The DigitalMeter is a graphical component designed to display numerical values in a clear and customizable digital format within Displays/Draw. It supports multiple meters, which can be populated through DataTables or configured manually. This makes it suitable for visualizing values such as power consumption, temperature, order status, and other real-time or static data points.

Field | Description |
DataTable | Associates a DataTable with the meter. The table must include columns named Title, Value, MinValue and MaxValue. |
Number of Bars | Defines the number of bars of the meter that will be present in each one. |
Start Color | Defines the start color of the meter, indicating low values. |
End Color | Defines the final color of the meter, indicating high values. |
Runtime Execution
The DigitalMeter supports real-time data visualization through a linked DataTable.
The meter updates dynamically based on the connected dataset. It retrieves a list of meters, one per row, using the data of Title, Value, MinValue and MaxValue columns to construct each meter, ensuring accurate real-time display.
DataTable Fail-Safe
If the associated DataTable does not contain Title or Value columns, the component will not render data from the table. Instead, it loads default meters as a fallback, ensuring the chart continues to display data even if the linked DataTable is unavailable or misconfigured. If the MinValue or MaxValue columns are not defined in the table, default values of 0 and 100 are used, respectively.
