Do you think is it possible to build a doughnut chart in QM?
See my answers below, pls.
Tahir, thank you for your interest in my implementation of Doughnut charts in the QM. At your request, I am attaching a QM model with step-by-step construction of Doughnut charts. I hope everything is clear in that model. Otherwise, I am ready to answer here or by e-mail: firstname.lastname@example.org (you can write Russian).
