Magnification example

Hi,

LibreOffice displays charts the same way as its competitors: You can specify
the data range, the X/Y scale and that's it. You can't interact with your
diagram in order for instance to easily zoom in some areas where data are
cluttered.

This ticket proposes an enhancement ideas in order to bring added values to
LibreOffice compared to its competitors: Having the ability to investigate into
a chart in order to have chart details without tweaking chart settings or even
use bug 138509 enhancement proposal.

By clicking a button the cursor would transfomr to a magnify glass which, when
hovering on top the graph, would display local details. See example attached.
This would be very usefull when lot of data are cluttered in a graph and one
want to quickly highlights some facts.

By "magnifying" I don't mean "stretch some raster bitmap to have a pixelized
result" but have a clear local rendering of the area (as when one zoom on
vectorial images).

Additional control proposal:
- Playing with the mouse wheel would change magnifying factor.
- Playing with the mouse wheel while pressing CTRL would change magnifying
glass radius

Nothing would be saved in graph settings.
