Two questions:
1: how to operate grid lines, such as add minor grid line, add only x or y grid lines?
2. can I move the position of x or y axis title?

1: how to operate grid lines, such as add minor grid line, add only x or y grid lines?

On the Options>Extents/Intervals/Size dialog you can add minor grid lines in either direction by setting the "Minor grid/tick divisions" entry to some value greater than 1. You cannot have grid lines in only one direction, if that's what you're asking.

2. can I move the position of x or y axis title?

You can shift it up/down by adding line feeds, but that's it as far as positioning goes. To move a title line up by 2 lines, for example, use "Title line\n\n".

If you need more control I suggest using a Note instead. Notes can be positioned anywhere.

I have a question about axes.
If I use Options > Grid Lines or Box > Axes Only, is there a way to get rid of the extra little line that sticks out on the axes? Below is an example...

No, you can't. But now that you've asked I think most people who turn the arrowheads off would want this as the default behavior. I'll change this for the next release... of course doing that will lead to the next request concerning extending those lines

Thanks as always!

I didn't mention it on the Revisions page, but this is taken care of in last night's (Jul 17) update.

Yeah, I gave it a whirl as soon as the update came through last night. Thanks!
