+# Scrolling Heatmap Aggregation
+
+![Scrolling Heatmap Aggregation](scrollingHeatmapAggregation-darkGold.png)
+
+This demo application belongs to the set of examples for LightningChart JS, data visualization library for JavaScript.
+
+LightningChart JS is entirely GPU accelerated and performance optimized charting library for presenting massive amounts of data. It offers an easy way of creating sophisticated and interactive charts and adding them to your website or web application.
+
+The demo can be used as an example or a seed project. Local execution requires the following steps:
+
+-   Make sure that relevant version of [Node.js](https://nodejs.org/en/download/) is installed
+-   Open the project folder in a terminal:
+
+          npm install              # fetches dependencies
+          npm start                # builds an application and starts the development server
+
+-   The application is available at _http://localhost:8080_ in your browser, webpack-dev-server provides hot reload functionality.
+
+
+## Description
+
+This example demonstrates **Scrolling Heatmap Aggregation** in `HeatmapScrollingGridSeries`. You can also configure aggregation for a static `HeatmapGridSeries`.
+
+By default, heatmaps display the closest heatmap cell value to each pixel that is rendered on the screen. With dense, high resolution heatmaps, this can mean that there is no guarantee which data value is displayed in a pixel.
+
+Heatmap aggregation can be enabled to specify this behavior (which value to show when multiple cell values are contained by single pixel) at the expense of a performance hit.
+
+In this example, the lower heatmap uses the `max` aggregation mode, making sudden **power spikes (shown in red)** much easier to identify in the data stream.
+
+# Heatmap Scrolling Grid Series aggregation
+
+In LightningChart JS, aggregation mode is configured with the `setAggregation` method. By default the aggregation mode is `undefined`. Bilinear interpolation is not supported simultaneously, so remember to disable it with `setIntensityInterpolation('disabled')`. 
+
+```js
+// Enable heatmap aggregation (max/min)
+heatmapSeries
+    .setAggregation('max')
+    // Bilinear interpolation is not supported simultaneously
+    .setIntensityInterpolation('disabled')
+```
+
+The data used in this example: [ElectroSense PSD Spectrum Dataset](https://doi.org/10.5281/zenodo.7521246).
