QCustomPlot is a Qt C++ widget for 2D plotting and data visualization, licensed under the GPL. It focuses on making good looking, publication quality 2D plots, graphs and charts and also has high performance for realtime visualization applications.

QCustomPlot can export to various formats such as vectorized PDF files and rasterized images like PNG, JPG and BMP. All outputs look identical and the generated PDF files can be imported and edited by vector editors like Inkscape, without trouble. So QCustomPlot is useful for both displaying of realtime data inside the application as well as producing high quality plots for other media.
