I am trying to create a graph in R that looks similar to a Gantt chart (see the attached image for reference) but with a variable Y-axis for the amount of minutes a player has played.
I've tried the standard plot but it only allows for one X-axis value for each player.
The the dataset is below.

CodePudding user response：
If you supply your code, then it'll be easier to coach into what else to try. Though, from your question, I assume you're using geom_point(), while what will work is geom_segment(), when you can specify start and finish.
As a start, try (where df is the data):
df %>%
ggplot()
geom_segment(aes(x = age_start, xend = age_end, y = player, yend = player), lwd = 2, colour = "magenta")
I didn't see how the percentages were derived, but these would be the y and yend.

You can do this in ggplot using geom_segment. A simplified version of your data and plot (without color, because I don't know what is used as gradient color variables):
set.seed(9)
n<-10 #number of player
player<-letters[1:n] #player names
age_start<-rnorm(n,20,3)
age_end<-age_start runif(n,1,10)
minutes<-runif(n,10,3000)
df<-data.frame(player,age_start,age_end,minutes)
library(ggplot2)
ggplot(data=df,aes(x=age_end,y=minutes))
geom_segment(aes(x=age_start,xend=age_end,y=minutes,yend=minutes))
geom_text(aes(label = player, x = age_end, y = minutes, hjust = -.5))
xlab("age")
See, plot.
