    Gantt chart - in/out datediff with breaks

    Piotr Adamczyk

      Hello Tableau Community!


      I would like to ask your about small help. I want to count working time and show it on the gant chart.

      How to count working hours when someone come to the work morning and made 2 brakes or more.


      I don't know who to count it without modifications in the datasource.


      I have to count all time where that worker (Card No. dimension) works and show it on gant bar.

            Hi Ashish,


            Thanks you very much for your fast feedback. I have no problem to show in/out moments on the gantt-chart. The case is to show it as a gantt-chart with something in the size like on the screenshot below:

            I have counted datediff before first "In" and last "Out" in one day. I can visualize it but I don't have any idea how to count from first "In" to the break (first "Out") and then from second "In" to second "Out" etc. and how to use it as a size to grate real gantt-bar.


            Have you got any idea without any preparation in the source file? If I prepare file like: Date | Type (in/out) | time start | time end there is no problem to count it and viz. But I can't change the input files unfortunately.


            I will be glad for any help guys!
