Use this to set the attributes for plotting least significant intervals for a set of means.
Least significant intervals (LSIs) are used for comparing a set of predicted means graphically, especially when their SEDs differ. LSIs are intervals (or error bars) that are designed to overlap where there is no significant difference between estimates, and to be disjoint (i.e. not to overlap) where there are significant differences. This menu controls the titles, symbols and size of the labels used in the graph, and also allows you save or print the intervals. The LSIs are produced and plotted using the SEDLSI and LSIPLOT procedures.
This gives the title for the plot. If this field is left empty, a default title is used. To suppress the default title, use a single space in the field.
This gives the y-axis title for the plot. If this field is left empty, a default title is used. To suppress the default title, use a single space in the field.
Significance level (%)
This specifies the significance level as a percentage for the least significant intervals. It is the probability that two treatments intervals overlap under the null hypothesis that there is no difference between their means. The level must be between and 0 and 100%.
Display in intervals in output
Select this to display the intervals and the maximum discrepancy in the intervals in the Output window.
If this item is ticked, then the LSIs will be save in a pointer whose name is specified in the In: field. The pointer will contain 4 columns with suffixes of ‘Label’, ‘lowLSI’, ‘estimate’, and ‘upLSI’ giving the treatment labels, lower limit of the intervals, the treatment means and upper limit of the intervals respectively.

Symbols for means
These items let you control the size, shape and colour of symbols used to plot the means.
Lists the different symbols that you can use to represent the means in the graph. Select the type of symbol you want to use for the graph.
Lets you specify an amount by which the standard size of the symbols are to be multiplied. The value 1 represents the standard size. For example a value of 1.5 would increase the size of the symbol by 50% and a value of 0.5 would halve the symbol size. The Default setting will scale the symbol size according to the number of treatments in the graph. If the field is left empty the default setting will be used.
Lets you specify the colour of the symbol. Select the colour you want to use for the symbols in the graph.
Treatment labels size
This controls the size of the labels giving the treatment names on the x-axis of the graph. This is a size multiplier between 0 and 20. A value of 1 will give the standard label size. The Default setting will scale the label size according to the number of treatments in the graph. If the field is left empty the default setting will be used.
