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).

2.  Click the black triangle next to the symbol on the Matrix Editor window toolbar.

3.  Select Set filter.

The Set filter window opens.

4.  Make the desired changes:

Section

Description

Filter 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.

Filter by active OD 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.

Filter by matrix values

If this option has been selected, only the matrix values within the set range are displayed.

From

The lowest value of the range

To

The highest value of the range

Invert (use values outside the range)

Select this option to show all matrix intervals outside this range.

If you do not select this option, only matrix values inside the range 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.

You can switch filters on and off using the filter symbol .

Notes: You can also apply the matrix filter in histograms and matrix comparisons. The matrix comparison then shows only pairs of values that satisfy the filter conditions. When filtering by matrix values, both values must satisfy the condition for the pair to be included in the comparison.

Only the matrix entries that meet the conditions are displayed in the histogram. If a classification matrix is combined with a condition on the matrix values, the value of the matrix itself must satisfy the condition, not the value of the classification matrix. So, if there are several matrices, then for the same OD relation the value of one matrix may enter and that of another may not.
