How to make a chart appear based from 2 buttons

[shnqqs]

Hi,

I would like to make a chart appear based from 2 buttons.

Here is the scenario that:

I need to come out with number of headcount based on staff category(top management/Executive/Non-Executive) and across time dimension(monthly/quarterly/yearly).

Hence, I want to create 2 buttons which is:

1. Staff category (Top management/Executive/Non-Executive)

2. Time dimension(monthly/quarterly/yearly)

So, the problem I am facing now is to combine these 2 buttons in the conditional expression for to make the chart appear for a different combination of these 2 buttons.

Thanks in advance for any helps!
