I would rather make the modifier OS-dependent.
In other words, META for macOS, and CTRL for the rest.

Just in case, ctrl+click means "right click" in macOS

I have pushed a commit to adding the os dependent code using OSXSupport.isOSX().

double pos = (double)(getHorizontalScrollBar().getValue()) / (double)(chart.getWidth());
if (e.getWheelRotation() > 0 && getScaleFactor() < 100) {
setScaleFactor((getScaleFactor()*1.2));
