Filtering matrix data

According to certain filter criteria, you can show or hide matrix data of Visum matrices.

1. Open a Matrix editor window with the matrix of your choice (Opening matrices).

Tip: You can apply pre-defined filter settings via icon Filter the matrix data view or via menu Matrix editor > Filter the matrix data view.

2. In the Matrix editor window, on the toolbar, click the button View options.

The View options of Matrix editor window opens.

Tip: Alternatively, from the Matrix editor menu, select View options.

3. In the Mode section, choose the view whose settings you want to change.

Section	Description
Matrix view	Select this option to make the settings effective in the Matrix view.
List view	Select this option to make the settings effective in the List view (Opening matrices in the List view).

4. In the Filtering section, make the desired changes.

Section	Description
Filtering by active zones	Select this option to show the matrix data of active zones only (Using filters to set network objects active or passive). Note If a main zone matrix has been opened, the labels are adjusted accordingly.
Filtering by active zone pairs	Select this option to show the matrix data of active OD pairs only (Exception: Filter for OD pairs). Note If a main zone matrix has been opened, the labels are adjusted accordingly.
Filtering by matrix values	If this option has been selected, only those matrix values are displayed which satisfy the defined filter criterion. From Smallest interval value To Greatest interval value Complement (Invert filter logic) Select this option to show all matrix intervals outside this interval. If you do not select this option, only matrix values inside the interval are displayed.

Note: You can combine these filter criteria. Use the AND operator to combine filters. Only matrix data that meets both criteria is then shown.

5. Confirm with OK.

The settings are adopted for the Matrix editor window. The icon Filter the matrix data view appears as if pressed.

Notes: Only entire rows and columns are hidden. If a matrix cell meets the filter criteria, its entire row and column are displayed. In the Matrix view, an entire row or column is only hidden if all cells of at least one matrix do not meet the filter criteria. In the List view, an OD pair (row) is only displayed if all matrix cells meet the filter criteria.

To switch off the filter, click the symbol Filter the matrix data view or call menu Matrix editor > Filter the matrix data view.

For the matrix filtered, you can save the rows currently displayed (Saving partial matrices).
