Sorting the Data
DataLab provides a simple means for sorting the data of the data matrix. The sorting process is controlled by several parameters and can be applied to the whole data matrix or to only parts of it. After clicking the command Tools/Sort..., a window is displayed which allows the user to select the parameters of the sorting process:
The user may select the sort range, the sort criterion, and the sort order. The sort range is indicated by the yellow area in the right part of the window. The sort range is also displayed numerically above the graphical display. It may be adjusted by changing the slider positions besides the graphical representation.
The sorting process may be controlled by one of the following sort criteria. If either sorting by row or by column is selected, the sort criterion is indicated by a red line in the graphical display. The sort criterion may be adjusted either by clicking into the matrix image, or by using the spin edit boxes, or the ellipses button in the left half of the form:
The sort order can be adjusted to be either ascending or descending. The user should note, that the object and class identifiers (or the variable identifiers) are always sorted along with the data - even if only a limited part of the data has been selected for sorting.
