- **Points -** Display points for values.
- **Point radius -** Controls how large the points are.
### Stacking and null value
- **Stack -** Each series is stacked on top of another.
- **Percent -** Available when **Stack** is selected. Each series is drawn as a percentage of the total of all series.
- **Null value -** How null values are displayed. _This is a very important setting._ See note below.
- **connected -** If there is a gap in the series, meaning a null value or values, then the line will skip the gap and connect to the next non-null value.
- **null -** (default) If there is a gap in the series, meaning a null value, then the line in the graph will be broken and show the gap.
- **null as zero -** If there is a gap in the series, meaning a null value, then it will be displayed as a zero value in the graph panel.
> **Note:** If you are monitoring a server's CPU load and the load reaches 100%, then the server will lock up and the agent sending statistics will not be able to collect the load statistic. This leads to a gap in the metrics and having the default as _null_ means Grafana will show the gaps and indicate that something is wrong. If this is set to _connected_, then it would be easy to miss this signal.

## Series overrides
Series overrides allow a series in a graph panel to be rendered differently from the others. You can customize display options on a per-series bases or by using regex rules. For example, one series can have a thicker line width to make it stand out or be moved to the right Y-axis.
