Syntax

This tool computes a histogram of the numerical values in a column of a query.

• All invalid, blank and comment lines in the query are skipped. The number of skipped lines is displayed in the resulting history item.
• Column for x axis - only numerical columns are possible.
• Number of breaks(bars) - breakpoints between histogram cells. Value of '0' will determine breaks automatically.
• Plot title - the histogram title.
• Label for x axis - the label of the x axis for the histogram.
• Include smoothed density - if checked, the resulting graph will join the given corresponding points with line segments.
