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

Downloads

Stable releases or prereleases are available at the Qwt project page, or from the git repository.

Active development will happen in the develop branch supporting Qt >= 5.6 and relying on at least C++11. However all versions >= Qt 4.8 will actively be supported in the 6.x branches.
The popular multiaxes branch is derived from develop.

Installation

Qwt doesn't distribute binary packages, but today all major Linux distributors offer one. Note, that these packages often don't include the examples.

When no binary packages are available ( f.e. on Windows ) Qwt needs to be compiled and installed on the target system.
