| 43 **Syntax** | |
| 44 | |
| 45 This tool computes a histogram of the numerical values in a column of a dataset. | |
| 46 | |
| 47 - All invalid, blank and comment lines in the dataset are skipped. The number of skipped lines is displayed in the resulting history item. | |
| 48 - **Column for x axis** - only numerical columns are possible. | |
| 49 - **Number of breaks(bars)** - breakpoints between histogram cells. Value of '0' will determine breaks automatically. | |
| 50 - **Plot title** - the histogram title. | |
| 51 - **Label for x axis** - the label of the x axis for the histogram. | |
| 52 - **Include smoothed density** - if checked, the resulting graph will join the given corresponding points with line segments. | |
| 53 | |
