after having checked various visual to create a gantt chart I decide to create my own, as per the format I used to do in MsExcel, below screenshoot (a stacked histogram with blank filling and border for the first data set for the start date)
the source data is the following table
I here attached the MsExcel file with the raw data and the PBIX with my attempt
When in power BI i choose the stacked histrogram, laid horizontal i I got as per follow screenshoot
In the values field does not let me drag in the Measure, while if I drag the start date it does automatically do count and can not change the aggregation
The measure for the start date is
Start Date = FORMAT ( MIN ( Dates[START]) , “#,##0” )
Looking forward for your support.
