This graph is basically all right, but I don't think it is necessary to have that starting point zero in it. In this graph, for example, it is only the hours from 10 to 13 that I want to visualize. So, should I fix the x-axis so that the limits would be 10 and 13, or is there another approach that I should use?
The code
df %>%
filter(Time !="-") %>%
separate(Time, c("hour", "minutes"), sep = ":", convert = TRUE) %>%
filter(between(hour, 10, 13)) %>%
ggplot() +
aes(hour) +
geom_freqpoly(binwidth = 1)
