XYPlot Library

XYPlot is a library written in Java which draws XY plots from any kind of data having X/Y values. The X values must not be equidistant but must continuously increase (e.g. time).
It separates data and graphical representation and is usually used by a business logic thread creating the data and a visualization running in an GUI thread. The library is available for SWT (c) Oracle based Java applications and for Android (c) Google. Special focus had been put on axis scaling and performance.
The graph can be inspected at runtime using things like zoom in and out, move left/right or change scaling.

The library has quite some history, it was first developed in 1990 for my lab work in experimental physics at the University in Tübingen/Germany (in Borland Pascal) and many years later been ported to Java.

In this repository you find the library and example applications for SWT and Android.

May be the library useful for whomever
