QwtPlot - Changing Title fonts

[Eos Pengwern]

The size is an attribute of a QFont. How to assign a QFont is explained above.

But in that case, setting the plot font to the same font as the rest of the widget, for example by:

myPlot-> axisTitle(QwtPlot::xBottom).setFont(this -> font());

myPlot-> axisTitle(QwtPlot::xBottom).setFont(this -> font());

To copy to clipboard, switch view to plain text mode 

... should result in the font size, as well as the font style, being synchronised. My axes titles are still in a much bigger font than everything else, however.

What am I missing?

QwtPlot::axisTitle() is a getter and it doesn't make much sense to assign something to an object, that is returned by value.

Better do something like this:

QwtText title("BlaBla");
title.setFont(QFont("Helvetica", 20));
plot->setAxisTitle(QwtPlot::yLeft, title);

QwtText title("BlaBla");
title.setFont(QFont("Helvetica", 20));
plot->setAxisTitle(QwtPlot::yLeft, title);

To copy to clipboard, switch view to plain text mode

Fantastic, that works! Thank you very much.

I've an additional question:
how it is possible to change a plot legend font size? and, if possible, the dash size indicating the curve color?
thanks

Isn't that a different question?

Ressurecting so old thread isn't the best idea.
Just create new thread so others can find it as well instead of using semi-related subject.

Sorry,
I've done it only beacause I've seen that somebody else did it before me (2007-2009)
thanks for the advice.
