Security & Support
DendroMap Explorer processes all dashboard data locally within your Tableau environment. The extension collects pseudonymous usage data (organization hash, user hash, session UUID, feature events) for product analytics. We do not collect dashboard content, credentials, or personal information. Processing is based on Legitimate Interests (GDPR Art. 6(1)(f)). See our Privacy Policy and EULA.
Installation Guide
Important: DendroMap Explorer is currently a dashboard extension (not a worksheet extension), which means it requires a manifest file for installation and works at the dashboard level.
Configure Tableau Server/Online
Before installing the extension, your Tableau Server administrator needs to allow it:
- Navigate to Settings → Extensions in your Tableau Server/Online
- Click "Add URL" and enter:
https://dendromap-explorer.netlify.app/ - Configure security settings:
- Full data access: Deny
- User prompts: Hide
This configuration ensures the extension can only access data you explicitly provide through worksheets, maintaining your data security. Learn more about Tableau Extensions security.
Get the Manifest File
Contact me to receive the DendroMap Explorer manifest file (.trex) - this is a secure connector that enables Tableau to verify and communicate with the extension web application.
Prepare Your Worksheet
- In your Tableau workbook, create a new worksheet
- Add your dimension fields in the desired order to Rows or Columns (e.g., Region → Country → City)
- Add at least one measure field to the view or use Measure Values
- The extension will automatically detect and configure your data structure
Note: You don't need to create a formal hierarchy in Tableau - simply arrange your dimension fields in the order you want to drill down. The extension works with any combination of dimensions and measures.
Add to Dashboard
- Create a new dashboard or open an existing one
- Drag your prepared worksheet onto the dashboard
- You can hide the worksheet by:
- Making it 1 pixel in size
- Using either tiled or floating layout
Install DendroMap Explorer
- From the dashboard's Objects panel (bottom left), drag an Extension object onto your dashboard
- In the dialog that appears, click "Access Local Extensions" at the bottom
- Browse and select the DendroMap Explorer manifest file (.trex)
- The configuration window will open automatically
- In the "Select Worksheet" dropdown, choose the worksheet you prepared
- Click Save
Once configured, DendroMap Explorer will appear on your dashboard, ready to visualize your hierarchical data. The original worksheet remains hidden, serving only as the data source.
