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 visualization).

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).

Questions:

- is there a way to disable the warning message via options to the GPLOT procedure? - 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.

Thanks.
