使用 ggplot 在 R 中创建分组条形图

Question

I'm trying to create a grouped barplot using ggplot due to the more aesthetically pleasing quality it produces. I have a dataframe, together, containing the values and the name of each value but I can't manage to create the plot it? the dataframe is as follows

          USperReasons      USperReasonsNY                 USuniquNegR
1    0.198343304187759   0.191304347826087                 Late Flight
2     0.35987114588127   0.321739130434783      Customer Service Issue

I tried different methods with errors in all, one such example is below

ggplot(together,aes(USuniquNegR, USperReasons,USperReasonsNY))+ geom_bar(position = "dodge") 

Thanks, Alan.

Answer 1

df <- reshape2::melt(together, 3)

ggplot(reshape2::melt(df, 3), 
    aes(USuniquNegR, value, fill = variable)) + 
        geom_bar(stat = 'identity', position = 'dodge') + 
        coord_flip() + 
        theme(legend.position = 'top')
