Use a chart widget to create a visual, easy-to-understand summary of the data. For example, a donut chart can show the distribution of opportunities across industry type. Because charts are interactive, dashboard viewers can select a segment of a chart to filter the results of other faceted widgets.
Wave supports multiple chart types. Each type has unique widget properties and step requirements. For details about each chart type, see Visualizing Data With Charts.
Unlike the explorer and classic designer, the Wave dashboard designer doesn’t support the following chart types: parallel coordinates, horizontal dot plot, vertical dot plot, and matrix. Although you can create a step with these chart types, the Wave dashboard designer converts them to a bar chart when added to a chart widget.
The selection in this widget filters the results of other widgets with faceted steps. You can configure this widget’s step to accept single or multiple selections, and specify whether the selections are optional or required. You can also set an initial selection that applies when the dashboard opens. While viewing the dashboard, you can undo the selection or change the selection to filter the results differently.
To enable this widget to filter other widgets, you must enable faceting on its step.
Drag the chart widget to the dashboard canvas.
To use an existing step for the widget, drag the step from the step panel and place on top of the widget.
If you don’t see the step panel, click the dashboard header to show it.
To create a step:
Click the button inside the widget to open the wizard.
The Select a Dataset screen appears, showing datasets in the most recently used order.
If you see a bar chart in the explorer instead, Wave selected the dataset that you used to create your previous widget step. To use a different dataset, close the explorer modal and click Create Step in the step panel.
Select the dataset on which you want to build the chart.
The explorer shows a bar chart with the Count of Rows measure.
Add measures that you want to show in the widget.
To add a measure, click . To change a measure, select the measure in the explorer and then choose a new one.
If needed, add groupings.
If needed, click Filter to filter the results.
You can add multiple filters.
Wave adds the step to the steps panel, making it available for use by other widgets in the dashboard. In addition, the widget shows the results in a bar chart.
To change the widget and step properties, click the widget.
The Widget panel groups the widget properties into sections. So that you don’t accidentally overlook some properties, note that some sections might be collapsed, by default. To expand or collapse a section, click the arrow next to the section header.
Set the widget properties to customize the appearance of the widget.
For example, select a different chart type in the Chart Type widget property. If the step requirements aren’t met for a chart type, you can’t select the chart type in a widget. For instance, some chart types require steps with only one measure.
To show and set the step properties, click Step in the panel.
You can configure this step to accept single or multiple selections, and specify whether the selections are optional or required.
To set the initial selections that are applied when a user opens the dashboard, click , and then click Pick Inital Filters.
You can make initial selections on any chart, date, list, toggle, or range widget. For example, you can select a bar in a bar chart and set that as the initial filter. If the underlying step for the bar chart is faceted, other widgets with faceted steps are also filtered based on this initial selection. While viewing the dashboard, the viewer can change the selection in the chart to filter the results differently or remove the filter altogether.
No selections are made in this widget when the user opens the dashboard unless you pick the initial filter. If the step is configured to require a selection, select the initial filter. Otherwise, the first value in the filter list is used.
