Histogram and Heat Map Queries

This tutorial covers how to generate a histogram or heat map chart in Insights using the NRQL histogram function. A histogram chart is a graphical representation of the distribution of data - each bar represents a bucket or grouping of data for the value of that attribute and the height of the bar shows the frequency events occurred in that particular grouping. The heat map adds to the histogram chart using color to show the frequency of the intersection of two attributes.
