The grouping variable is displayed at the top of the graph where the fill in odd years in blue and no fill in the even years. How do I change the code so that a grey fill color is used in odd years and keep the no fill (or white) in even years? I tried the cblockvar= option for the block variable legend, but have not been able to change the color.<BR /> Thanks<BR /> <BR /> proc boxplot data=precip_boxplot1;<BR /> plot precip*Watershed(year)/blockpos=1 blocklabelpos=above cblockvar= vminor=4 boxstyle=skeletal<BR /> nohlabel cboxfill=GRAYFF;<BR /> label year='Year'<BR /> precip='Precipitation (mm/yr)';<BR /> run; Wed, 03 Feb 2010 15:10:34 GMT https://communities.sas.com/t5/SAS-Procedures/boxplot-fill-color-for-blocking-variable/m-p/51459#M14119 deleted_user 2010-02-03T15:10:34Z https://communities.sas.com/t5/SAS-Procedures/boxplot-fill-color-for-blocking-variable/m-p/51460#M14120 check the options of cbox=(variable) and cboxfill=(variable) from the tech documentations. these will allow you to assign desired color and fill to a variable (years in your situation). you will need to create this color variable in your dataset precip_boxplot1.
