

Features:

• 784 QDataSet AVERAGE_TYPE metadata introduced and used in interpolate.

Less recent features:

• Introduce ODL/STS data source. Thanks, Bill!
• 781 pngwalk tool "show only QC records" more options. Thanks, Sadie!
• Minimal specialColors property GUI added to assist in its use.

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.
