Y-Axis Textdirection

[oldman]

Hallo,
i have a 2D-Plot with two y-axis and would like to have the axis-text in the same direction for both axis'.
I thought to do this with method:

plot->setAxisLabelRotation (QwtPlot::yRight, rotationInDegree);

But this didn't work. I also tried it with different values for rotationInDegree.
Whats the problem?

That's my code until now:

plot = new Plot();
plot->enableAxis(QwtPlot::yRight, true);

QFont axisTextFont;
axisTextFont.setBold(true);
axisTextFont.setPixelSize(14);

QwtText rightAxisText(QString("rechts"));
rightAxisText.setColor(Qt::red);
rightAxisText.setFont(axisTextFont);

plot->setAxisTitle(QwtPlot::yRight, rightAxisText);
plot->setAxisLabelRotation (QwtPlot::yRight, -180.0);

plot->replot();


thanks a lot for your help

QwtPlot::setAxisLabelRotation is for the tick labels only. Instead you have to do:

plot->axisWidget( QwtPlot::yRight )->setLayoutFlag(QwtScaleWidget::TitleInverted, false);

plot->axisWidget( QwtPlot::yRight )->setLayoutFlag(QwtScaleWidget::TitleInverted, false);

To copy to clipboard, switch view to plain text mode

Thank you Uwe for this information,
but sorry i missed yesterday to mention that i use qwt version 5.1.1.
In this version the method setLayoutFlag don't exist.

So exist there another possibility??


The program is not written by me so it is not easy to switch to a newer version of qwt.

No - all you can do is to patch your own version of Qwt.

Hi Uwe,
i switch to version 6.0.0-rc5.

Wasn't difficult.
