Issue with barplot ggplot2

Question

[Nitin]

I have following data

d1 d2

a -9.278

b -5.582

c -5.266

d -5.01

e -3.833

I wrote R code to plot barplot as follows

library(ggplot2)

dat<-read.csv("input.csv",sep=",")

dat1<-dat[,-3]

ggplot(dat11,aes(x = d1, y = d2)) +

geom_bar(fill="#e34a33",width=0.34,stat="identity") +

scale_x_discrete(limits=dat1$d1) +

coord_flip() +

theme_bw() + theme(legend.position = "none", panel.grid.major=element_blank(),

                 panel.grid.minor=element_blank(),legend.key = 

element_blank(),axis.title.x = element_text(size=15),axis.text.x =

element_text(size=16), axis.title.y =

element_text(size=15),axis.text.y=element_text(size=17),

panel.border = element_rect(colour = "black",size=0.7))

This code gave the plot as follows

But this plot has problem bars are on right side but it should be towards left and x axis should start 0 to -10. Can any body to suggest soultions for this problem

Thanks, Sa

What about this? (NB: Usually these questions are better suited to StackOverflow or R mailing list)

library(ggplot2)

dat1<- data.frame(d1= c(-9, -5, -4, -3), d2= c('a', 'b', 'c', 'd'))

ggplot(data= dat1, aes(x = d2, y = -d1)) +
    geom_bar(fill="#e34a33", width=0.34,stat="identity") +
    coord_flip() +
    scale_y_discrete(breaks= seq(0, 10), labels= seq(0, -10)) +
    theme_bw() + theme(legend.position = "none",
        panel.grid.major=element_blank(),
        panel.grid.minor= element_blank(),legend.key = element_blank(),
        axis.title.x = element_text(size=15),
        axis.text.x = element_text(size=16),
        axis.title.y = element_text(size=15),
        axis.text.y=element_text(size=17),
        panel.border = element_rect(colour = "black",size=0.7))

Hi

Plot absolute values to change plot orientation.. : aes(x = d1, y = abs(d2))

use scale_y_continuous(limits=c(-10,0)) to get the scale up to 10.
