Heatmaps are used to show relationships between two variables, one plotted on each axis. By observing how cell colors change across each axis, you can observe if there are any patterns in value for one or both variables.

What graph is best for density?

histograms

Density Plot



An advantage density plots have over histograms is that they’re better at determining the distribution shape because they’re not affected by the number of bins used (each bar used in a typical histogram). Density plots are used to study the distribution of one or a few variables.

What is a spatial heatmap?

Types. There are two main type of heat maps: spatial, and grid. A spatial heat map displays the magnitude of a spatial phenomena as color, usually cast over a map. In the image labeled “Spatial Heat Map Example,” temperature is displayed by color range across a map of the world.
