The PowerBI Heatmap Visual enables users to draw a heatmap overlay from a X, Y coordinate set on to an existing image. The user specify the image, and provide a data set of X, Y coordinates and optionally an intensity for each data point. The radius and the bluriness of the heatmap bubbles can be customized as well as the max value for the intensity.
I am using Heatmap with a test project to display the temperature in different parts of the building. This is a simple use-case (see attached screen-shot) but whatever I do, I don't see anything displayed on the map. Can anyone help?
