Heatmap - An overview

What is it for?

Ideal for visually representing relationships between values using color-coding, the heatmap template plots the magnitude of a phenomenon with the help of color in one or two dimensions. By being able to handle categorical and numerical data, as well as offering filtering and customizable popups, it a one-stop solution for visualizing relational data.

How to get started

1
The first step is to select a blueprint in the template chooser. You can choose between a heatmap with categorical data, one with numerical data and a heatmap with a built-in filter. Note that you can easily switch between them through settings even after you have made your selection.


2
As the heatmap is essentially a time-tested way to present relations using matrices between values in two dimensions, you need data for the X axis, the Y axis and for the Values that "bind" them together. You can upload them to the data sheet and bind the columns to the relevant column bindings.

3
If something does not look right, it is possible that you need to change the type of data for the X and/or the Y axis, as the heatmap can accommodate both numerical and categorical data.

4
Conversely, choose between a categorical and a numeric color palette according to the data that "binds" your axes together.

5
In case you need a filter, add the column containing the data you want to filter on in the Filter data binding.

It is also possible to customize the filter toggle through the Controls settings.
