Pie Attributes Dialog Box (WzPie)

This dialog box is used to set attributes for the Pie Attributes include fill colors, legend position, text size and others.

Outline Color—Specifies the color of the outline around pie slices and legend items.

Draw Shadow—If selected, a drop-down shadow is drawn under the pie chart.

Shadow Color—If Draw Shadow is selected, this function specifies the shadow color.

Offset Shadow—If Draw Shadow is selected, this function specifies the offset of the shadow in centimeters.

Slice Start Angle—A floating point value specifying the angle, in degrees clockwise from the vertical, where to start drawing the first slice (the slice represented by the first element of the input data array). By default, the slice angle is zero (vertical).

Reverse Slice Direction—If selected, slices are drawn in counterclockwise order rather than in the default direction, clockwise.

Character Size—Specifies the size of the pie labels and legend text. A value of 1 is the default size. A value of 2 produces text twice as big.

Show Legend—When selected, a Pie legend is displayed. The legend consists of a small boxes that correspond to Pies. The legend boxes are filled with the same color as their corresponding Pies.

Show Legend Text—When selected, each legend box includes descriptive text. By default, this text is the number of the associated Pie {0 .. n–1}. If a Labels Var is specified, the elements of the specified variable are used as labels.

Draw Legend Box—When selected, a box is drawn around the legend.

Text Color—Specifies the color of the legend text.

Legend Position—Pick the location of the legend.

Label Variable—This field lets you enter the name of a variable containing numerical values or strings that you wish to use as legend text. If this field is blank, the default legend labeling is used.

note	The specified variable must exist on the $MAIN$ level; it must have the same number of elements as the number of Pies; and it must be a 1D variable.

Draw Patterns—If this button is selected, all slices are filled with patterns. The Pattern functions, described below, are used to customize the patterns of the individual slices.

Pattern Colors—Specifies the color used for pattern lines. If Draw Patterns is selected, the color specified here is the color used for the pattern lines. If Draw Patterns is not selected, this color is used to fill the specified slices with solid color.

Pattern Background—Specifies the background color used to fill individual Pies. This function is only enabled when Draw Patterns is selected.

Pattern Linestyle—Specifies the linestyle for pattern lines. This function is only enabled when Draw Patterns is selected.

Pattern Orientation—Specifies the orientation of the pattern lines in degrees of rotation clockwise. By default, lines are drawn horizontally (0 degrees). This function is only enabled when Draw Patterns is selected.

Pattern Spacing—Specifies the space, in centimeters, between the pattern lines. This function is only enabled when Draw Patterns is selected.

Pattern Thickness—Specifies the thickness, in pixels, of the pattern lines. If This function is only enabled when Draw Patterns is selected.

Explode—Specifies that the selected slice should be “exploded”, or drawn slightly offset from the other slices.

Offset Explode—Specifies how far, in centimeters, exploded slices are to be separated from the other slices.

Label Style—Pick the type of label to display on the slices. Percent Labels represent the percent of each slice relative to the total pie. Value Labels represent the actual value of the slice. No Labels turns off this feature.

Character Thickness—Specifies the thickness of the label text.

This lets you chose the slice that you wish to apply fill and pattern changes to. For instance, if you display a chart containing five slices, this list will include five elements, numbered from {0..n–1}. Simply click on a slice number to select it. Any changes that you make to the Slice Pattern Attributes will apply to the selected slice, or slices. To select multiple slices, press and drag the left mouse button across the slices you wish to select, or, shift click to select multiple slices.
