The Status history visualization shows periodic states over time. Each field or series is rendered as a horizontal row. Boxes are rendered and centered around each value.
Status history visualization works with string, boolean and numerical fields or time series. A time field is required. You can use value mappings to color strings or assign text values to numerical ranges.
When the legend option is enabled it can show either the value mappings or the threshold brackets. To show the value mappings in the legend, it's important that the `Color scheme` as referenced in [Apply color to a series and fields]({{< relref "../panels/working-with-panels/apply-color-to-series/" >}}) is set to `Single color` or `Classic palette`. To see the threshold brackets in the legend set the `Color scheme` to `From thresholds`.
