问题
I have a stacked bar chart that looks like this :
I would like to only show the top 3 bars in terms of value, that is to say the three first bars. I tried to use the Show/Hide feature but it doesn't work as I expected.
For example if I limit to Show top 1 value with the Show/Hide value, i get :
when I expect to also have the orange and blue bars that are stacked in the first picture.
Is there a way to do what I am looking for?
回答1:
You will have to achieve a dynamic rank and use that to filter out the top 3. Put this rank logic in the hide/show. It's not clearly given here but in ur dataset you can rank by column on x axis and say rank always less than 3.

I found a better way to do this :
Using the Show/Hide rules of the properties of the visualization, you have to add this rule
DenseRank(Sum([Value]) over (All([Axis.Color])),"desc") <= 3
Then you have to [Axis.Value] in the value input.
3 is the number of bars to have in the bar chart.
[Value] is the column of the Y Axis, in my case I used Count() because my Y axis is (Row Count).
