Graphical presentation of the results of the automated analysis of the SCCN strings of the karyotypes of 94 Ph positive ALL cases with respect to qualitative chromosome changes. The number of events recorded at a chromosome (sub)band is indicated by a bar projecting onto the respective chromosome ideogram. The lengths of the bars are relative to the maximum number of events at the respective chromosome. The minimum and maximum values are given.
