The real-time heatmap chart is used to visualize normalized histogram data over time. It works by first sorting incoming histograms into a small set of discrete buckets. For multi-series data it uses color blending to show series concentration. This type of chart has the most "intense" data format, with each entry expecting a sparse histogram.
