# Heatmap The **Heatmap** shows how data points are distributed across two dimensions. The plot area is divided into *buckets* (grid cells), and each bucket is colored based on how many points fall into it. This makes clusters, gaps, and density patterns in the data easy to spot.
Heatmap
πŸ“Š **How to read it** (with default colors): * **Blue** = fewer points in a bucket * **Red** = more points in a bucket * Buckets between these extremes are shaded on a blue-to-red gradient. **Settings** Accessible via the βš™οΈ (settings wheel) in the top-right corner of the plot: * **X and Y axes** – Select which variables define the horizontal and vertical dimensions. * **Plot limits** – The limits on the x or y axes, or *auto* to take the min/max from the data * **Resample signals** – Relevant when your signals have different timestamps. See [Resampling](/docs/marple-insight/user-manuals/visualisation/resampling.md) for more details. * **Color range** – Change the lower and upper colors (default is blue–red) or the bucket count fraction. Buckets with fewer points than a specified fraction of the most populated bucket are shown in the lower color. Buckets with more points are shaded on a gradient up to the upper color. * **Opacity** – Opacity of the plot * **Filters** – Filter datapoints based on conditions ## Discover the Heatmap in 1 minute {% embed url="" %} Want to discover more Marple features in 1 minute?
