Bottom Scale Properties

Note: This dialog is not applicable to and therefore unavailable for Pie graphs.

This dialog controls scale properties along the x-axis (or y-axis in the case of Horizontal Bar graphs) of the currently selected graph object. It is accessed by selecting a graph amd then selecting Properties > Bottom Scale Properties (or Left Scale Properties for Horizontal Bar graphs).

X-Y Plot and Horizontal Bar graphs use the Value Scale Properties dialog for what appears to be the bottom scale. Refer to "Value Scale Properties" in Chapter A for information on modifying the bottom scale for these graph types.

This scale is also known as the "Category Scale," since each discrete point along it represents a category of data.

Tick Marks

This pane controls tick marks for the currently selected graph's bottom scale.

Show Tick Marks

If checked, tick marks will be shown between each scale label along the bottom of the graph. You can set the following options for these marks:

Position

You can position tick marks in the following locations:
Outside
The mark will appear outside of the graph's grid area.
Inside
The mark will appear inside of the graph's grid area.
Cross
The mark will appear both outside and inside of the graph area so that it looks like a cross.

Size

The mark can appear in one of three sizes: Small, Medium, or Large.

Color

The color button will launch a Color Properties dialog, where you can change the color used for bottom scale tick marks. For more information about this dialog, refer to "Color Properties" in Chapter A.

Label

This dialog pane allows you to change the settings for scale labels.

Display Scale Labels

If checked, scale labels will be displayed for each category that is being graphed.

Limit Label Character Length

Limits the character length of each scale (category) label to the specified number. If the label is longer, it will truncate it and add a period on the end. This period counts as part of the character length.

Max Length Horizontal Text
Sets the maximum number of characters in the category label when it is not rotated.
Max Length Rotated Text
Sets the maximum number of characters in the category label when it is rotated.

First Label to be Displayed

This specifies the number of the first bottom scale label that will actually be shown.

Perform the Following Adjustments

Allows you to select how the following category label adjustments are applied. The options are As Needed and Always. For a description of how these options behave, refer to "Scale Label Adjustments" in Chapter 1.

Wrap Text To Max Number of Lines
When selected, the text in the scale label will be wrapped to the specified number of lines (if needed).
Shrink Font To
This rule applies only when As Needed has been selected. If this rule is applied, PopChart will attempt to shrink the font of the scale labels down to the font point size specified in the box to the right of this option.
Stagger Labels
This rule applies only when As Needed has been selected. If this rule is applied, PopChart will attempt to stagger the labels so that every other one appears on an alternate level.
Rotate Labels
If this rule is applied, PopChart will rotate the scale labels by the specified number of degrees. This will usually significantly decrease the vertical size of the graph, unless Limit Label Character Length has been enabled or Keep Text and Ticks Within Graph Bounds has been unchecked in the Graph Properties > General dialog pane (refer to "Keep Text and Ticks Within Graph Bounds").
Skip x Labels At a Time
This rule specifies that a certain number of labels should be skipped altogether. The bar, line, area, or plot point will still be shown for that category, but the scale label will not. The graph will use the number in the box to determine the increment between each shown bottom label. For example, if the value is 1, it will display every other label. If the value is 2, it will display every third label. If the value is 0, it will skip nothing.

Font

Specifies font characteristics for the bottom scale. For more information, refer to "Font Properties".
