You can set additional options by clicking the Options tab.
Data arrangement
Specifies the form of the data to be used in the plot. You can supply the data as a List of variates or a Variate with time factor.
Available data
This lists data structures appropriate to the current input field. It lists the factors or variates for specifying the data. The contents will change as you move from one field to the next. Double-click a name to copy it to the current input field or type the name.
List of variates
Data variates for successive time points
Specifies the data at successive time points which are to be plotted. Each variate must contain the measurements made on a set of units at one of the occasions on which they were observed. Double-click a name in the Available data field to copy it across or type the name. You can transfer multiple selections from Available data by holding the Ctrl key on your keyboard while selecting items, then click to move them all across in one action.
List of time points
Specifies the time points along the x-axes of the graph. The number of time points must be equal to the number of data variates selected for the Data variates for successive time points. You can either type the time points in directly using either a comma or space to separate each time point or select the name of an identifier containing the values from the list of Available data.
Variate with time factor
Data variate
Specifies the data observations in stacked format where the times of each observation is specified within an associated factor
Time factor
Specifies a factor containing the time points for the observations in the data variate.
Groups on same screen
A factor specifying the grouping of the subjects where the means of the observations at each level of the factor are plotted in the graph. Double-click a name in the Available data field to copy it across or type the name.
