This article mainly introduces the ggplot2 Cartesian coordinate system x, y axis how to exchange the relevant knowledge, the content is detailed and easy to understand, the operation is simple and fast, has a certain reference value, I believe that after reading this ggplot2 Cartesian coordinate system x, y axis exchange article will have something to gain, let's take a look.

Library ('ggplot2') library (' reshape2') A = c ("A", "B", "C", "D", "E") B = c (9014) dat = data.frame (A type, "sample1", "sample2") dat = melt (dat,variable.name= "Sample", value.name = "Num") head (dat) p = ggplot (dat, aes (x = type,y = Num) Fill = Sample) + geom_bar (stat = "identity", width= 0.6 position = position_dodge (width=0.8)) + scale_fill_manual (values = c ("red", "blue")) + labs (x = "", y = ", title =" test ") + geom_text (aes (label = dat$Num), position=position_dodge (width= 0.9), size = 5 Vjust =-0.25) + guides (fill = guide_legend (reverse = F)) + theme (plot.title = element_text (size= 25pint face = "bold", vjust = 0.5, hjust = 0.5), legend.title = element_blank (), legend.text = element_text (size= 18, face = "bold"), legend.position = 'right', legend.key.size=unit (0.8 camera cm') p=p+coord_flip () p

However, it can be seen that after the coordinate exchange, the original settings need to adjust the position of the text in the text layer, specifically adjust vjust and hjust. For example:

Library ('ggplot2') library (' reshape2') A = c ("A", "B", "C", "D", "E") B = c (9014) dat = data.frame (A type, "sample1", "sample2") dat = melt (dat,variable.name= "Sample", value.name = "Num") head (dat) p = ggplot (dat, aes (x = type,y = Num) Fill = Sample) + geom_bar (stat = "identity", width= 0.6 position = position_dodge (width=0.8)) + scale_fill_manual (values = c ("red", "blue")) + labs (x = "", y = ", title =" test ") + geom_text (aes (label = dat$Num), position=position_dodge (width= 0.9), size = 5Covjust = 0.5 Hjust=-0.25) + guides (fill = guide_legend (reverse = F)) + theme (plot.title = element_text (size= 25 bold = "bold", vjust = 0.5, hjust= 0.5), legend.title = element_blank (), legend.text = element_text (size= 18, face = "bold"), legend.position = 'right', legend.key.size=unit (0.8) 'cm')) p=p+coord_flip () p on "how the x and y axes of the ggplot2 Cartesian coordinate system are interchanged" ends here. Thank you for reading! I believe that everyone has a certain understanding of the knowledge of "how to exchange the x and y axes of ggplot2 Cartesian coordinate system".
