How do I add an error bar for only one data point in a line graph

Dear people,

I've been trying to add error bars to my graph, but they really gave me a headache.

What I need to do is to add an error bar for the four categories separately. But when I add an error bar I get to choose 'Add Error Bars based on Series': DIRECT or AVERTED. But when choosing DIRECT I get the error bar for both FEAR and ANGER, but I want to set them apart from each other.

Can someone please tell me how I do this?

Kind regards,

Piet Jonker
