Create a bar chart with 2 dimension and one measure. After that, color the bar chart using the third dimension(use 'Color by dimension' in Color and legend tab) or use color by expression(using the third dimension for custom coloring).
I just had this issue and found a solution that worked for me:
1 - Create your bar chart with the 3 dimensions and 1 measure
2 - Make sure your most outward dimension (if you are doing year/month/week, it would be year) is listed first.
3 - On the 'Dimensions' page, click the 'Trellis' button.
4 - If you have a fixed number of years (or first dimensions) this will work best, but now check 'Enable Trellis Chart', then for number of columns, select your fixed number, and number of rows, select 1.
