Show a scale for the same axis on both sides of the plotcanvas

[SimonSchmeisser]

Hi There,

I would like to show a scale for the y Axis on the left as well as the right side of the plot canvas. They should display exactly the same range etc.

I guess I could add a QwtScaleWidget and work out something with this, but then I guess I have to do the layout stuff myself?

Thanks a lot
Simon

I would like to show a scale for the y Axis on the left as well as the right side of the plot canvas.

plot->enableAxis( QwtPlot::yRight );

They should display exactly the same range etc.

This depends on how you set your QwtPlot::Left axis.

If you don't assign it manually you can connect to the QwtScaleWidget::scaleDivChanged() signal and synchronize the right axis from the left one ( use QwtPlot::setAxisScaleDiv() ).
