Why does the graph label only appear sometimes?

[mariko5797]

I want the counts of each bar to show, but it only shows sometimes. Is there something wrong with the program or is this a SAS issue? Thank you in advance.

proc sgpanel data = work_comp;
 panelby BMIGRP ABRV_SPECTYPE / layout = lattice onepanel novarname;
 histogram PCOMP / scale = count datalabel = count;
run;

Notice that only the bars with a single-digit value are being labeled. The other labels are dropped because the bars are too narrow and would cause a collision. If you make the graph a little wider, the values should appear.
