How to stop summarizing values with different other values

Hi all,

I'm trying to make a bar chart, based on an excel-file (whihc I can not share here unfortunately).

On X-axis, the in-clinc period (each one is unique, even though they moght occur more than once). On Y-axis, the value per in-clinic period.

As you see, if the in-clinic period is 6 days, it shows multiple studies with that amount of in-clinc period, and it adds the values. I want those next to eachother.

I can do that If I change the Y and X axes, but then it shows all very thin bars and it looks crap. Could please somebody help me? Am I missing something here?

Rgds,

Felix
