Example

  1. Add a Button control, and set its OnSelect property to this formula:
    Collect(Revenue, {Year:"2013", Europa:24000, Ganymede:22300, Callisto:21200}, {Year:"2014", Europa:26500, Ganymede:25700, Callisto:24700},{Year:"2014", Europa:27900, Ganymede:28300, Callisto:25600})

    Don't know how to add and configure a control?

  2. Press F5, click or tap the Button control, and then press Esc to return to the default workspace.

  3. Add a Column chart control or a Line chart control, set its Items property to Revenue, and set its NumberOfSeries property to 3.

    The control shows revenue data for each product over three years.

Accessibility guidelines

Color contrast

There must be adequate color contrast between:

  • each item in ItemColorSet
  • every item in ItemColorSet and the background color
  • Color and the background color

Screen reader support

  • There must be a Label immediately before the chart graphic to serve as the title.

  • Consider adding a summary of the chart graphic. For example, "The line chart shows a steady increase in sales between March and August this year."

    Note

    Chart graphics and Legend are hidden from screen reader users. As an alternative, a tabular form of the data is presented to them. They can also cycle through buttons that select data in the chart.

Low vision support

  • There must be a Legend if more than one series is shown.
  • Consider setting GridStyle to GridStyle.All, which shows both axes. This helps all users accurately determine the scale of the data.
  • For Column chart, consider setting Markers to true. This helps low-vision users determine the value of a column.

Keyboard support

  • TabIndex must be zero or greater so that keyboard users can navigate to it.

    Note

    When keyboard users navigate to the chart, they can cycle through buttons that select data in the chart.
