axis tics at specific values

["Carlos \"Guâno\" Grohmann" <carlos grohmann gmail com>]

Hello all,
first post to the list. I usually use R to my stats/graphics, but
decided to give Gnumeric a try, and so far I'm must say I loving it!
Easy, fast, powerful.
But I have a problem..
I want the tics of the X-axis of a plot to be at specific values
(3,5,7,9,11,13,15,17,19,21,31,51)
and I found no way of doing it.

is it possible? (seems to be pretty standard feature for spreadsheets..)

And just a wish to add, can we have more symbols to plot? there's not
even a circle...

thanks all

Carlos
