Semi Gauge Chart
A Semi-gauge chart displays a single metric's value against a target, dynamically changing colors to show if the data is within, approaching, or exceeding a predefined range.
A Semi-Gauge Chart is a visualization that uses a semi-circle dial with a needle to indicate a target value against a defined range. The gauge dynamically changes color ranges to signal whether monitored data is within limits, approaching thresholds, or exceeding them. This chart is particularly effective in dashboards, real-time monitoring systems, and executive reports, where quick status interpretation is essential.
When to Use a Semi-Gauge Chart
Use a Semi-Gauge Chart when you want to:
Track Key Performance Indicators (KPIs) against predefined ranges.
Monitor progress indicators and instantly flag performance shortfalls.
Represent quantity or percentage metrics within a limited scale.
Highlight alerts when actual values exceed thresholds.
Examples:
Monitoring student or class performance in an examination.
Displaying real-time server load utilization.
Tracking project progress against a completion target.
Chart Properties
General Settings
Show Range – Display range bands on the semi-gauge.
Minimum Value – Define the lowest scale value (must be less than Maximum).
Maximum Value – Define the highest scale value (must be greater than Minimum).
Target – Enable/disable the target indicator.
Target Value – Set the numeric target to display on the gauge.
Field as Target – Use a measure field instead of a static value as the target.
Aggregation – Choose aggregation type (Sum, Avg, etc.).
Measure – Select the measure field.
Target Color – Assign a color to the target marker.
Speedometer Width – Adjust the width of the gauge arc.
Needle Width – Adjust the thickness of the needle pointer.
Center Color – Set color for the gauge’s center hub.
Show Ticks – Display tick marks on the gauge.
Ticks Color – Choose tick mark color.
Pointer Color – Set needle/pointer color.
Font Color – Define font color for the numeric value shown.
Marker Font Color – Define font color for range start and end markers.
Show Title – Display chart title.
Title – Enter the chart’s title text.
Title Font Color – Customize title font color.
Exclude Global Filter – Prevent global filters from affecting this chart.
View Filter
Filter – Apply filter conditions to restrict which measure/dimension data is displayed.
Range
Show Alert – Enable color-coded ranges (% based).
Add – Insert a new range with custom color coding.
Value Color – Assign color for values in the range.
Base Color – Assign base background color.
Format
Precision – Set decimal precision (up to 5).
Format Type – Select format: None, Auto, Percent, Thousand, Lacs, Crore, Million, Billion, Trillion, Quadrillion.
Currency Type – Display values with symbols (Rupees, Euro, Pound, USD, Yen, Cent).
Notes & Constraints
The target value must fall within the min–max range of the gauge.
Semi-Gauge supports only one measure value.
If a Dimension is selected, it is automatically converted to a Measure.
Base color appears when the set Maximum Value exceeds the dataset’s maximum measure value.
Best Practices
Use contrasting range colors (e.g., green, yellow, red) to make status zones clear.
Keep ranges limited (e.g., 3–5) for readability.
Apply alerts sparingly to emphasize critical KPIs only.
Ensure targets are realistic and within the defined range to avoid misleading visuals.
