Additional Bar graph when selected

Hi,

you can try to use a stacked column visual and customize the data colors for each category.

If you create a stacked column with categories in the legend and a Filter by Category you will hace something similar to:

Then you can customize Data Colors in the Format Menu (first categories in green and categories 7 & 8 in red):

Finally you will have this visual:

If you filter first categories, the columns appear in green color, but if you include 7 & 8 they will appear in red.

Other way is to create value groups in the Category field in order to assign each group a color:

You can create a group for categories 7 & 8 and it works like a grouped value. Let's say you create a group for categories from 1 to 6 and call it "Green Categories" and another group for categories 7&8 called "Red Categories". Then you can add a slicer by Category Groups.

Perfect! Thank you so much for your advice.
