| clhisto | Computing histograms for classes |
| -c <cldata> | classified data for defining classes |
| -f <field> | source field |
| -dout <trgdata> | target data for statistics in classes |
| [-max <num-categ>] | the number of the categories (default 2) |
This operation computes histograms for a given field in the classes defined by <cldata>. The result will be a frame presented in the figure below. The frame hst has the field hst.x containing places for pins in the x-axis and data frame hst.data to store actual fields for pins. One class is represented as one data record.
