    3434== Histograms ==
    35 The global histograms of the vector components  are available in the lower left windows. Histograms limited to a sub-region can be extracted by the menu bar tool '''[Projection object]''', selecting either ['''rectangle]''', '''[ellipse]''' or '''[polygon]''' to define the sub-region (see [wiki:Tutorial/ProjectionObjects: projection objects])

    3737== Profiles ==
    38 The velocity profile along a line can be obtained by creating a line with the upper menu bar '''[Projection object/line]''', like for image luminosity (see [wiki:"Tutorial: projection objects" Tutorial: projection objects]). Press (and release) the left hand side mouse button, draw the line, and pres it again for the end of the line. The transverse and longitudinal velocity components along this line are then plotted in a new  figure '''view_field'''.
