Re: x axis Major Tick Marks

Hello,

    The "res@tmXBPrecision = 4" is to output four-digit numbers. Without
this, x axis would have real numbers. But removing the
"res@tmXBPrecision = 4" did make the warning disappear.

    Tingting's commands output real numbers on x axis. With "
res@tmXBPrecision = 4" there would be duplicate years on x axis.

    Anyway, thank you very much,
