Display Missing Values in a Graph

Reference:

You can display missing data values (in a bar graph, line graph, area graph, or any variation of these graph types) in one of the following formats:

Skip (leave gaps). In all graph types (bar, line, or area), missing values appear as a gap in the graph.
Display At Zero. In bar graphs, a bar appears on the zero line. In line graphs, a solid line connects the missing value with the succeeding value. In area graphs, the area appears on the zero line.
Interpolate. In a line graph, missing values appear as an interpolated dotted line that connects the plot points immediately preceding and succeeding the missing value. In bar and area graphs, missing values display as an interpolated (transparent) bar or area.

Dotted line to zero. In line graphs, a dotted line connects the missing value with the succeeding value. In 3D bar graphs, solid lines outline the flat bar corresponding to the missing value. In 2D bar graphs, a gap appears in the graph. In area graphs, a transparent area extends down to the zero line and then up to the succeeding value.

Procedure: How to Display Missing Values in a Graph

Click the Chart editor tab.

Scroll to the bottom of the Chart objects area.

In the Advanced folder, click the Data handling form.
The Data handling form appears below the graph preview area.

Click the down-arrow to open the drop-down list.

Select one of the following methods of displaying missing values:
- Skip (leave gaps)
- Display At Zero
- Interpolate
The selected method to display missing values is now applied to your graph. If any missing values exist in the graph you are creating, your selection is reflected in the graph preview area.
