Autoplot Application (#{tag})

Single-Jar

On 32-bit systems, use the single-jar release and a 32-bit version of Java. These systems will be limited to 1GB of memory. Other Autoplot versions are available for about a year.

Fun data from new HAPI server.

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 one uniform data model. Data are then displayed by determining the rendering method and axis ranges to provide a useful display with interactive axes and mouse actions. The data can then be further processed with other operations like smooth and FFT, and Jython scripting provides a capable programming environment.

This is the Autoplot v2026a branch. This is an update to the production version containing bugfixes and minor new features. Java 8 is required.

Autoplot's development is guided by feedback from those using it. Thanks for your feedback!

Bugfixes (2026-08-18):

• rte 0188745986: runtime error with full reset and two added tabs caused index out of bounds error.
• 2880: Display warning when CDF variable name is not proper Python variable name or will cause problems.
• 2845: improvements to Jython completions.

Older Bugfixes (2026-08-15):

• 2872: clear state within AsciiTableDataSource which would have the effect of the second call to getDataSet returning a different dataset. Thanks, Ivar!
• 2877: Support FFTPower of X component. Thanks, Dave!
• 2876: PWD in remote .jyds scripts was the download directory, not the https:// site, so adjacent calibration table could not be loaded.
• rte 1817056005: QStream yrange was interpreted with Z units for spectrograms. Thanks, Larry!
• 2870: use mapped memory to access data in IDLSave files.
• 2864: correct read of two-element complex array.
• 2827: /tmp/data/data.$s?avail=T properly triggers TimeSeriesBrowse.
• 2860: add escape key to runtime error dialog
• 2863: repeat runs of script without reset and overplotOf would keep adding plot elements. (Code is now enabled)
• 2862: support "print ds[0,-1]" in Jython
• 2864: improve names automatically picked on export to IDLSave.
• incorrect check for fill (Nan==Nan is always false) broke fill value used for times in JUNO/JADE PDS3.
• 2863: repeat runs of script without reset and overplotOf would keep adding plot elements.
• IDLSav of CDF_TT2000 is detected when name contains "epoch". Thanks, Dave!

Features:

• 883: Select time range by Orbits allows simple search.

Less recent features:

• 2873: vap+inline URIs with one getDataSet call now support "replace file" action. Thanks, Ivar!
• 879: add completions for each enum of getParam, also from examples.
• 2867: add routines for realPart and imaginaryPart.
• 877: Allow "https : //..." to be used in the address bar, so that Autoplot URIs are left alone in Outlook.
