GtkDatabox is a widget for the Gtk+-library designed to display large
amounts of numerical data fast and easy. One or more data sets of
thousands of data points (X and Y coordinate) may be displayed and
updated in split seconds. The widget is therfore used in many scientific
and private projects that need to show quickly changing data "live".

GtkDatabox offers the ability to zoom into and out of the data and to
navigate through your data by scrolling. In addition to rulers and
a simple coordinate cross, GtkDatabox now also allows you to add one
(or even more) configurable grids like on an oscilloscope.
