Qt Widgets for Technical Applications
The Qwt library contains GUI Components and utility classes which
are primarily useful for programs with a technical background. Beside
a 2D plot widget it provides scales, sliders, dials, compasses,
thermometers, wheels and knobs to control or display values, arrays,
or ranges of type double.
