Is there any open-source or free chart library for Qt? I only need XY charts, not bar charts or anything else.

QCustomPlot is a rather compact Qt widget for plotting, with the possibility of extension to your needs, under the GPL license. It has no further dependencies and is fully documented, including internal functions.

Check the QCustomPlot website.
