| Variables
|
Click this button to display a variable selection dialog box, in which you select the variable(s) to be plotted. The selection that you make is then displayed in the area of the dialog box below the
Variables button. When you select more than one variable for the regular scatterplot, a sequence of graphs is produced (one for each of the variables).

| Intervals for X-Histogram/Intervals for Y-Histogram
|
Use the options in these group boxes to specify a method of categorization of the values for each of the component histograms. Categorization (or Intervals) is used in two classes of graphs in STATISTICA: categorized graphs and graphs that include grouping or categorized variables. You can choose from several methods of categorization:
- Integer mode
- Unique values
- Boundaries
- Categories
- Codes
Note: You can change the number of significant digits that are used when labeling the category levels in the graph by specifying the desired number of digits in the No. of decimals option on the Axis Scale Values
tab of the Graph Options dialog box. You can also specify alphanumeric category labels or the equivalent numeric category labels on the graph axes by using the Display text labels as axis values option. Note that you can define up to 1,000 grouping (or categorized) variables in STATISTICA.
|
| Histogram size
|
Use the
Histogram size box to adjust the size of the component histogram with respect to the size of the graph window (e.g., 30% of the graph window size). Note that the size of the scatterplot will adjust accordingly.

|
| Scatterplot fit
|
The options in the
Scatterplot fit group box apply only to the scatterplot component graph. You can fit either none (select
Off) or one of several equations to the data in the scatterplot by selecting one of the predefined functions in this box.
 Linear
 Polynomial
 Logarithmic
 Exponential
 Distance Weighted Least Squares
 Negative Exponential Weighted Least Squares
 Spline
 Lowess

| Histogram fit
|
You can superimpose a distribution over the histograms. Select the type of distribution to fit from this list. For more details on fit types, see Fitted Functions for Histograms.
|
| Breaks between columns
|
Select this check box if you want the histogram columns to be separated from each other. According to common convention, histograms of continuous variables should be displayed with no breaks (the breaks signify discrete values).
|
|
|
| Histogram statistics
|
You can include a variety of statistics as footnotes in the graph by selecting one or more of the statistics in this group box.
|
| Total count
|
Select this check box to include the total count or number of cases used in creating the histogram.
|
| Shapiro-Wilk test
|
Select this check box to include the Shapiro-Wilk W statistics for normality and its associated
p-value.
|
| Descriptive statistics
|
Select this check box to include a variety of descriptive statistics including the total count, mean, and standard deviation as well as the minimum and maximum values.
|
| Kolmogorov-Smirnov test
|
Select this check box to include the Kolmogorov-Smirnov
d statistics (for normality), its associated
p-value and the Lilliefors statistic.
|
|
|
| Scatterplot statistics
|
You can include a variety of statistics as footnotes in the graph by selecting one or more of the statistics listed in this box.
|
| R square
|
Select this check box to include the R-square for the plotted variables.
|
| Correlation and p
|
Select this check box to include the correlation for the plotted variables and its corresponding
p-value.
|
| Regression equation
|
Select this check box to include the regression equation in the plot.
