# Example (JKQTPlotter): Examples & Tutorials {#exampleProjectsTutorials}
|
|
This section assembles some simple examples of usage.
|
|
You can find more (complex) examples for the classes in this repository in the subfolder "test".
|
|
All test-projects are Qt-projects that use qmake to build. You can load them into QtCreator easily.
