Estimating Weight and CoG
3.4 Graph options
Under the Graph menu in the estimation dialog, many options are available for
displaying different information in the graph.
Most important are the regression line and the choices regarding the
regression type. If Auto is checked in the menu, the system chooses the
regression line that gives the lowest standard deviation coefficient. However, it
is important to remember that if the number of coefficients is low, it might be
wise to judge yourself if other types of regression line are more appropriate.
By ticking off the Auto option, the user is free to decide whether linear,
logarithmic, exponential or power regression should be used.
Other useful options in the Graph menu are options to view default coefficient,
labels, standard deviation and average coefficient. A blue- and a green dotted
line in the graph display the default and average coefficient. The label option
will label the coefficients plotted in the graph with the ID (filename) of the
project. The two gray lines display the standard deviation.
