Enhance Geo Heatmaps with Interpolation

November 10, 2023
Highcharts Maps v11.2.0 adds support for geographic heatmap interpolation, allowing you to add estimated values between known data points for temperature map-like charts.

Highcharts Maps provides a standards-compliant method for creating schematic maps in web-based projects. It extends the user-friendly Highcharts JavaScript API to allow web developers to create interactive maps that display sales, election results, or any other geographically related information.

The Highchartts Maps v11.2.0 release adds support for interpolation in geographic heatmaps. The geoheatmap.interpolation feature allows the heatmap to render its data points as an interpolated image, estimating values between known data points. For example, you may have a have a table of temperature data that shows the temperature at specific points within a region. You can use interpolation to estimate the temperature in areas between the known data points. This new feature helps to create more easily understandable and visually appealing heatmaps, even with limited data sets.
