Java Time Series Library

 Tuesday, June 3, 2014

I have been working on a Java (7) timeseries library for a while now and I'm pondering releasing it (with documentation) into the free domain (under LGPL) . The library allows for easy data loading from flat files or a database and provides a fairly significant set of mathematical methods (incremental and vector based). It also supports performance calculations and visualization (built upon the JFreeCharts library). Before I do so I though I'd take a straw poll to see how many people would have an interest if it were available.

Richard,

Good work, it would help a lot, especially the connection to a charting library.

Richard, it would be nice if you manage to sort hdf files and Java. This is still a bit painful. Also make sure you support export into standard Java script formats to talk to highcharts and modern JavaScrpt charting libs. JFreeCharts is so old school. Just post some stuff on Github and see where it takes you. I have actually a tiny library for time series and Java online. see https://github.com/tschm/ts-timeseries

I've been using jfreechart for charting with my algorithm. Also use matplotlib with python for 3d and other timeseries data massaging. One problem that I've been struggling with for some time is to programmatically determine bottoms and tops in a time series. I've tried to use sliding window/Huang-Hilbert transform but wasn't satisfied. Does the library you offer have anything similar to Huang transform ? Also some other like area under curve using simpsons and/or trapezium ? tia

I would love to have access to such a library. I would even be interested in contributing code back to it, if it were available under a GPL or LGPL license.
