Configuring the Background (igBulletGraph)

Topic Overview

Purpose

This topic explains, with code examples, how to configure a background for the bullet graph. This includes setting the background’s size, position, color, and border.

Required background

The following topics are prerequisites to understanding this topic:

igBulletGraph Overview: This topic provides conceptual information about the igBulletGraph™ control including its main features, minimum requirements, and user functionality.
Adding igBulletGraph: This is a group of topics demonstrating how to add the igBulletGraph control to an HTML page and to an ASP.NET MVC application.

Configuring the Background

Background configuration summary

The background of the igBulletGraph control is configurable in terms of spread and position and look-and-feel (fill and border). The spread and position are configurable in the dimension across the scale (through the backingInnerExtent and backingOuterExtent properties); along the scale, the background always spreads from one edge of the control to the other. The fill color and the border are managed by a set of properties available in the style template.

The following picture demonstrates a background color of a variety of orange and a cyan border with a thickness of 3 pixels. The background extent is made smaller by providing values for its backingInnerExtent and backingOuterExtent properties.

Background configuration summary chart

The following table explains briefly the configurable aspects of igBulletGraph control’s background and maps them to properties that configure them.

Configurable aspects		Property	Default value
Spread and position (across the scale)		backingInnerExtent	0
Spread and position (across the scale)		backingOuterExtent	1.0
Look-and-feel	Fill color	backingBrush	Defined in the default theme
	Border color	backingOutline	Defined in the default theme
	Border thickness	backingStrokeThickness	2.0

Property settings

The following table maps the desired behavior to its respective property settings.

In order to configure:			Use this property:	And set it to:
Aspect		Details	Use this property:	And set it to:
Spread and position (across the scale)	Bottom / left edge position	The position of lower edge of the background (at horizontal orientation) or the left edge (at vertical orientation) relative to the bottom edge of the Graph area at horizontal orientation or to its left edge – at vertical orientation.	backingInnerExtent	The desired value as a relative part of the height/width of the Graph area (depending on the orientation) presented as a fraction of 1 (e.g. 0.2)
Spread and position (across the scale)	Top / right edge position	The position of top edge of the background at horizontal orientation or the right edge at vertical orientation relative to the lower edge of the Graph area at horizontal orientation or to its left edge – at vertical orientation.	backingOuterExtent	The desired value as a relative part of the height/width of the Graph area (depending on the orientation) presented as a fraction of 1 (e.g. 0.2)
Look-and-feel	Fill color	Fill color of the background	backingBrush	The desired color
	Border thickness	Border thickness of the background	backingStrokeThickness	The desired value in pixels
	Border color	Border color of the background	backingOutline	The desired color

Example

The screenshot below demonstrates how the igBulletGraph looks as a result of the following settings:

Property	Value
backingBrush	'#FFDAB9'
backingOutline	'#00FFFF'
backingStrokeThickness	“3”
backingInnerExtent	“0.2”
backingOuterExtent	“0.7”

Following is the code that implements this example.

In JavaScript:

 $(function () {             
    $("#bulletGraph").igBulletGraph({
        width: "300px",
        height: "100px",
        backingBrush:'#FFDAB9',
        backingOutline: '#00FFFF',
        backingStrokeThickness: "3",
        backingInnerExtent:"0.2",
        backingOuterExtent:"0.7"
  });
