QwtPlotDict is inherited by QwtPlot, so its destructor must be virtual.

i can add that many office application (word processors, spreadsheets etc), CAD systems (AutoCAD and clones, 3d StudioMax, blender) and so on uses wheelup as zoom in.

I want to attach a magnifier to each axisWidget in my plot (a QwtScaleWidget), and then enable only the relevant axis for that magnifier, like so:
for (unsigned int i = 0; i != QwtPlot::axisCnt; ++i)
{
QwtPlotMagnifier * mag = new QwtPlotMagnifier(plot,plot->axisWidget(i));
for (unsigned int j = 0; j != QwtPlot::axisCnt; ++j)
mag->setAxisEnabled( j...

I would vote for this too...
Lets have a look, in what software programs does WheelUp mean zoom in?
NO - Coin3d
YES - VTK
YES - Google-Maps (on the web)
YES - Google-Earth
VTK is the key one for me, so I'd prefer the behaviour to match.

WheelUp now will zoom in (as is it expected by me) and WheelDown then will zoom out.
I guess such behavior SHOULD be default.

0-1000 is the default range of a scale. Obviously your application attaches a zoomer to an uninitialized scale ( = missing replot ). And yes - assigning a scale explicitely ( f.e. by zooming ) disables autoscaling.

When i init the plot and setAxisAutoScale(QwtPlot::xBottom) and load some data to it - it works just fine. every update of the data with the following replot() show me the whole data range on the plot. But once i attached and enabled QwtPlotZoomer some annoying things happen. I do the zoom in with selecting the rectangle, it zooms ok. when i try to zoom one step back - it zooms not to the...

You can assign individual colors to any kind of labels in Qwt via the QwtText attributes. But IMHO synchronizing grid and tick label colors seems to be too special to have it in the Qwt library. Nevertheless it should be easy to implement it on the application side with Qwt 5.x.

Obviously qwt5 is the location, where you have installed the qwt headers, but this is nothing common. Instead of adding a path into your source code you have to add the directory as includes path to your compiler flags ( f.e in your .pro file )
