Formatter= stringFormat::create(),% ??? How to set a format flag in Formatter for vertical text here ???G:drawString(axisLabel,Font,CtrlRectF,Formatter,Brush),

I can get the job done in a kludgy way by interleaving carriage returns between the characters of the string, but it would be more robust to use stringFormat.
What happened when I was trying to find the constant (stringFormatFlagsDirectionVertical) was that I wrongly assumed I would find it in the pfc\gui directory tree and searched files there for the substring "vertical" using Ctrl-Shift-F.
The constant is defined in pfc\windowsApi\gdiplus_api folder so I didn't search the proper directory tree!
Moral to the story: Search the entire pfc directory tree when you don't find what you seek.
