You can use the "change" and "condition" on your checkbox XML code to choose with panels to show, but this have a problem for checkbox and multiselect, that is the order the user select the options will change the value of your token.
Using a Radio button is easier, but you will have to write all the options, that in your case are 7 options ( panel1, panel2, panel3, panel 1 and 2, panel1 and 3, panel2 and 3, all panels)
Considering 3 panels with depends on tokens $p1$, $p2$, $p3$, you can create the radio button and for each one use the code to set\unset the token or create the checkbox\multiselect and map all the possible combinations of values.
For 3 panels is easy, but if the number os panels increase, this can be problematic.
Code for the Radio buttons :
<input type="radio" token="radio">
<label>Radio</label>
<choice value="p1">p1</choice>
<choice value="p2">p2</choice>
<choice value="p3">p3</choice>
<choice value="p1 p2">p1 and p2</choice>
<choice value="p1 p3">p1 and p3</choice>
<choice value="p2 p3">p2 and p3</choice>
<choice value="p1 p2 p3">All</choice>
Code for the Checkbox :
<input type="checkbox" token="checkbox">
<label>Painel:</label>
<choice value="p1">Panel1</choice>
<choice value="p2">Panel2</choice>
<choice value="p3">Panel3</choice>
<prefix/>
<suffix/>
<valueSuffix></valueSuffix>
Code for the change and set\unset :
<change>
<condition match="$checkbox$==""">
<unset token="p1"></unset>
<unset token="p2"></unset>
<unset token="p3"></unset>
</condition>
<condition match="$checkbox$=="p1"">
<set token="p1">1</set>
<unset token="p2"></unset>
<unset token="p3"></unset>
</condition>
<condition match="$checkbox$=="p2"">
<set token="p2">1</set>
<unset token="p1"></unset>
<unset token="p3"></unset>
</condition>
<condition match="$checkbox$=="p3"">
<set token="p3">1</set>
<unset token="p1"></unset>
<unset token="p2"></unset>
</condition>
<condition match="$checkbox$=="p1 p2" OR $checkbox$=="p2 p1"">
<set token="p1">1</set>
<set token="p2">1</set>
<unset token="p3"></unset>
</condition>
<condition match="$checkbox$=="p1 p3" OR $checkbox$=="p3 p1"">
<set token="p1">1</set>
<set token="p3">1</set>
<unset token="p2"></unset>
</condition>
<condition match="$checkbox$=="p2 p3" OR $checkbox$=="p3 p2"">
<set token="p2">1</set>
<set token="p3">1</set>
<unset token="p1"></unset>
</condition>
<condition match="$checkbox$=="p1 p2 p3" OR $checkbox$=="p1 p3 p2" OR $checkbox$=="p2 p1 p3" OR $checkbox$=="p2 p3 p1" OR $checkbox$=="p3 p1 p2" OR $checkbox$=="p3 p2 p1"">
<set token="p1">1</set>
<set token="p2">1</set>
<set token="p3">1</set>
</condition>
