Plotting a Stock Chart with ScaleType <missing> WeekDay

I'm wondering if Apple will add a weekDay type ScaleType for plotting stock market charts.

The Date scaleType assumes that the weekend days (Saturday/Sunday) should be within the plotted data. But the typical stock market chart omits the weekends and holidays (non-market days) from the charts. Would Apple be interested in providing this new Chart Scaling Type. Or is there a way to extend the Charts Framework to allow this type of chart?

For Example: the X Axis might look like:

M T W T F M T W T F T W T F

Does anyone know how the other apps do this?

100  |
     |
 50  |
     |
  0  |_______________________
       Th  F  M  T W Th F

Maybe I don't know how to ask the right/best question. I want to plot price data with the latest price on the right and skipping weekend days (Sat. and Sunday).

Any ideas?
