Zoom Path dialog

How to fill in the dialog box fields...

Fill in the dialog box fields as indicated below. You may also accept presented default values and options. Disregard grayed fields and options. When done, press Ok to continue. Or press Cancel to abort.

Time window
Use this radio button field to indicate how the value of offset [s] is to be interpreted:

• none = don't change the time window,
• all = show entire path and disregard offset [s],
• from begin = offset [s] is the time elapsed between the beginning of the trial and the beginning of the time window,
• from end = offset [s] is the time elapsed between the end of the time window and the end of the trial,
• timed = time window starts at GMT day time specified in the Reference time field.

duration [s]
Use this number field to indicate the duration of the time window to be displayed. The value will be adjusted automatically if it exceeds the duration of the trial. This field is unavailable if you select all in the Time window field.

offset [s]
Use this number field to indicate an offset for the time window to be displayed. The offset is between the ends of window and trial or between the beginnings of trial and window as indicated by the selection in the Time window field.

reference time
Use this time field to indicate the GMT day time when the time window should begin.

Zoom state
Use this radio button field to indicate the zoom state for the selected trials:

• none = don't change the zoom state,
• fit all = zoom out to show entire arena,
• fit paths = zoom in so the paths of all selected trials have the same magnification and the largest of them fills it's trial view entirely.,
• absolute = zoom to the magnification specified in the factor field,
• relative = change the magnification by the factor specified in the factor field.

factor
Use this number field to control zoom state changes. Its effect depends on the option selected in the Zoom state field. For fit all and fit paths, factor should be 100% or less and indicates the fraction of the trial view space to be used for displaying the data (e.g. 90% leaves a 5% free margin on each side). For absolute, factor indicates the magnification to zoom to (at 100% 1 workspace pixel equals one display pixel). For relative, factor indicates the relative magnification change (e.g. 200% = display 2x larger). This field is not available if you select none in the Zoom state field.

trial range
Use this range field to indicate the range of trials whose paths should be zoomed. If you selected a range of trials in the active case document before invoking the command, the field will display that range as default.

Note that...

With increased magnification, only those fields and path segments will be displayed which still fit entirely into the view frame. If you specify time windows using the Zoom Path command, this changes only the way paths are displayed and does not affect the path data itself, nor any analysis conducted with the data. If you wish to specify time windows for variables during path analysis you must add Window statements to the variable definition file.
There may not always be data points whose time stamps coincide exactly with the desired time window. Wintrack displays only data that fit entirely within the specified window, but the effectively displayed window may be smaller than the specified one. Specifically, the first point displayed is the one just after the latest point with a time stamp equal or later than the specified beginning of the window. The last point displayed is the latest point with a time stamp equal or earlier than the specified window end. The time stamp of a point always indicates the end of the time interval that is represented by that point. The very first point in each trial represents the time interval for 0 to its time stamp, and so on.
