Sure there's a way to do that.
You can use buttons to display your reports instead of containers.
You'll also need 1 variable that you'll use in the conditional show property of the charts, let's say vShow.
Triggering any of the buttons will set the related variable value and thus displaying only the related charts.
For example in your case, create 3 buttons: Truant, Chronic and EEA.
In their properties, go to Actions > Add > External > Set Variable.
Type in the variable field vShow and in the Value field type Truant (then Chronic for the 2nd button and EEA for the 3rd).
Now in each of the charts, go to their properties > Layout > Show > Conditional.
Type: Match(vShow, 'Truant'), etc...
That's it !
This solution is now working for me, but I thought I'd leave this comment here for any other newbies who stumble onto this page.
There was one step missing from jp's instructions, probably because it seemed like a given.
However, being so new to QV dev (and not having adequate training), I was unable to get this solution to work until I did one more step:
Settings > Document Properties > Variables > New...
I needed to create the variable 'vShow' before I could use it. Obvious in hindsight, but I hadn't been introduced to variables yet.
