We are using heatmap ESRI and customized it to have new field "score". Max score will be considered as MaxpixelIntensity of the heatmap. one case if we have point (a particular lat, lon) has high score, its representing as big circle with color configured in heatmap renderer ratio , also we had configured blurRadius is 20. what is the logic behind to show this big circle i.e occupying more space on the map. is it possible to control it ?
The above link has the details about that.
