[. . . ] These selections change the way summary information is displayed in the chart. You can display the key and determine the alignment and location of the key title. Dots and Lines: Labels Figure 8-6 Dots and Lines: Labels tab Point Labels. Category, percentage, and count labels can be displayed for lines. You can specify the position of the labels with respect to the points or lines. 124 Chap te r 8 Dots and Lines: Drop Lines Figure 8-7 Dots and Lines: Drop Lines tab On a multiple-line chart, drop lines connect the points in each category across lines. Drop lines are not available when a scale variable is on the independent axis. 125 Line, Dot, and Ribbon Charts Dots and Lines: Ribbon Width Figure 8-8 Dots and Lines: Ribbon Width tab For three-dimensional line or ribbon charts, you can change the width of the ribbons. To Change Line, Dot, or Ribbon Properties A line or ribbon or dot set, or a selection of several lines or ribbons and dot sets, have properties that can be changed, as long as the property is not controlled by the data. Select one or more lines, ribbons, or dot sets in a line, ribbon, or dot chart. 126 Chap te r 8 From the menus choose: Edit Line Properties or Right-click a line, dot, or ribbon (or selected group), and choose Properties from the context menu. Optionally, you can: n n Change the line appearance and dot appearance. Change line labels and dot labels. Dot and Line Properties Figure 8-9 Dot and Line Properties dialog box 127 Line, Dot, and Ribbon Charts The properties listed here apply only to the lines, ribbons, or dot sets that are currently selected. A dot set consists of all of the dots that fall on the same line, whether or not the line is displayed. Dots. Also, labels can be displayed that show the number of cases used to calculate the value for each point or the percentage. Displays the percentage or count of cases represented by the line, as well as the category. To Change Point Label Properties Select one or more dot labels. From the menus choose: Edit Line Properties or Right-click a dot label and select Properties from the context menu. Change the location, connector, and color of the labels. 128 Chap te r 8 Point Label Properties Figure 8-10 Point Label Properties dialog box The properties listed here apply only to dot labels that are currently selected. Value, Percent, Count. The color of the selected labels can be changed. Chapter Pie Charts 9 What proportion does each group contribute to the total?Each slice of the pie belongs to a group defined by a category of a variable. The size of a slice is proportional to the frequency (count) of its group or to a function of a summary variable. For example, one pie chart shows the number of employees in each department, making it easy to compare relative department sizes. In another pie, each slice shows the sum of sales for individuals in a group. To compare separate categories, pie charts can be displayed separately in panels or stacked in a cluster. In a cluster, pies of different diameters are stacked to make comparison of slices easy. In another type of display, plotted pies, you can plot pies for subgroups defined by combinations of categories, using Cartesian coordinates (x and y axes) with a pie at each intersection of categories.

Create Simple Pie Chart: Assign Variables Figure 9-1 Create Simple Pie Chart: Assign Variables tab A simple pie chart summarizes categories defined by a single variable or by a group of related variables. For each category, the size of each slice represents the count, the percentage, or a summary function of a variable. Selecting this effect from the drop-down list gives the pie depth. 132 Chap te r 9 To Create a Simple Pie Chart Sliced by a Categorical Variable Drag a categorical variable to Slice By. [. . . ] By using the Browse button on Textures, you can insert any bitmap file as a texture. The bitmap should be square and sized to a number of pixels equal to a power of 2 (for example, 64 by 64 or 128 by 128). Otherwise, the program will clip the bitmap to the nearest lower power of 2. To Change Fill Styles Activate the chart (double-click it). When the Fill palette is displayed: Select the effect (pattern, gradient, or texture). [. . . ]
