Hi.
I want to give both the Yes bars a different color from the two No bars. How can this be done.

Here's the code that I used for the graph at the end. Thanks

histogram Difficult_Readings_edit, discrete percent by(Outstation, title("Difficulty in Accessing Readings" ) noixtick ///
legend(off)) graphregion(fcolor(white)) lcolor(white) gap(8) ///
addlabel addlabopts(mlabsize(small) mlabposition(6) mlabgap(2)) xtitle("") by(, note("")) xla(0 1, valuelabel ) xscale(noline)
Array
