- Put your continuous measure onto Columns and discrete Month into Rows. In my case, I used the Median of Profit (from the Superstore dataset)
- Drag the dimension that you want to split the view up by into Detail. In my case, I used Postal Code
- Change the mark type from automatic to Gantt Bar
- Reduce the opacity of the Colour. This is so you are able to better distinguish between each line
- Colour the view as you please. I decided to colour the lines based on whether they were above or below the median for each month. This was achieved via a calculated field:
MEDIAN([Profit]) > WINDOW_MEDIAN(MEDIAN([Profit]))
