Placing multiple QwtText or QString at different heights on a QwtPlot
Hello everyone! Please help, I'm trying to place different inscriptions on a QwtPlot object. I can't find in the documentation how to place inscriptions using a QPoint object. I could only find how to place QwtText using Qt::AlignmentFlag, in which case it is impossible to place one inscription above another.
I am attaching an example of what I would like to receive.

This is a code snippet from the documentation that I used as a reference and tried to find similar methods to set text at the desired position in other classes (e.g. QwtPlotTextLabel, QwtText, QwtTextLabel, QwtPlotItem, QwtLegend, QwtLegendLabel etc.)

Re: Placing multiple QwtText or QString at different heights on a QwtPlot
You can control the position using the margin property of the item and the alignment ( QwtText::renderFlags ) of the text.
If this is not good enough you can also overload QwtPlotTextLabel::textRect() and return the bounding rectangle for the text being calculated from whatever you like.
HTH,
Uwe

Start with the QwtPlotMarker code—tweak X/Y values to fit your plot. If you share your axis ranges or more code, I can fine-tune it. What’s your Qwt version (6.1.x, 6.2)? And what’s the plot for—data viz, science, art?
