We will need some more information in order to help you. What does not work, the data importation or making the chart? Please show the code you run and any errors you get. If you are successfully importing the data, include all or a subset of your data in your reply. If the data are stored in a data frame named DF, you can post the output of
dput(DF)
If the data set is large you can select the first 20 rows with
dput(head(DF, 20))
