multiple left axes in QwtPlot still possible? -solved

Hi
I found this: https://www.qtcentre.org/threads/690...Plot-multiaxes
which suggests there is a file qwt_axis_id.h
and you can define multiple left and right axes
QwtAxisId axisY1(QwtPlot::yLeft,0);
QwtAxisId axisY2(QwtPlot::yLeft,1);
This post refers also to https://www.developpez.net/forums/d1...lusieurs-axes/
for another example
which uses QGraph->setYAxis(QwtAxisId(QwtAxis::yLeft, 0));

however I cannot find any reference to QwtAxisId in version 6.1.6 ? I hope this feature still exists?
(my install is package within msys2)
Thanks
Victor

EDIT: the solution is in this branch: http://svn.code.sf.net/p/qwt/code/br...6.1-multiaxes/

The multiaxes branch can be found in the officiall qwt SVN ( soon git ) repositories.

On github you find several clones from users that are in no way related to the Qwt development. AFAIR this one was made to build Qwt with cmake.
Of course you can't expect any support for code from nonofficial sites.
