Diagram date axis without grouping

Hello,
I have values from a performance measurement - timestamp and value.
I would like to display them as a bar chart.
But it seems that I only have the choice to display all performance values as columns with equal spacing - because if I switch the axis to date axis, so that the columns are displayed according to their time distribution, all values of a day are grouped together - which I do not want under any circumstances.

Is there another option where the columns are displayed unevenly according to their timestamp?

Thanks
