Power BI Desktop 报表中的辅助功能Accessibility in Power BI Desktop reports

Power BI Desktop 具有使残疾人士能够更轻松地使用 Power BI Desktop 报表并与之进行交互的功能。Power BI Desktop has features that enable people with disabilities to more easily consume and interact with Power BI Desktop reports. 这些功能包括通过键盘或屏幕阅读器使用报表、通过按 Tab 键将焦点移动到页面中的各个对象以及在可视化效果中方便地使用标记。These features include the ability to consume a report using the keyboard or a screen reader, tabbing to focus on various objects on a page, and thoughtful use of markers in visualizations.



这些辅助功能在 2017 年 6 月 Power BI Desktop 和更高版本中可用。These accessibility features are available with the June 2017 Power BI Desktop and later releases. 我们也为将来的版本规划了其他辅助功能。Additional accessibility functionality is planned for future releases as well.

可以使用 Ctrl+F6 在报表页选项卡或在给定的报表页中的对象之间切换焦点。You can switch focus between the report page tabs, or objects on a given report page, using Ctrl+F6.

  • 当焦点位于报表页选项卡上时,使用 Tab 或箭头键将焦点从一个报表页移到下一个报表页。When focus is on report page tabs, use the Tab or Arrow keys to move focus from one report page to the next. 无论当前是否被选中,屏幕阅读器都会读出报表页的标题。The title of the report page, and whether it is currently selected, is read out by the screen reader. 若要加载当前焦点所在的报表页,使用 Enter 或空格键。To load the report page currently under focus, use the Enter or Space key.
  • 当焦点位于已加载的报表页上时,使用 Tab 键将焦点转移到页面上的每个对象,其中包括所有文本框、图像、形状和图表。When focus is on a loaded report page, use the Tab key to shift focus to each object on the page, which includes all textboxes, images, shapes, and charts. 屏幕阅读器读取对象的类型及其作者提供的该对象的说明。The screen reader reads the type of object, and a description of that object that's provided by its author.

创建可访问报表的提示Tips for creating accessible reports

以下提示可帮助你创建更易于访问的 Power BI Desktop 报表。The following tips can help you create Power BI Desktop reports that are more accessible.

  • 对于“行”、“区域”、“组合图”、“散点图”和“气泡”视觉对象,请启用标记,并对每行使用不同的标记形状。For Line, Area, and Combo visuals, as well as for Scatter and Bubble visuals, turn markers on, and use a different Marker shape for each line.

    • 若要启用“标记”,可在“可视化效果”窗格中选择“格式”部分,展开“形状”部分,然后向下滚动查找“标记”切换,并将其切换为“开”。To turn Markers on, select the Format section in the Visualizations pane, expand the Shapes section, then scroll down to find the Markers toggle and turn it to On.
    • 然后,从“形状”部分中的下拉列表框中选择每行(如果使用区域图表,则为区域)的名称。Then, select the name of each line (or area, if using an Area chart) from the drop-down box in that Shapes section. 在下拉列表下方,可以调整用于所选行的标记的许多方面,包括其形状、颜色和大小。Below the drop-down, you can then adjust many aspects of the marker used for the selected line, including its shape, color, and size.


    • 对每行使用不同的标记形状可使报表使用者更容易区分行(或区域)。Using a different Marker shape for each line makes it easier for report consumers to differentiate lines (or areas) from each other.
  • 作为上一个项目符号的后续内容,不要依赖颜色传达信息。As a follow on to the previous bullet, don't rely on color to convey information. 使用行上的形状(标记,如上一项目符号中所述)很有帮助。Using shapes on lines (markers, as described in the previous bullets) is helpful.
  • 从主题库中选择一个高对比度、适合色盲人士的主题,然后使用主题预览功能将其导入。Select a theme that is high contrast and color blind friendly from the theme gallery, and import it using the Theming preview feature.
  • 为报表上的每个对象提供替换文字。For every object on a report, provide Alt Text. 这可确保报表使用者了解你想通过视觉对象表达的内容,即使他们看不见视觉对象、图像、形状或文本框。Doing so ensures that consumers of your report understand what you are trying to communicate with a visual, even if they cannot see the visual, image, shape, or textbox. 在“可视化效果”窗格中选中对象(例如视觉对象、形状等),选择“格式”部分,展开“常规”,然后滚动到底部并填写“替换文字”文本框,可为 Power BI Desktop 报表上的任何对象提供“替换文字”。You can provide Alt Text for any object on a Power BI Desktop report by selecting the object (such as a visual, shape, etc.) and in the Visualizations pane, select the Format section, expand General, then scroll to the bottom and fill in the Alt Text textbox.


  • 请确保报表在文本和任意背景颜色之间有足够的对比度。Make sure your reports have sufficient contrast between text and any background colors.
  • 使用易于阅读的文本大小和字体。Use text sizes and fonts that are easily readable. 文本太小或难以阅读的字体对辅助功能没有任何帮助。Small text size, or fonts that might be difficult to read, are unhelpful for accessibility.
  • 包括所有视觉对象中的标题、轴标签和数据标签。Include a title, axis labels, and data labels in all visuals.

注意事项和限制Considerations and limitations

辅助功能存在一些已知问题和限制,如以下列表所述:There are a few known issues and limitations to the accessibility features, described in the following list:

  • 在 Power BI 服务中查看的报表(包括任何嵌入的报表)支持 JAWS。JAWS is supported in reports that are viewed in the Power BI service, including any embedded reports. 虽然 Power BI Desktop 也支持 JAWS,但在打开任何 Power BI Desktop 文件前,必须先打开屏幕阅读器,这样屏幕阅读功能才能正常发挥作用。JAWS is also supported in Power BI Desktop, however you must open the screen reader before opening any Power BI Desktop files, in order for screen reading to work properly.
