You can use two hidden combo boxes to get filtered data from a block.
1. First create a column for Local/Foreign flag with formula as shown below:
2. Allocate two blocks in excel for filtered data insertion for Local and Foreign respectively as shown below:
3. Then add a combo box to canvas and select Local/Foreign flag column(here Sheet1!$B$3:$B$8) as label.
4. Select Filtered Rows as insertion type.
5. Insertion source: your data grid coming from connection(Here Sheet1!$D$3:$F$8).
6. Destination: The block allocated for data filtered for local(here Sheet1!$H$3:$J$8).
7. Have two cells with hard coded value as 1 and 0.
7. In behavior tab of combo box, bind the default selected item to 1(here Sheet1!$B$10). Keep type as Label.
8. Similarly create another combo box having filtered row insertion type and with same labels and source but destination with the block allocated for foreign. Bind the default selected item label to 0.
9. Now hide the two combo boxes behind some visual component. On opening the dashboard, you will get two filtered blocks of data as required. Now, you can create different charts based on the filtered blocks.
