Bug where invalid time ranges could get into history is fixed.

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, and run off of ci-pw build server: autoplot_1GB.jnlp

Bugfixes (2021-10-15 r26125):

• 2401: eq with nominal units produces runtime error. This is now supported. Thanks, Ivar!
• 2400: Don't paint opposite axis if there is a different axis there already.
• 2195: LANL NN render mode didn't work when tags were monotonic decreasing.
• 2134: support for negative step, useful in scripts to flip over arrays.
• annotations dialogs have link to documentation.
• 1659: in CDAWeb when dataset does not have master file, subTaskMonitor.finished was called twice.
• 2400: white-line-on-white-plot still draws to support when a contrasting color is under the plot. Thanks, Ali!
• 2400: manual ticks ignored the minor ticks in "1,5/2,3,4,6,7,8,9". Thanks, Ali!
• 2399: invalid timerange got into history causing confusion.
• correct misspelling of indices in Ops Javadoc. Thanks, Ivar!
• 2398: monotonicSubset sets MONOTONIC to True, working around the problem Kristoff saw.
• 2397: New Javadoc, still unpublished, supports extra characters like "Returns e^x -1."
• 2394: IDL reader properly reads in array of strings and structure data following a string array. Thanks, Lindsay!
• IDL reader support completions are corrected so automatic GUI is fixed.
• 2391: Jython dataset setItem was overly cautious in its check for units, seriously degrading performance. Thanks, Bill!
• correction to where datum having units is assigned to dimensionless dataset in Jython.
• Jython scripts encoded in UTF-8 with non-breaking spaces are handled now by replacing with normal spaces. Thanks, Cindy!
• 1028: ds[x,y,z] where x y and z are rank 1 list of indices didn't allow negative indices.
• 2390: correction to logic for copy plot elements down, which would break in some cases. Thanks, Allison!
• layout tab list of plot elements wouldn't repaint when the legend label was changed.
• revert log/lin ticks logic, which is needing more time than available.
• "regex mode" for ASCII table parser would clear the units, limiting capabilities.
• Corrections to add plots and fix layout. Now only plots attached to the marginColumn are used for the layout.

Older Bugfixes (2021-07-06 r25854):

• 2386: case where SortDataSet didn't support empty list to index empty dataset.
• default setting of "add plots" dialog should be "below current" to minimize changes.
• 2385: question marks in all.xml meant multiple things weren't plottable.
• Ivar pointed out that draw grid caused lineplots to have transparency to them. Thanks Ivar!
• Remove temporarily use http for runtime errors, not https, since jfaden.net https certificate is fixed.
• 2383: exception reports and about menu show launch mechanism used.
• "fix layout" will also remove gaps horizontally when multiple columns are used. Thanks, Ivar!
• 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.
• Ephemeris lines are limited to 32 lines, was 10. Thanks, James!
• 2378: add setDepend0Cadence, setDepend1Cadence, and setValidRange so these are accessible in scripts. Thanks, Sadie!
• 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.

Features:

• plot.colorbarColumnPosition property added, so that the colorbar can be pushed over to make room for a second axis.
• Text strings can contain <u> for underlining text.
• NetCDF provides completions for x= and y= controls.
• Jython editor has beginnings of annotations for differences.
• GitCommand introduced to wrap calls to command line git, and native Java git is coming.
• 754: aggregation can handle in-context timetags where just hours-since-midnight is in file. Thanks, Sadie!
• 727: private GitLabs/GitHub projects can be used with ro_cache.txt mechanism. Thanks, Sadie!
• Meyers diff introduced to support showing changes between two text files and eventually data sets, using com.github.difflib.
• 456: external changes in script are automatically loaded without confirming this with the scientist.
• "AP> print 'hello'" works at the command line, to support copy-n-paste from references which contain "AP>" prompt.
• join(extent(),extent()) is properly formatted as two ranges.
• Introduce Units.us2020, for use when microsecond precision is needed around 2020. Thanks, Kristoff!
• IDLSave reader uses %d format for integer data.
• IDLSave reader corrections to read array of strings, automatically detect ISO8601 data.
• more accepting of HAPI servers under development, issuing warnings to help find problems.
• applyIndexAllLists extracted from Jython code and made available to Java codes as well.
• filter editor panel added for expandToFillGaps. Thanks Bill!
• 18: new logic for log ticks when ~1 cycle is showing.
• "About Autoplot" screen shows the release number, not the marginally useful v2021. Thanks Bill!

Less recent features:

• plots have new legendFontSize property. Thanks, Ryan and Wouter!
• 753: leave fscache .listing files in place to support offline mode and file availability.
• eventsDiff function introduced to show differences in lists and inserts, deletes, and changes. Thanks, Ivar!
• "add plots" dialog now allows stack of plots to be added to the right or left. Thanks, Ivar!
• introduce triangulate routine to expose this internal functionality.
• 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/

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!
