    Default Force numbers to display in scientific notation

    Is it possible to force the numbering in Qwt to be in scientific notation?

    My main problem is that I'm dealing with scales around 1e-10, and QwtPlotZoomer displays the mouse tracker as 0.0000, 0.0000.

    Can I force those numbers to display something like 1.50443e-10? I couldn't find anything in the documentation.

    Is this something I would have to define myself in Qt?

    Thanks,
    Dane Larsen

    Overload QwtPlotZoomer::trackerText.

    I figured that would be the case. Thanks for confirming it!
