--- title: Connect null values --- ### Connect null values Choose how null values, which are gaps in the data, appear on the graph. Null values can be connected to form a continuous line or set to a threshold above which gaps in the data are no longer connected. - **Never** - Time series data points with gaps in the data are never connected. - **Always** - Time series data points with gaps in the data are always connected. - **Threshold** - Specify a threshold above which gaps in the data are no longer connected. This can be useful when the connected gaps in the data are of a known size and/or within a known range, and gaps outside this range should no longer be connected.
