Display data in the form of a matrix in which values are represented as colors.
Data Structure #
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:
Heat Map Configuration #
The Heat Map Visualization configuration is broken out into three steps:
Identifies the name and some baseline properties of the visualization.
Determines colors for the Heat Map.
Previews the end result based on the choices you made.
Step 1: Configure #
Configuring a Heat Map involves mapping attribute names to the appropriate axis of the Visualization.
Name of the Visualization.
X-Axis Column #
Attribute used for the X-Axis of the Heat Map (horizontal axis).
Show X-Axis Labels #
Determines whether to show labels for the X-Axis (horizontal axis).
|Yes||X-Axis labels will be shown at the top of the Visualization|
|No||X-Axis labels are hidden.|
Y-Axis Column #
Attribute used for the Y-Axis of the Heat Map (vertical axis).
Show Y-Axis Labels #
Determines whether to show labels for the Y-Axis (vertical axis).
|Yes||Y-Axis labels will be shown on the left hand side of the Visualization|
|No||Y-Axis labels are hidden.|
Y-Axis Label Width #
Width allotted for the Y-axis label.
Step 2: Renderer #
The Heat Map’s renderer conveys the concept of heat. The larger the value, the warmer the temperature.
Derived Thresholds #
Determines how “heat” is calculated.
Values Column #
Select an attribute to determine “heat” (intensity) of the cells. It must be an attribute with numeric values.
Color Palette #
This property will appear when Derived Thresholds is set to false. The color palette will determine the granularity of the Heat Map.
See Color Palettes for more information.
Corner Radius #
Determines the corner radius of each cell in the grid. The values are specified as a percentage.
Step 3: Preview #
Provides a preview of the resulting Visualization.
