CDF data variable "I" is used for X values instead of support variable Epoch, and axis is now properly labeled.

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 v2023a 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 (2023-02-23 r26948):

• Spectrogram binAverage and nearestNeighbor modes will use rank 0 BIN_PLUS and other codes to do a better job of establishing cadence.
• 2501:Corrections to CDF editor panel and completions.
• 2501:CDF with X= would show the wrong label for X.
• IDLSave X= and Y= parameters properly match the xunits parameter.
• IDLSave files support unsigned longs, as long as they don't use the high bit.
• 2506: recent change to CDAWeb to allow multiple variable selections didn't consider non-virtual variables. Thanks, Dante!
• 0048: Finally FFTPower translation is handled properly, where a second bug associated with translation was hiding in plain sight. Thanks, Keith!

Older Bugfixes (2023-02-21 r26937):

• 0048: FFTPower cadence changes are supported with no translation.
• 0048: correct where new code broke test for cadence change in FFTPower. Thanks, Keith!
• Corrections to directory listings with GitHubFileSystem.
• 2507: bug where ASCII reader would return data in different scheme with headers but no data.
• 0047: anchor type "plot" definition, underscore border type.
• 1696: automatically anchor annotation to canvas when plot is specified.
• fftPower has branch were factor of 4 was used where factor of 2 was appropriate. Thanks, Keith!
• 2506: CDAWeb reader didn't handle multi-variable reads when virtual variables are used. Thanks, Bob!
• corrections to HAPI server associated with non-ASCII unicode characters. Thanks, Bob!
• rfe795corrections to identifyContinuousBlocks. Thanks, Sadie!
• tweak where statistics are run on large datasets, which was causing pause before display. Run large dataset stats in the background.
• 2504: loading a .vap with duplicate IDs results in very weird behavior. Thanks, Bill!
• handle when getParam is called with the same parameter name twice, dialog is now resizable.
• "if(len(r_erg))" was included in simplified Jython script, causing runtime error. Thanks, Sadie!
• 2501: clean up the X and Y parts of the CDF editor dialog, so that only compatible Xs and Ys are offered. don't allow EwEw&X=EwEw, etc.
• rte_1865701214: strange and annoying RTE associated with setting the status bar text. Thanks, Bill!

Features:

• IDLSav supports ulongs, as long as the ulongs don't use the highest bit. Thanks, Cindy!

Less recent features:

• AutoplotDataServer has new usecache=false parameter. Thanks, Bob!
• AutoplotDataServer HAPI info response will set startDate and stopDate when they look reasonable, CDAWeb data source sets these based on all.xml. Thanks, Bob!
• Improvements to the Autoplot servlet, after seeing modern JavaScripts needed corrections to the code.
• 796: improve support for second timerange parameter. Thanks, Sadie!
