Assistance with Dynamic Button Interactions in Power BI

Hello Power BI Community,

1. Buttons:

   Primary Category Buttons:
   • "Incumbent"
   • "New Business"

• Secondary Category Buttons:
• "Direct Renewal"
• "RFP Renewal"

1. Charts:

   • Chart 1: Incumbent + Direct Renewal
   • Chart 2: Incumbent + RFP Renewal
   • Chart 3: New Business + Direct Renewal
   • Chart 4: New Business + RFP Renewal

Desired Functionality:

• Default View:
  When the dashboard loads, the Incumbent + Direct Renewal chart should display by default.

• Button Toggles:

  • At any point, one button from the Primary Category (Incumbent/New Business) and one button from the Secondary Category (Direct/RFP Renewal) should always be active.
  • For example, if "Incumbent" and "Direct Renewal" are selected, I can click "RFP Renewal" to switch to the Incumbent + RFP Renewal chart.
  • Similarly, selecting "New Business" would switch the view to charts involving "New Business" (e.g., New Business + Direct Renewal or New Business + RFP Renewal) while maintaining the toggle functionality between "Direct Renewal" and "RFP Renewal."

Challenge:

I’m looking for guidance on how to:

1. Configure the buttons to ensure one button from each category is always active.
2. Dynamically update the displayed chart based on the button selections.
3. Maintain a seamless user experience while toggling between categories and charts.

I’ve created a sample dataset and Power BI file for reference

Any advice, examples, or best practices to achieve this functionality would be greatly appreciated!
