Re: How to set number (Frequency) of minor ticks for xy plot

Mark,

There are two situations when setting minor ticks. I will take the XB
axis as an example

First, when tmXBMode = "Explicit", you have to explicitly prescribe
the position of minor ticks by tmXBMinorValues.
   res@tmXBMode = "Explicit"
   res@tmXBValues = ispan(0, 23, 12)
   res@tmXBMinorValues = ispan(0, 23, 4) ; set 2 minor ticks between
two major ticks

Second, when tmXBMode is not set, you can use tmXBMinorPerMajor to
directly set the frequency of minor ticks, like res@tmXBMinorPerMajor
= 2.

Hope this helpful.

Regards,

Xianxiang
