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.
By changing the input X and Y values to a percentage rather than pixel position, the self-setting canvas size can be leveraged properly. This matches how my company stores our touch-point data as well. For those who use integer pixel touch coordinates, since the must know the original image canvas size, they can perform a simple X /originalCanvasWidth type conversion for this new format to continue to apply.
