Workspace Node: 2D Pie Charts - Advanced Tab

In the 2D Pie Charts node dialog box, select the Advanced tab to display the following options.

Variables

    1. Click this button to display a variable selection dialog box.
    1. Select the variable(s) for the graph.

If you select more than one variable for the pie charts, a cascade of graphs (one for each selected variable) will display. The selection made will be displayed below the Variables button.

Graph type

Select the type of pie chart to be plotted from the Graph type list. Click a link below for a brief description of that type of graph.

Counts

Values

Regular

When Regular is selected and more than one variable is selected, a separate plot will be created for each variable.

Multiple

When Multiple is selected and more than one variable is selected, one plot will be created containing pie charts for each variable.

Frequency Intervals

These options are available when the Counts type of pie chart is selected (see above), which displays frequency data.

Use the options in this group box to specify a method of categorization for the selected variable(s). See Method of Categorization for more information.

Pie Legend

Select one of six formats for pie legends (Off, Percent, Values, Text labels, Text and percent, Text and values) to be placed in the graph.

  • If you select Counts as the graph type, selecting Text labels will use the category descriptions in the pie legend. Otherwise (for Values pie charts), the Text labels used will depend on the Pie labels (values) selected
  • If you select Case names as pie labels, the Text labels will display the actual case names instead of Case1, Case2, etc..
  • If you select a variable in the Pie labels option and then choose Text labels, Statistica will use the text labels of the selected variable in the pie legend).

Type

You can change the appearance of the pie by selecting either the two-dimensional (2D) or three-dimensional (3D) option button.
 See also the Plot: Pies topic (these options are located in the Graph Options dialog box).

Shape

The pie shape can be either elliptical (select Ellipse) or circular (select Circle).

However, selecting the Ellipse option button may cause the slices to be disproportionate in size (i.e., the slices that follow radii close to the vertical axis of the screen or paper will look relatively larger than their real size as compared to the horizontal slices which will be squeezed in perspective and will appear smaller).

See also the Plot: Pies topic (these options are located in the Graph Options dialog box).

Explode slice

Select this check box to explode a specified number of slices of the pie,

See also the  Plot: Pies topic (these options are located in the Graph Options dialog box) for more details.

Pie Labels (Values)

You can label the pie with Case Names (select any of the Text options in the Pie Legend list) or values (text or numeric depending on the setting in the Pie legend list) of a specified variable.

If you do not want any pie labels, select Off.

Options / C / W

See Common Options.

OK

Click this button to accept all the specifications made in the dialog box and to close it.

The results are placed in the Reporting Documents node after running (updating) the project.
