WebFOCUS Online Help > Creating Charts With Graph Tools > Creating Graphs With Graph Assistant > Displaying Missing Data Values in a Graph

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:

• Graph as 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.
• Graph as gap. In all graph types (bar, line, or area), missing values appear as a gap in the graph.
• 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.
• Interpolated dotted line. 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.
