See Values for Bullet Graph targets

[#1]

When setting targets on a bullet graph in workspace, it would be really helpful to have a callout pop up like on line graphs to show the values. Although the data is there in the tables, it can be a bit arduous to have to open up the tables to see the actuals vs the target. Since there's no way to see the target value vs the actual, we can't build a chart summary difference from them or anything.
