求创建类似指定页面的Tableau Dashboard Filter（点击左侧联动地图）

Hey there! Let's walk through how to build that interactive filter-to-map dashboard in Tableau, just like the 3W-style view you're aiming for. This relies on Tableau's built-in Action Filters to link your left-side selection panel with the right-side map. Here's a detailed, actionable example:

We'll create two linked views: a clickable selection panel on the left, and a geographic map on the right. When a user clicks an option in the left panel, Tableau will automatically filter the map to show only the corresponding data.

1. Prep Your Dataset #

First, make sure your data includes these key fields (adjust based on your use case):

• Geographic data: Region names, latitude/longitude coordinates (Tableau can auto-generate coordinates for known regions, but explicit lat/lon is more reliable)
• Filter dimension: The category users will click on (e.g., Cluster Type, Organization, Activity Sector)
• Metric: The value you want to visualize on the map (e.g., Number of Projects, Beneficiary Count)

Sample data structure:

2. Build the Left-Side Selection Panel #

• Drag your filter dimension (e.g., Cluster Type) to the Rows shelf
• Change the view type to a Text Table (or Tree Map if you need hierarchical categories)
• Customize the formatting: Remove grid lines, adjust font size, and set a clean background to make options easy to click
• Rename this worksheet something clear, like Cluster Selection Panel

3. Build the Right-Side Map View #

• Drag your geographic field (e.g., Region Name) to the Marks > Geographic shelf — Tableau will auto-generate a base map
• Drag your metric (e.g., Project Count) to Marks > Size (to make larger values bigger) and/or Marks > Color (to add a color gradient)
• Rename this worksheet Regional Project Map

4. Set Up the Interactive Action (Critical Step!) #

This is what makes the click-to-filter magic happen:

1. Go to the top menu: Worksheet > Actions
2. Click Add Action > Filter
3. In the action configuration window:
   • Source Sheets: Select your left-side panel (Cluster Selection Panel)
   • Target Sheets: Select your right-side map (Regional Project Map)
   • Trigger: Choose Select (so the filter activates when a user clicks an option)
   • Filter Action: Select Keep Only Selected Values
   • Optional: Check Show Selected Marks in View to highlight the clicked option in the panel
4. Click OK to save the action

5. Assemble the Dashboard #

• Create a new dashboard by clicking Dashboard > New Dashboard
• Drag your Cluster Selection Panel to the left side of the dashboard, and Regional Project Map to the right
• Adjust the layout sizes to fit your design (e.g., make the panel narrow and the map wide)
• Test it out: Click any cluster in the left panel, and the map will instantly update to show only that cluster's projects!

• Enable multi-select: Hold Ctrl (Windows) or Cmd (Mac) to click multiple options, or adjust the action settings to allow multi-select by default
• Add highlighting: Create a Highlight Action to make the clicked option stand out in the panel
• Add tooltips: Customize map tooltips to show extra details (e.g., region name, project count, partner organizations)
• Use hierarchies: If your data has nested categories (e.g., Country > Province > District), build a hierarchy to let users drill down further
