Heatmap customization (point, size, shadow)
You can customize your heatmaps using options from the "Customize heatmap" menu on the top.
You can zoom the heatmap in and out to get a better view:
You can choose if you want to see clicks, clicks and mouse movements or hide it all:
or, above all, change view options for gazepoints/fixations - point size, shadow size (blur), and opacity (color saturation of the points). Change it to make a heatmap easier to read and understand.
Point size:
Heatmap consists of many gazepoints/fixations. When you move a size slider, you can change the size of these points from 1 to 100 pixels. See how it works on a gif below (other sliders are set to 0 value).
Opacity:
The opacity slider changes the saturation of gazepoints/fixations colors. Thanks to this feature, you can increase the visibility of hot areas if needed.
NOTE: Colors don't indicate metric values!
Shadow:
The shadow slider enables you to change the blur of gazepoints making them a nice, smooth heatmap, not just a set of many colorful points.
You can also change the view between heatmap, view map and fog map.
