An active Ubidots account
1. Create a Ring Gauge Widget
Step 1. While in a dashboard, click "+" button located at the upper right corner of the screen.
Step 2. Once in the widgets' drawer, look for and select the Ring Gauge option.
Step 3: Add up to 4 variables to be displayed and configure the following parameters:
Select the aggregation Method to compute maximum, minimum, count, average or sum based on each variable's data. Alternatively, select "last value" to display the variable's last value.
Choose a time span for each variable. Option "Set by dashboard" corresponds to the Dashboard's general date time picker span.
Select the range value to set the limits of the arc for the variable within the widget. Negative values are accepted.
Select the variable color. There are three available options:
Set by widget: A fixed, predefined color that you choose using a color picker or manually entering the hex or RGBA value.
Variable's default: The color assigned to the variable directly in its settings.
Define a color logic that works based on the variable's value.
NOTE: The variables are placed clockwise around the Ring starting at the 12 o'clock position. Also, the positive direction for values is clockwise.
Step 4: In the appearance tab, you can:
Name your widget.
Configure the decimal places.
Define a date format.
Choose a text font.
Add a background image.
Define a background color.
Further customize the widget's appearance using the "custom style" editor.
