Typically when you want to display values for specific Dimensions and you have a good number of them, the best graph is a scatter plot but then you have dates in the mix and with dates, line charts/graphs are the norm. I'd go back and better undestand what the audience of the chart needs and try to build based on information being desired. For instance, if this is for selecting data related toa specifiic user, then a top page listing all the users that then shows a detailed graph when the user is selected would work. I did something like this recently for our teammembers working at Tableau Conference. A user could select their own name and then they would see a view that included just their shifts by date.
I hope that helps.
