you have a ton of Show Values there. every show value is going to create one series of bars in the chart.
if you are trying to show bars which add up all of the fields, one bar for each year, then you need to create a formula that adds up all of the fields. i.e. you should only have one Show Value.
1) create a new formula and then add up all of the fields that you currently have in the Show Value dialogue.
2) remove all of the current fields from the Show Value dialogue
3) add in the new formula to the Show Value dialogue
