9.5.1.3 The (Plot Details) Contour Labels Tab

This tab provides controls for customizing the format of the contour labels.

To control which levels are labeled in your contour graph, go to the Color Map/Contours Tab.
To control the display and format of the color scale level labels for color-filled graph, you need go to the Color Scale Control dialog.

Note: There are two buttons for labeling on Mini Toolbar buttons:

You can enable and customize contour lines labels using Show Contour Labels button
You can annotate the data points at max and min Z values using Annotate Min&Max Value button

5 Labeling Criteria

Font

Select a font from this drop-down list. Note that the default selection is controlled with the Default drop-down list on the Text Fonts tab of the Options dialog box.

Color

Select a color for contour label text.

Size

Type or select a size in this combination box. The size is in units of points.

White Out

Select this check box to display a white background behind each data label value.

Accent Buttons

Bold, Italic, and Underline buttons are provided.

Numeric Formats

Format	Specify the display format for the color map and contour levels from this drop-down list. Select between decimal, engineering, and scientific display. If you select one of the decimal formats, Origin uses a threshold for conversion to scientific notation. This threshold is controlled on the Numeric Format tab of the Options dialog box (Preferences: Options).
Divide by Factor	Type a value in this text box and all the color map and contour levels will be divided by this amount.
Decimal Places	Select this radio button to control the display of the number of digits after the decimal place. Select the desired value from the associated list box.
Significant Digits	Select this radio button to control the number of digits displayed. Select the desired value from the associated list box.
Prefix/Suffix	Type a value in one of these text boxes to append to the color map and contour level labels in the associated text boxes. These text boxes display in the graph. They do not, however, display in the level list on the Color Map/Contours tab. When typing value into one of these text boxes, you can use special formatting commands (referred to as "escape sequences") to control the font style (for example, superscript, subscript, and bold).

Repeat Labels

Specify whether to add multiple repeat labels on a contour line.

Distance Between Labels(%)

Specify how far between the repeat labels. The value entered in this option is in the unit of a percentage of the font size. This distance will also decide the amount of the repeat labels on one contour lines.

Align With Contour Line

Specify whether the contour line labels follow the flow of contour line. Note: The label rotation are preferred to the degree between 0~90, 270~360.

Curve Tolerance

Curve Tolerance is equal to the proportion of the distance along contour line to the straight line distance, between the end points of the contour label.

It decides the maximum amount of contour curvature allowed when placing labels on contour lines.

Labeling Criteria

The Min. Area (%) combination box can be used to set a percent value such that only contours that have a fraction of the total area larger than the set value will have a label associated with them.
