Axis in React Heatmap chart component

14 Mar 202324 minutes to read

Heat map consists of two axes namely, X-axis and Y-axis that displays the row headers and column headers to plot the data points respectively. You can define the type, format, and other customizing options for both axes in the heat map.

Types

There are three different axis types available in the heat map, which defines the data type of the axis labels. You can define the axis type by using the valueType property in the heat map.

Category axis

Category axis type is used to represent the string values in axis labels.

Inversed axis

Heat map supports inversing the axis origin for both axes, where the axis labels are placed in an inversed manner. You can enable axis inversing by enabling the isInversed property.

Opposed axis

In heat map, you can place the axis label in an opposite position of its default axis label position by using the opposedPosition property.

Label formatting

Heat map supports formatting the axis labels by using the labelFormat property. Using this property, you can customize the axis label by global string format (‘P’, ‘C’, etc) or customized format like ‘{value}°C’.

Axis intervals

In heat map, you can define an interval between the axis labels using the interval property. In date-time axis, you can change the interval mode by using the intervalType property. The date-time axis supports the following interval types:

  • Years
  • Months
  • Days
  • Hours
  • Minutes

Axis label increment

Axis label increment in the heat map is used to display the axis labels with regular interval values in numeric and date-time axes. The labels will be displayed with tick gaps when you set the label interval. But, to achieve the same behavior without tick gaps, use the label increment. You can set the axis label increment using the increment property and the default value of this property is 1.

Limiting labels in date-time axis

You can display the axis labels at specific time intervals along with the date-time axis using the showLabelOn property. This property supports the following types:

  • None: Displays the axis labels based on the intervalType and interval property of the axis. This type is default value of the showLabelOn property.
  • Years: Displays the axis labels on every year between given date-time range.
  • Months: Displays the axis labels on every month between given date-time range.
  • Days: Displays the axis labels on every day between given date-time range.
  • Minutes: Displays the axis labels on every minute between given date-time range.
