You can assign some numbers to those charts in layout (in show condition option), like 3 or 4.. and assign same in the button like if(vVariable=0,1,2,3,4)..assuming there are already 0,1,2
Using buttons or auto-minimizing is not limited to 3. You can use any number. However, on a practical level, if there are lots of charts you need to question the users wisdom ow wanting everything on one tab. You may be better having separate tabs to illustrate different views of data.
