Is it possible to specify a different color only for the negative bar?

[Inho Lee]

Hello,

I want to change the different colors on the negative bar in my graph.

input year    month    growth_rate
2021    2    -3.463143
2021    3    -2.50773
2021    4    1.357074
2021    5    4.787192
2021    6    -2.279126
2021    7    2.595344
2021    8    2.420688
2021    9    .4742086
2021    10    5.618207
2021    11    -1.425759
2021    12    -2.704679
end

graph bar growth_rate, over(month) over(year) stack blabel(total, format(%9.1f))

I have looked up some answers, but I am having trouble applying them, so I am asking.

Thank you in advance.

Here's something applied to your data that may start you in a useful direction. I'd probably choose to suppress the legend instead of what I demonstrate.

input year    month    growth_rate
2021    2    -3.463143
2021    3    -2.50773
2021    4    1.357074
2021    5    4.787192
2021    6    -2.279126
2021    7    2.595344
2021    8    2.420688
2021    9    .4742086
2021    10    5.618207
2021    11    -1.425759
2021    12    -2.704679
end

generate gr_pos = cond(growth_rate>=0,growth_rate,.)
generate gr_neg = cond(growth_rate<0,growth_rate,.)
generate gr_null = .

graph bar gr_pos gr_neg gr_null, over(month) over(year) stack blabel(total, format(%9.1f)) ///
    bar(3, color(black)) legend(order(3 "mean of growth rate"))

It is exactly what I want. Thank you so much!
