QBarSet; SetLabelColor & SetLabelFont don't work. Qt failure?

[Josz]

Hello community, (I Use Qt 5.11.2 on Windows with msvc15)

I would like to adjust the Font style and the size in aQBarSet.
From the beginning the simplest settings don't work

I tried the next code:

set2 = new QBarSet("MyText", this);
 QFont myDesiredText = QString("my_Desired_Text");
 myDesiredText.setPointSize(2);
 myDesiredText.setBold(1);
 set2->setLabel("MySecondText");            //work
 set2->setLabelColor(Qt::red);              //don't work
 set2->setLabelFont(myDesiredText);         //don't work

The Label shoes at the end "MySecond text".

I think that's an issue in Qt or perhaps I did't make the things fine.
Please, could somebody show me how to configure the font type and its size in a QBarset?
(I googled, but not successfully)

thanks in advance.

Try to change the sequence and use use larger point size for a start e.g.:

set2 = new QBarSet("MyText", this);
 QFont myDesiredText = QString("my_Desired_Text");
 myDesiredText.setPointSize(12);
 myDesiredText.setBold(true);
 set2->setLabelColor(Qt::red);       
 set2->setLabelFont(myDesiredText);
 set2->setLabel("MySecondText");

@koahnig Thank you very much

Sadly didn't work.

I tried:

  set2 = new QBarSet("MyText", this);
  QFont myDesiredText = QString("my_Desired_Text");
  myDesiredText.setPointSize(12);
  myDesiredText.setBold(true);
  set2->setLabelColor(Qt::red);
  set2->setLabelFont(myDesiredText);

and the label shows "MyText" of the first line :-(

@Josz
I guess that you need at least the statement

set2->setLabel("MySecondText"); 

at the end.

@Josz said in QBarSet; SetLabelColor & SetLabelFont don't work. Qt failure?:

QFont myDesiredText = QString("my_Desired_Text");

what do you expect that this line does?
Is there a font named my_Desired_Text?!

Also you may want to try setLabelBrush(Qt::red)

@raven-worx Thanks raven

I tried

  set2 = new QBarSet("MyText", this);
  QFont *font = new QFont("Helvetica",13,13,true);
  //font->setPixelSize(2);
  set2->setLabelFont(*font);
  set2->setLabelBrush(Qt::red);
  set2->setLabel("MySecondText");

don't works either :-(

I found a solution. Not the expected, for this reason I will not mark it as solved, but works

    QString thresholdText = "Threshold " + QString::number(threshold);
    set2->setLabel("<b><font size=4 face = 'Nina'>"+thresholdText+"</font></b>");
