This function allows you to classify the values of one or several matrices and to display them as column chart. You define intervals for the classification of the matrix values. You can determine the intervals interactively or import them from a file (Using Visum: Showing matrices in a histogram).
You can also classify a matrix using a classification matrix that includes identical zones. The OD pairs are divided into defined intervals based on the classification matrix. The matrix values of the input matrix will then be summarized per interval according to this allocation.
In addition to the histogram a list is displayed showing the number and the percentage of OD pairs for both, each interval and cumulative for all intervals. If the matrix is changed, the results will be updated automatically.
This function serves for analyses of existing data for further matrix processing steps, for example aggregating data (Aggregating matrix objects). The intervals can be stored and used for other applications.
