Case Uses & Industries

SciChart JavaScript heatmaps are an ideal option to display Sonar, MRI/histopathology images of vital signs, Spectrograms or Audio/Radio analysis. The speed of heatmap visualization can decrease the time to diagnosis, helping you provide a better service for your patients while also creating a more efficient workflow for your health professionals.

SciChart’s JavaScript heatmaps are also effective tools for ground engineers as they can access clear visuals to inform them whether the ground is suitable for digging or not.

It’s also an effective tool for marketers and website owners, as heatmaps can easily show how users are interacting with their website, identifying areas that have lots of conversions, and those that don’t.

Uniform heat maps are extremely fast, lightweight series types for rendering two dimensional data as a heatmap.

Heatmaps rely on color to communicate values and when handling large volumes of data, colors are much easier to read than raw numbers. With SciChart, we support large JavaScript heatmaps (1000×1000 or more) and custom color maps help you stay on brand and create a map that works for your audience and purpose.
