Hi Dan,
The ability to do uneven tick values is something that the SGPLOT, SGPANEL, and GTL support naturally. See pages 12-13 of this paper for more details: http://support.sas.com/resources/papers/proceedings09/324-2009.pdf. Let me know if you have any more questions about it.
I want to practise the uneven tick values shown in the figure 22 in your article, but where is dataset (physical end=eof?) you used in page 14, how to get the dataset?
or
I want to use SGPLOT to plot a uneven tick on x-axis in a proportional space but show all x value (see data below). how to do it?
x y
8 19
15 38.8
22 30.6
28 31
29 34.1
thanks!!
