Display data in the form of a matrix in which values are represented as colors.
The Heat Map Visualization requires data to be structured as a matrix. It expects X-Axis and Y-Axis values to appear as Attributes within the data. See example below:
The Heat Map Visualization configuration is broken out into three steps:
Configuring a Heat Map involves mapping attribute names to the appropriate axis of the Visualization.
Name of the Visualization.
Attribute used for the X-Axis of the Heat Map (horizontal axis).
Determines whether to show labels for the X-Axis (horizontal axis).
Attribute used for the Y-Axis of the Heat Map (vertical axis).
Determines whether to show labels for the Y-Axis (vertical axis).
Width allotted for the Y-axis label.
The Heat Map’s renderer conveys the concept of heat. The larger the value, the warmer the temperature.
Determines how “heat” is calculated.
Select an attribute to determine “heat” (intensity) of the cells. It must be an attribute with numeric values.
This property will appear when Derived Thresholds is set to false. The color palette will determine the granularity of the Heat Map. For example, if a color palette has 10 colors, then the Heat Map will calculate 10 threshold values. All 10 colors from the color palette will appear in the Heat Map’s legend.
See Color Palettes for more information.
Determines the corner radius of each cell in the grid. The values are specified as a percentage.
