The software package I co-develop at work is dependent on Qt 4.8, but we plan 
to move to Qt 5 when we have time/funding. We currently depend on a third-party 
plotting package for our 2D data visualization, but we'd like to be able to use 
QtCharts when we upgrade.

Some of our data sets are time-dependent and are often extrapolated hundreds or 
thousands of years in the future. As such, a logarithmic time scale would be 
quite useful, if not necessary to view the data in a truly meaningful manner.

Can anyone provide guidance on properly extending QDateTimeAxis (, 
QLogValueAxis, or QAbstractAxis) to provide a logarithmic time scale as I've 
described?
