Plot bands in a Solid Gauge chart are used to visually
segment the gauge's scale into color-coded ranges. These helps highlight zones
such as 'Low', 'Medium', 'High', or indicate threshold levels. Plot bands are
static. Plot band configuration is done using the Highlight configuration.
Purpose of Plot Band:
- Visually divide the gauge into value-based ranges.
- Highlight critical thresholds or safe/alert zones.
Configure Plot Band:
Plot Band formatter is available in Chart
formatters of Solid Guage chart. Follow below steps to configure Plot Band on Solid
Guage chart:
1. Chart
formatters >> Turn on the Toggle button of Plot Band.
2. Turning ON of Plot Band sets the Highlight
configuration to Turn OFF, if tuned ON previously.

On toggle button in Highlight -Apply formatter
4. Highlight
modal is displayed as below, showing the options to Add Level

5. Add
the levels to show the different ranges on the chart as below. The minimum and maximum
value displayed on the chart are 0 and 65.04 Thousand so add the levels accordingly.
Click Apply Button.

6. The
Plot Bands are set as data ranges on the solid guage chart, visualizing chart
as below.

The levels are set on the chart as below:
0 to 20000
|
Red
|
> 20000 to 40000
|
Yellow
|
> 40000 to 60000

> 60000 to 100000
|
Violet

Reflected Changes on the Chart:
The value 32.52 Thousand lies between 20000 to 40000 levels which refer
to Yellow color hence the chart data color is displayed Yellow. Data label
showing the label with Yellow color.
Guage axis labels are available showing the data ranges – 20 Thousand,
40 Thousand, 60 Thousand.
Notes:
|
· When the chart is fully configured—either
through the Configuration panel or via Formatters > Gauge Axis
options—the highlight condition still evaluates the value configuration
as the left-hand side (LHS) for comparison against the specified operator
and operand value.
· Conditions defined in the Highlight modal
are evaluated dynamically based on real-time data. The chart applies the
corresponding visual changes using the filtered data available at that
specific moment.
· A Solid Gauge chart can be
configured using either Highlight or Plot Band settings—not
both simultaneously.
- When using Plot
Band, you must define level thresholds.
- When using Highlight,
you need to configure conditional rules.
· When Plot Band is used, it evaluates
the data value against the defined ranges and applies the corresponding color
to the chart segment where the value falls.
