Selecting the points in the high end of the weight scale shows which country makes the heaviest cars. Selecting the US bar in the bar chart shows how the cars built in the US compare to those built in other countries. Just do the analysis once to show Data Desk what you want. Data Desk's visual Action Control Language lets you add loops, conditional decisions, and other basic controls with no need ever to write a program or macro. The example show a template to compute an F test for the ratio of two variances.
Many exciting templates are available, and more are being contributed by users all the time.
So, if you want to reposition the points in a plot, don't tell Data Desk where to plot them verbally, pick them up with the hand tool and move them. If you want to identify a point, click on it. If you want to change the color or symbol of a point select it and click on the desired color or symbol in the palettes. If you want to rotate points in a rotating plot, push them. If you want a new variable on the x-axis of a plot, pick up its icon and place it on the axis.
