Legend Options

A legend consists of items, such as lines, fill colors, and gradients. Each item has its own set of properties that can be changed using a right-click menu or the Legend Settings window.

To change legend settings or revert to initial settings, right-click to the right of the legend or on the title (if applicable). To undo recent changes to the legend, click Undo.

Tip: When you have both an overlay and a color variable, the color variable levels are shown by rounded color icons in the legend.

Legend Settings

Change certain aspects of the graphic elements (line, bars, and so on) such as color, fill, transparency, and gradient. You can also add a title to the legend. See Legend Settings Window.

Revert Legend

Returns the legend to its initial settings.

Move the Legend

To move the position of the legend, click the Graph Builder red triangle and select Legend Position. The legend appears on the right by default, but you can move it to the bottom of the graph, or inside the graph on the left or right.

To make the legend vertical or horizontal, change the Item Direction in the Legend Settings Window.

Legend Settings Window

Change aspects of the legend through the Legend Settings window.

Title

The name of the legend.

Check boxes

Shows or hides items in the legend. JMP hides items that appear to be redundant, but you can make them appear by selecting them. If your legend has a large number of entries, some might be hidden in the Graph Builder window to ensure sufficient space for the graph. However, all of the entries appear here, so you can select the ones that you want to show. To select or deselect all entries, right-click and select Toggle check box.

Up and down arrows

Changes the order of items in the legend.

Color Theme

Select a different color theme. For more information about color themes, see Create Color Themes in Using JMP.

Title Position

Places the legend title on top or to the left of the items in the legend.

Item Direction

Displays the legend horizontally or vertically.

Item Wrap

Sets the legend to be n items tall (if vertical) or n items wide (if horizontal).

Font

Changes the font type, style, and size.

Preview

Shows your changes to the legend.

OK

Commits your changes to the legend.

Cancel

Cancels your changes to the legend.

Opens the online Help.

Discrete or Continuous Legend Items

Legends can list discrete values or show a scale of continuous values:

Discrete legends can contain the levels of a categorical variable, or a list of variables.

Continuous legends describe a color intensity scale for a range of numerical values.

Right-click an item in either legend to see the following options:

Line Color

(Discrete legends only) Changes the color of the element associated with the item.

Marker

Changes the type of marker associated with the item.

Marker Size

Changes the size of the marker associated with the item.

Pattern or Style

Changes the fill or pattern of the element associated with the item.

Line Width

Changes the width of the line associated with the item.

Fill Color

Assigns a color for the contours.

Color by Theme

Colors multiple contours by levels in a color theme. This option sets line colors and fill colors for density contours.

Transparency

Changes the marker or label transparency. Enter the level of transparency to draw markers (points) on the graph. The degrees of opacity ranges from 0 (clear) to 1 (opaque).

Gradient

(Continuous legends only) Changes the gradient settings. See Gradient Settings.

Density Gradient

(Contour element only) Changes the gradient colors as follows:

Fade to White

The highest density contour uses the fill color, and colors fade to white at lower densities.

Fade to Gray

The highest density contour uses the fill color, and colors fade to gray at lower densities.

Full Color

Density contours use a predefined or customized color theme with full color control.

Gradient Transparency

(Contour element only) Changes the transparency of the gradient as follows:

None

Density contours use one transparency level for all levels.

Linear

Density contours get gradually more transparent at lower densities.

Revert

Restores default settings.

Gradient Settings

You can change various aspects of the gradient legend in the Gradient Settings window.

Figure 3.46 Gradient Settings Window 

To format the labels in the legend, use the menu, Width and Dec boxes, and the Use thousands separator (,) check box in the top left of the window.

Color Theme

Change the color theme or define a custom color theme. For more information about color options, see Create Color Themes in Using JMP.

Lightness Range

Set the range of intensities for the gradient coloring.

Number of Labels

Specify the number of labels for your legend. The value of zero provides the default number of labels.

Scale Type

Sets the scale for the gradient coloring. Look below the Maximum option for a description of the scale type.

Linear

The scale is piecewise linear between the Minimum and Center values and between the Center and Maximum values. This is the default scaling.

Quantile

The scale is piecewise linear for quantiles of the variable represented by the legend.

Standard Deviation

The legend range is divided into offsets from the mean determined by standard deviation increments. The scale is piecewise linear between these offset settings. The number of offsets is determined by the Number of Labels.

Log

The scale is linear for the logarithm of the values represented by the legend.

Log Offset

The scale is linear for the offset of the base 10 logarithm of the values represented by the legend.

Range Type

Sets the range of the legend values.

Default

Unless you specify values for the Minimum and Maximum, the minimum and maximum values include the range of the data and are chosen to be appropriately rounded values.

Exact Data Range

The minimum and maximum values are the exact minimum and maximum values for the data, or they are the values that you specify as Minimum and Maximum.

Middle 90%

The minimum and maximum values are the 5th and 95th quantiles, or they are the values that you specify as Minimum and Maximum. This option is resistant to outliers.

Minimum, Center, Maximum

Specify the smallest, middle, and largest values to use for your legend scaling.

Note: These values can override the Range Type values.

Horizontal

Changes the orientation of the legend to horizontal.

Reverse Colors

Reverses the colors in the color scheme.

Reverse Scale

Reverses the scale for the color theme.

Discrete Colors

Changes the color scheme from a continuous gradient to a stepped gradient with discrete colors.

Show Labels

Shows or hides labels for the legend.
