How to: Add Empty Points to the Chart

How to: Add Empty Points to the Chart

Null values are shown on the chart as empty spaces or gaps between data points in a series. Empty points are data points that can be inserted in the empty space created by null values.

By default, empty points are calculated by taking the average of the previous and next data points that contain a value. You can change this so that all empty points are inserted at zero.

To remove null values from a series, modify the dataset query or add a filter to groups on the chart. For more information, see Preparing Data for Display in a Chart Data Region and Filtering Data in a Report.

In Shape chart types, null values are omitted.

To specify empty points on a chart

  1. Open the Properties pane.

  2. On the design surface, right-click the series that contains null values. The properties for the series are displayed in the Properties pane.

  3. Expand the EmptyPoint node.

  4. Select a color value for the Color property.

  5. In the EmptyPoint node, expand the Marker node.

  6. Select a marker type for the MarkerType property.

    NoteNote

    You must select a marker type to add empty points to a bar, column or scatter chart. However, for area, line and radar charts, selecting a marker type is optional because the chart fills in the empty space or gap without requiring a marker to be specified.

  7. Set the value of the empty point.

    1. In the Properties pane, expand the CustomAttributes node.

    2. Set the EmptyPointValue property. To insert empty points at an average of the previous and next data points, select Average. To insert empty points at zero, select Zero.
