The "Length" mouse action is used to measure the distance in X (18.0 hr) and Y (-114.7 nT). Right-click on the plot to select the mouse action.

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 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: autoplot_1GB.jnlp

Bugfixes (2021-08-27 r25972):

• Temporarily use http for runtime errors, not https, since jfaden.net https certificate is broken.
• triple quoted strings would always move the lastLine pointer, sometimes preventing the GUI creation from the address bar.
• Emphemeris lines are limited to 32 lines, was 10.
• 2378: add setDepend0Cadence, setDepend1Cadence, and setValidRange so these are accessible in scripts.
• round of Findbugs cleanup to get down to 80 flagged issues.
• 2380: Correction to append, used with aggregation, when "where" is used with rank 2 CDF datasets. Thanks, Andrei!
• Safety check on putProperty UNITS on FDataSet for TimeLocationUnits didn't consider that None (null) is a valid setting. Thanks, Sadie!
• Vertical Spectrogram Averager was broken for the rank 2 (Z[X,Y]) case.

Older Bugfixes (2021-07-06 r25854):

• BinaryDataSource throws a more actionable error message when it is instructed to read past the end of a file.
• .sps and .spd Jython extensions moved from server at U. Iowa to GitHub
• timerange completions corrected for CDAWeb source, to support scripting.
• GitHubFileSystem supports listings from GitHub, before you could only access files if the name was known already. GitLabs still needs work.
• return type of the function call was sometimes mis-reported in Jython completions, as in convertUnitsTo.
• 2376: some of the set item methods in Jython mishandled the units. Thanks, Ivar!
• Unpushed change which caused a bug in the ASCII reader was pushed unknowingly and was never tested in last devel release.
• 2375: new code to show "add tool" checkbox on script parameters tab broke GUI in one case.
• 2374: StaticCodeAnalysis.showUsage corrects incorrect offsets when cos((myvar)) is used, where the double parens show bug in Jython. Thanks, Sadie!
• Binary data source reportOffset uses T and F now, to match other data sources.
• add @see flattenWaveform to synchronizeNN documentation, since the scientist would typically need to flatten the data first. Thanks, Sadie!
• Binary data source can read huge binary files (>2GB), though only 2GB at a time. Thanks, Darrelle!
• Initial Bookmarks GUI would allow the description and title to be modified, even though no bookmark was selected, causing confusion.
• Data Mash-up tool supports "None" as a parameter, allowing "fftPower" function to be used. Thanks, Andrei!
• 2364: code which closed Autoplot back-end server removed, so that multiple commands can be sent.
• 2367: guess time format mistook four-character "time" for $H$M field. Thanks, Sadie!
• if series color scatter data zunits were not convertible to colorbar units, the data was not displayed and no warning message was printed. Thanks, Sadie!
• 2369: ASCII file reader treats non-breaking spaces, from copying data in email, as whitespace. Thanks, Sadie!

Features:

• new JNLP file works on both 32 bit and 64 bit machines, giving 4 GB to 64 bit machines.
• PDS4 source has experimental logic for resolving dependencies between dependent and independent parameters.
• OperationsProcessor.process(ds,str) introduced to correct order of operands (dataset should come first, conventionally).
• sps and spd reading scripts now come from https://github.com/autoplot/scripts/blob/master/formats/sps/

Less recent features:

• DataSetIterator now has getRank0Value and putRank0Value (as well as double access), making it easier to write correct code.
• Custom Jython editor actions now appear one level higher.
• 17: Support for <b> for bold (</b> to turn off) and <i> for italics in labels. Thanks, Chris!
• add plots with multiple rows finally supports replace current. Thanks, Ivar!
• Introduce dom.controller.selectedPlots property. See joinPlots.jy for example use.
• Introduce new qubeSubset which will throw out data until the non-qube can be represented as a qube, to assist with the Das2Server. Thanks, Terry!
• 1: use "run" where "execute" is unnecessarily used.

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.
