Bug in SGPLOT when using max= in yaxis statement

BruceBrad — Fri, 22 Aug 2025 12:16:17 GMT

The attached image shows the output from two sgplot statements. The syntax for the bottom (incorrect) image is below. The syntax for the (correct) top image is identical, except that the "max=18" text is omitted. (See, for example the point for 2010, it should be 13.1). Using the max statement seems to shift the axis down.

%let cl = curvelabel CURVELABELLOC=OUTSIDE CURVELABELPOS=max curvelabelattrs=(size=12);
proc sgplot data=medians_rates_comb;
  label date="Year (Jan)";
  series y=ABS_P50_AHY_C8_RcZS x=date  
           /lineattrs=(thickness=4 pattern=solid)
           markers markerattrs=(size=8 symbol=circlefilled) &cl;
  yaxis label="%" labelpos=center minor grid minorgrid 
        labelattrs=(size=14) valueattrs=(size=12) valuesformat=f3.1 min=5 max=18;
  xaxis  grid minor minorgrid labelattrs=(size=12) valueattrs=(size=12) ;
  run;

I thought it had uploaded. Anyway here it is again. Actually, on a bit more reflection, it might be the min= statement that triggers the problem. I get the same problem recurring when extra data points push the axis higher. Now I'm using a values statement, which seems to work. But it seems to me that this is a bug.

Hello @BruceBrad,

I have measured the y-coordinates of the tick marks and the point in question (in the bottom image) and obtained 13.14 for the value -- so no indication of a bug. Note that the y-axis tick mark label "13" may be a bit misleading because it is rounded up from 12.5 due to the insufficient width of the format specification

valuesformat=f3.1

"Note that the y-axis tick mark label "13" may be a bit misleading because it is rounded up from 12.5 due to the insufficient width of the format specification"

Well spotted! I didn't expect that would happen (and yes, the format should be wider).
