Gauge

A Gauge widget is a type of circular-arc graph that displays the value of a measured parameter inside the arc. A needle points to the arc to show the value's location on the circle. Gauge widgets can be used in various contexts to provide a quick and easy way to understand the status or level of a measured value.

The Gauge widget is available in Device Types, Devices, and Global Dashboards.

In the Widget options modal, enter a name as the label for your widget in the Name text box, and select the appropriate data field from the Data field drop-down list.

By default, the first row of the range entity is populated with 'from' (lower bound) and 'to' (upper bound) values that you have configured in the Device Types -> Data fields section in the Uplink tab, allowing you to apply a single color to the whole gauge.

To allow users to visualize different ranges of a measured value, such as soil moisture levels, a gauge can be divided into multiple ranges.

Click on the + button. The 'To' text box of the first row enables you to enter the 'to' value of the first range. As you enter the value in the 'To' text box of the first row, it will automatically be added to the 'From' text box of the second row, ensuring that the two ranges do not overlap. To add more ranges to the gauge, simply click the + button to add a new row. By default, each new range will start from the 'To' value of the previous range, ensuring that the ranges do not overlap.

Select a color from the color picker in each row to assign a unique color to that range.

By assigning specific colors to each range, users can quickly determine the status of the measured value and take appropriate action as needed.

Click on the Gradient checkbox if you want to enable a smooth transition of colors between each range.

To add a color to the background of the widget, click on the Background color box and choose a color from the color picker.

Click on the Save button.

The resulting Gauge widget looks something like this:
