When you add a graph widget or single value widget to an ITE dashboard, you can use math functions to add calculations.

## Sensor

Adding a sensor shows the sensor values for the duration you select in a graph widget, or the latest sensor value in a single value widget.

## Static value

Select static value to show a single value in a widget, or a horizontal line in a graph widget. You can also use a static value in a calculation as a constant.

## Math functions

### Max** **

Use the max function to show the largest value from a set of sensor data.

*Example 1: Create a series for a graph widget and add a max function to multiple sensors. The resulting graph shows the largest sensor value for a time interval. A time interval is defined by the smallest pull cycle for the selected sensors. *

*Example 2: Create a single value widget and add a max function to multiple sensors. The resulting value is the latest max of the sensor data.*

### Min

Use the min function to show the smallest value from a set of sensor data.

*Example 1: Create a series for a graph widget and add a min function to multiple sensors. The resulting graph shows the smallest sensor value for a time interval. A time interval is defined by the smallest pull cycle for the selected sensors. *

*Example 2: Create a single value widget and add a min function to multiple sensors. The resulting value is the latest min of the sensor data.*

### Average

Use the average function to show the arithmetic mean of a set of sensor data.

*Example 1: Create a series for a graph widget and add an average function to multiple sensors. The resulting graph shows the mean sensor value for a time interval. A time interval is defined by the smallest pull cycle for the selected sensors. *

*Example 2: Create a single value widget and add a an average function to multiple sensors. The resulting value is the latest mean of the sensor data.*

### Sum** **

Use the sum function to add up all the values for each point in time.

*Example 1: Create a series for a graph widget and add a sum function to multiple sensors. The resulting graph shows the sum of all sensor values for a time interval. A time interval is defined by the smallest pull cycle for the selected sensors. *

*Example 2: Create a single value widget and add a sum function to multiple sensors. The resulting value is the sum of the latest sensor data.*
