Linear Scale

Component Palette Icon

The Linear Scale component has two main purposes. The first is to display a series of tick marks and labels that visually represent a linear range between a minimum value and a maximum value. The second purpose is to display indicators that represent a value or range of values, correctly positioned on the linear scale.

To configure the indicators, use the Linear Scale Customizer which is described below. To configure the tick marks, use the Linear Scale's various properties in the Property Editor that determine the minimum value, maximum value, and the various tick mark spans.

Note that there is no tall/wide option for this component. This is based on the width/height of the component. A tall Linear Scale has tick marks on the left or right, and a wide component has tick marks on the top or bottom.

Customizers

The Linear Scale component has a special customizer called the Linear Scale Customizer. The customizer is where you configure the indicators that visually represent how your data is displayed on the scale. You can choose from several indicator styles: Arrow, Line, Range, and Wedge. There are a number of properties available to customize the appearance of your data on the Linear Scale. Not all Linear Scale Customizer properties are available with all indicator styles. The property will be grayed out if it is not available for that particular indicator. Use the preview window to validate the style you want to use for your data.

To make your indicator values dynamic, you can use a Cell Update binding on the Indicators property of this component.

Linear Scale Customizer - Property Descriptions

Property	Description
Indicator Style	There are four indicator styles to choose from: Arrow, Line, Range, and Wedge. Arrow: A line with an arrow head at the given value Line: A basic flat line at the given value Range: a rectangle displayed with the given value at the bottom and a height equal to the Extent Wedge: a wedge shape centered on the given value and a height equal to the Extent
Value	The position of the indicator.
Extent	Overall thickness of the indicator. Not valid for a Line style.
Length	The number of pixels to draw the indicator starting at the component edge.
Width	Thickness of the line in the indicator. Only valid for Arrow and Line styles.
Label	Name displayed next to the indicator.
Label Angle	The angle of the label specified in degrees.
Color	Color of the indicator.
Label Color	Color of the indicator Label.

Examples

In this example, the Linear Scale displays indicators for high and low levels. A Cell Update Binding was used on an Arrow indicator to make the "Current" level value dynamic.
