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
