Hello
is there a way to replace blank cells with -1 in my graph code below (Product_rating field has blank cells so need to replace that with -1):
axis1 label=None;
axis2 label=('Product_rating') order=(-1 to 20 by 2);
title 'Product rating';
proc gchart data=Prod_list;
vbar3D product_rating/ discrete noframe
subgroup=product_class
raxis=axis1 maxis=axis2
autoref clipref cref=graybb
coutline=black woutline=1;
run;
quit;
