Autoplot Application (#{tag})

jnlp WebStart

Single-Jar

exe

Revisiting the Cookbook's LSpec routine, and a new version is found at GitHub.

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 (2022-05-26 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!

Older Bugfixes (2022-04-29 r26638):

• improve feedback when "{" is seen in the middle of a HAPI data response, which is an easy mistake for servers to make.
• make it much more likely that the mashup tool result in synchronize data sets to be set.
• new specialColors code didn't handle missing data and would cause runtime error.
• 2445: plot makes a copy of the data for defense and for performance.
• check list of renderers for transitional case, where the returned list would be one element too long with a null in the last element.
• remove "Here DELTA" debug message in SubsetDataSet.
• Jython symbol "map" is included in list of quickly executed routines, to support use in generating getParam GUIs.
• suppress warning about SCALEMIN and SCALEMAX when they are NaN, NaN, and just ignore them.
• 2444: Run Batch would not create a new interpretter for each run, so information could leak from one run to another.
• Re-run single job of batch would run on event thread, hiding feedback and locking application.

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.

Less recent features:

• new series icons reflect linethickness.
• allow .vap file in pngwalk using version numbers to check for the versioned .vap file as well.
• allow space or comma to be entered in single field of inline data dialog to speed up data entry in some cases.
• spectrogram icon reflects colorbar used.
• new series icons reflect symbolSize
• completions on plot command now supports completing keyword parameters.
• crossProduct function added.
• Color Scatter mode now has icon.

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.
