Ideas wanted on how to show data columns with different offset

[FlemmingA]

I have a data set with task that have bottom- and top-value, there can be several tasks on one day, but they never overlap and there can be 'space' between two task.

​​I would like to present them ala a stacked diagram, but I want to see where the various tasks lie in relation to each other. And if there is space between two tasks, it must be visible.

I have made a drawing of what I would like (or something that gives the same info), I have tried various stacked bar charts without success, I have also tried gantt without a useful result

Can anyone point me in the direction of a solution?

hello to acheive your goal 

make 3 measure

the first is sum of top 
the second is sum of bottom
the third is difference

after you do the measures

insert a stacked column chart and on x-axis put the week day and on y axis insert your 3 measure
