No data visible in dashboard

Introduction

Has your asset recently sent data, but the dashboard widgets are not displaying any values? This may be related to your settings.

Check the aggregation type

When adding a widget to a dashboard, you can select an aggregation type for sensor data:

• MIN: the lowest value in the chosen time period.

• MAX: the highest value in the chosen time period.

• SUM: the sum of all values in the chosen time period.

• AVG: the average of the values in the chosen time period.

• COUNT: the number of values that have been sent in the chosen period.

• FIRST: the first value in the chosen period.

• LAST: the last value in the chosen period.

• DIFF: the difference between the first and last value in the chosen period.

• LASTKNOWN: the last value outside of the chosen time period.

Tip!

Chosen period: this is the time span for which you want to see data. You can always adjust this period at the top of your dashboard.

Solution

Open and edit the dashboard.

Open the widget settings.

Choose LASTKNOWN as the aggregation type.
Save the changes.
