line in ggplot connects all dots and not only those in group

I have molten dataframe and wants to plot all the different variables with a line. However when i do that GGplot connects all lines and the plot is meaningless.

df <-data.frame (names =c("a","b","c","a","b","c"),
   time = c(1,1,1,2,2,2),
   xvar = c(150,37,38,150,50,50))

ggplot(df,aes(x=time, y=xvar), group = names)+
  geom_line()

Can this be fixed, so the plot shows three lines connecting the dots in each variable

You put the group outside of the aes(). It needs to be inside the aes():

ggplot(df,aes(x=time, y=xvar, group = names)) +
  geom_line()
