df <- data.frame(season=c("2000","2000","2001","2001"), game=c(1,2,1,2),value=c(1:4))

#Initial scatter plot
p <- plot_ly(df, x = game, y = value, mode = "markers", color = season)

#subset of data
df1 <- subset(df,season=="2001")

#add line
p %>% add_trace(x = df1$game, y = df1$value, mode = "line")
