# Baselines ## Overview ChartSQL introduces baseline marks/lines to add context and reference points to chart visualizations. These lines represent significant values such as averages, min, max, median of a series. Baselines provide visual cues for comparison against a common or target value. See the [baselines](https://docs.chartsql.com/chartsql-studio/creating-charts/baselines "mention") documentation ## Baseline Examples
