How can I change the Y-axis figures into percentages in a barplot

Question

How can we change y axis to percent like the figure  I can change y axis range but I can t make it to percent

User · Answer

Use     scale y continuous labels   scales  percent    Or  to specify formatting parameters for the percent     scale y continuous labels   scales  percent format accuracy   1      the command labels   percent is obsolete since version 2 2 1 of ggplot2

In principle  you can pass any reformatting function to the labels parameter     scale y continuous labels   function x  paste0 x 100          Multiply by 100  amp  add       Or       scale y continuous labels   function x  paste0 x          Add percent sign      Reproducible example    library ggplot2  df   data frame x seq 0 1 0 1   y seq 0 1 0 1    ggplot df  aes x y        geom point       scale y continuous labels   function x  paste0 x 100

Borrowed from  Deena above  that function modification for labels is more versatile than you might have thought   For example  I had a ggplot where the denominator of counted variables was 140   I used her example thus   scale y continuous labels   function x  paste0 round x 140 100 1         breaks   seq 0  140  35     This allowed me to get my percentages on the 140 denominator  and then break the scale at 25  increments rather than the weird numbers it defaulted to   The key here is that the scale breaks are still set by the original count  not by your percentages   Therefore the breaks must be from zero to the denominator value  with the third argument in  breaks  being the denominator divided by however many label breaks you want  e g  140   0 25   35

ggplot2 and scales packages can do that   y  lt - c 12  20  100 x  lt - c 1  2   library ggplot2  library scales  myplot  lt - qplot as factor x   y  geom  bar   myplot   scale y continuous labels percent      It seems like the stat   option has been taken off  causing the error message  Try this   library scales   myplot  lt - ggplot mtcars  aes factor cyl                 geom bar aes y      count    sum   count                   scale y continuous labels percent   myplot
