Using qwt from https://sourceforge.net/p/qwt/git/ci/qwt-multiaxes/tree/ Applied the following changes to qwt 6.3: * Added QwtZone to qwt_plot_curve.cpp * Disabled the emitting of Layout Requests on geometry changes of QwtScaleWidget - without this, CPU utilization was up to 100% on one core Fixes #4495
