Enlarging or reducing the stick figure

The method for scaling the stick figure varies depending on whether you wish to enlarge a

real-time or data file view.

To scale a data file view:

Choose Zoom stick figure view from the Views menu, or select the magnifying glass

toolbar button.

Click the mouse button over the point of most interest in the stick figure view.

Drag the mouse up to make the view bigger, and down to make it smaller.

To scale a real-time stick figure:

The scaling of a real-time view is a much more complex operation, and you may be best

advised to leave this at its default scaling. The size of the view depends upon the viewing

limits specified in the stick figure viewing Options dialogue box. These specify the section

of the field of view which should be scaled to fit in the window. All values should be in

millimetres, and all values are relative to the current marker origin (see Preparing for

data acquisition for more information).

First, you must find the section of the field of view which you wish to view. One way to

do this is to use the marker positions view to find the positions of the markers you are

interested in, in the field of view. This assumes that you have already defined the

marker origin.

Select Display Marker Positions from the CODA menu.

Look at the positions of the markers which you are interested in. Find separate

maximum and minimum X, Y, and Z co-ordinates.

Select the stick figure view you wish to enlarge.

Select stick figure viewing Options from the Views menu.

In the dialogue box, type in the maximum and minimum viewing limits which you have

found. It is usually sensible to decrement the minima by a few centimetres, and

increment the maxima by a few centimetres. A bigger range between the maximum

and minimum viewing limits will result in a smaller stick figure, and vice-versa.

Displaying the whole data set (or some part) in stick figures

You can opt to display either the whole data set of stick figures in a stick figure view at the

same time, or to display just the current stick figure, but with the trajectories of markers for

the entire data set being shown. You may wish to disperse the figures when using these

displays since a slow-moving subject will result in many super-imposed figures.

To display the data set:

Choose ‘Stick Figure Viewing Options...’ from the Views menu.
