How to stack QT Charts legend items vertical on bottom

[Saee1101]

I need the legend items stacked one above another (vertically).
When I do:

QtCharts::QChart *m_pieChart; //member variable
m_pieChart->legend()->setAlignment(Qt::AlignRight);

I get this:

And setting the alignment to bottom moves the legend to the bottom:

m_pieChart->legend()->setAlignment(Qt::AlignBottom);

BUT the legend items are not stacked vertically anymore!

How to move the legend to the bottom AND have them stacked vertically?

At a guess you cannot, else something would be documented or work. It will offer a limited set of possible layouts for you to choose from.

I see you have copied and pasted your question directly from stackoverflow, https://stackoverflow.com/questions/39243206/how-to-stack-qt-charts-legend-items-vertical-on-bottom, without mentioning this which is not helpful. That was asked 7 years ago. And did not attract any solutions. Suggestions included:

Looking in the sources, starting here, it doesn't seem possible without modifying Qt's code

[That is what I would have said.] And:

I solved it differently using QPieSlice::setLabelVisible(true) on all slices.

And:

Why don't you use the detachFromChart()? Look at this

Just saying "I have to do this" and "please help me" does not help. There is a reason why nobody posted a definite solution. So which of these did you try?

none . Actually, They aren't useful for me. I use :

  legend()->hide();

and use label.
thank you .
