Null values in visualizations
                        Data is sometimes missing or cannot be calculated, because the fields contain values that are null or not a number (NaN). In the visualizations, null and NaN values are displayed in different ways, according to the following table.
| Null values in dimensions | NaN values in measures | |
|---|---|---|
| Bar chart | – | – ( when labels are enabled in the properties panel, otherwise empty) | 
| Combo chart | – | A combination of the NaN value for the bar and the line. | 
| Filter pane | No representation | N/A | 
| Gauge | N/A | – | 
| KPI | N/A | – | 
| Line chart | – | Empty | 
| Map | No representation | gray | 
| Pie chart | – | Empty | 
| Scatter plot | – | Empty |
