p2 <- ggplot(data=dataz, aes(x=dataz$Age.Group, y=dataz$Bad.Loans)) + geom_bar(stat="identity", width=0.4, color="white", fill="steelblue")
p3 <- ggplot(data=dataz, aes(x=dataz$Age.Group, y=dataz$Good.Loans)) + geom_bar(stat="identity", width=0.4, color="white", fill="red")
p4 <- ggplot(data=dataz, aes(x=dataz$Age.Group, y=dataz$Bad.Rate)) + geom_bar(stat="identity", width=0.4, color="white", fill="gold")
