Required background

The following topics are prerequisites to understanding this topic:

  • igLinearGauge Overview: This topic provides conceptual information about the igLinearGauge control including its main features, minimum requirements, and user functionality.

Accessibility Compliance Reference

Introduction

All of the Ignite UI for jQuery™ controls and components comply with Section 508, Subpart 1194.22 of the Rehabilitation Act of 1973. The table below contains the specific rules of Subpart 1194.22 that pertain to the control. Also, detailed is how the igLinearGauge control complies with each of these rules.

In some cases, to meet the requirements of each accessibility rule, you may need to interact with the control by setting a specific property, but in other cases, the control performs these tasks for you.

Accessibility compliance reference summary

The following table summarizes the accessibility compliance features of igLinearGauge.

Rules Rule text How we comply
(a) A text equivalent for every non-text element shall be provided (e.g.,via "alt", "longdesc", or in element content). Since igLinearGauge is exclusively a graphic control, consider providing an alternative view for the disabled by converting the chart into a table or grid containing the chart data. This would allow using screen reader to assist users in getting the information from the chart.
(b) Equivalent alternatives for any multimedia presentation shall be synchronized with the presentation. See the note for (a) for an alternative way to provide compliance to the rule.
(c) Web pages shall be designed so that all information conveyed with color is also available without color, for example from context or markup. You can control coloring and provide suitable colors for the linear gauge using the styling and theming capabilities of the control.
(d)* Documents shall be organized so they are readable without requiring an associated style sheet. The control's markup may not be entirely readable without the associated style sheet due to igLinearGauge being client-side control and depending on CSS rules. See the note for (a) for an alternative way to provide compliance to the rule.
