Bar Gauge
A bar gauge displays the current value of a metric as a filled bar, showing where it sits within its defined range. It is ideal for real-time monitoring of one or more metrics, and quickly determining whether a metric is approaching or exceeding a threshold. Compared to circular gauges, bar gauges can display more metrics within the same panel space.

Title
You can set a main title and subtitle for the panel, displayed at the top, to describe the chart's subject matter.
Layout
The bar gauge supports two layout orientations:
- Horizontal: Bars extend in the horizontal direction, with labels on the left. Suitable for displaying multiple metrics.
- Vertical: Bars extend in the vertical direction, with labels at the bottom. Suitable for emphasizing the magnitude of a single metric.
Value Display
Controls how the numeric value is displayed above the bar. Three modes are supported:
- Value Color: The value color follows the color of the current threshold zone, visually reflecting the current state.
- Text Color: The value is always displayed in a fixed text color, independent of threshold changes.
- Hidden: No value is displayed; only the fill state of the bar is shown.
Name Display
Controls how the metric name is shown:
- Auto: The system automatically determines whether to show the metric name based on available space.
- Hidden: The metric name is always hidden.
Bar Size
- Auto: The system automatically calculates the size of each bar based on the panel dimensions and the number of metrics.
- Manual: Manually specify the width (horizontal layout) or height (vertical layout) of each bar in pixels.
Value Range
- Min Value: Sets the lower bound of the bar range. If not set, the minimum value from the data is used automatically.
- Max Value: Sets the upper bound of the bar range. If not set, the maximum value from the data is used automatically.
- Decimal Places: Controls the number of decimal places displayed in the value.
Thresholds
Thresholds divide the value range into color-coded zones, helping users quickly determine which state zone the current value falls into (e.g., Normal, Warning, Critical). Click + Add Threshold to add multiple thresholds.
Each threshold consists of:
- Value: The boundary value for the threshold.
- Color: The fill color of the bar when the value exceeds this threshold.
It is recommended to configure at least two thresholds. For example: set below 80% as green (Normal), 80%–95% as yellow (Warning), and above 95% as red (Critical), so that the bar color intuitively reflects the equipment operating status.
Notification Rules
Notification rules can be configured for the panel. When a metric value triggers a preset condition, the system will automatically send an alert notification. Refer to the Notification Rules documentation for details.
Roadmap
To continuously enhance your user experience, we will keep adding practical configurations in subsequent product updates, allowing you to enjoy richer and more user-friendly analysis features.
| Configuration | Description |
|---|---|
| Gradient Fill | Support enabling gradient fill effects on the bar for smoother visual transitions |
| Background Fill | Support filling the entire range area with a semi-transparent background to enhance the spatial feel |
| Value Unit | Support displaying the unit of measurement after the value for intuitive data reading |
| Color Scheme | Currently, each metric's color is determined by thresholds; future updates will provide default color schemes for scenarios without thresholds |
