Autoplot Application (#{tag})

New CDF editor droplist allows searching metadata for strings like "Flux." Happy Autumn!

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 v2019a branch. This is an update to the production version containing bugfixes and minor new features. Java 7 is now required. Java 8 will be required sometime soon.

Run with 4GB of memory (64-bit Java only): autoplot_4GB.jnlp

Single-jar version, autoplot.jar, can be run without network access and from the command line.

Mac DMG Release is available.

Bugfixes (2019-09-23 r24144):

Older Bugfixes:

• 1359: refactor scan next/scan previous code to allow for testing.
• bug in rfe445, where Masafumi pointed out that data which once ranged now has a runtime error because of Inf's. Thanks, Masafumi!

• rte_1569838156: catch IllegalArgumentException when Units.min is encountered.
• rte 0726091791: reference setting on zaxis (colorbar) would result in NullPointerException.
• org.autoplot preference should be used before org.virbo.autoplot copy.
• 2175: loading .vap shouldn't change the scientist's color and font preferences after reset.
• 2194: handle case where StreamDescriptor no longer recognizes a packet because the id has been recycled, dropping a record.
• QStream toAscii would use formatter which didn't support doubles with large negative exponents, showing "0"...
• das2server TCA (ephemeris) URIs now load based on needed resolution.
• findbugs fixes, where difficult thread warning IS2_INCONSISTENT_SYNC is resolved.
• "Check URI" monitor wasn't centered on the application.
• error bar thickness should be the same as the line thickness.
• rte 1858002116: check for null from "where" list in NetCDF, HDF and CDF dialogs. Thanks WRF!
• continue round of FindBugs cleanup. (Yay, below 100!)
• 2188: makeCanonical corrects double-slashes (//) fixing the bug.
• 2189: corrections to clipping in DasPlot, a bug seen with scrollbars on Linux. Thanks, Ivar!!
• remove class DatumRangeUtilOld, which is not used.

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!
