Heatmap

A heatmap is a graphical representation of data where a metric is represented at the intersection of 2 attribute values. VitaraCharts’ custom table heatmap allows you to place multiple attributes on the columns (axis and y-axis) and at a glance display the variations in the measures. A sample table heatmap is presented below.

Inputs

Metrics: The minimum 1 metric is required.

Attributes: A minimum of 2 attributes are required. The first attribute A1 is used for the x-axis and the second attribute A2 is used for the Y axis.

Thresholds

By default Heatmap creates a threshold (Gradient threshold) and plot colors based on this threshold. Below is the screenshot of threshold editor of heatmap. Threshold editor shows the default threshold applied on the chart. We can edit this threshold or delete this threshold and create a new one by clicking on ‘Add’ button.
