Subject: Irregular axes under SAS/GRAPH
Content-Type: text/plain; charset="us-ascii"
I've developed a method, am looking for a better (or built-in) way.
I am plotting data which typically falls in a narrow range, but has
periodic outliers. Range might be -3.2 to 3.2, outliers might be in the
positive or negative thousands. Using regular linear (e.g.: -4 to 4 by 1
) axes, I have a choice of either resolving detail of typical data, or
showing all outlier data, but not both.
The solution developed is to generate an axis order description with
variable scaling -- regular sequential through typical data values, and
irregular (typically logarithmic) through outlier values (e.g.: -10000,
-100, -4, -3, ... 3, 4, 100, 10000) -- which can be done fairly easily,
and represents both the detail and the extreme values (and has a certain
Tufte-esque feel to it, for those familiar with his concepts of
The GPLOT procedure acknowledges this by printing a warning "axis
intervals are not evenly spaced" -- well, that's what I'd requested, no?
I don't like unnecessary warnings in my log (I tend to treat warnings as
errors, however in this case, the notice is of an intended effect).
- is there a way to disable the warning message via options to the GPLOT
- is there an alternate way to specify axis with irregular scaling,
without generating the warning message?
A colleague tells me of another site which was doing similar work, I'd be
interested in experiences and/or pointers to conference papers, etc.
