Bar Chart Panel Type

Bar Chart

A Bar chart is a plot chart that shows frequency of a single or a few different categories over time. This helps in directly comparing the values of different categories, which correspond to the length of the bar. This is particularly useful when you have discrete categorical data and you want to highlight differences.

Data Formats

Supported signals

• Logs
• Traces
• Metrics

This panel type supports any time series data. The time series data can be from logs, traces, or metrics.

Examples

The following graph shows the requests per second (req/s) for a service over a period of time in bar chart.

Configuration

Visualization

• Panel Time Preference — Override the global dashboard time range for this panel. Set to Global Time to use the dashboard's time picker, or choose a fixed time range.
• Stack Series — Toggle to combine multiple series into a single stacked bar. In stacked mode, each series is shown as a colored segment, making it easy to see the overall total and each series' contribution. Stacking is enabled by default.

Formatting & Units

• Y Axis Unit — The unit of the y-axis (for example, Milliseconds (ms), Bytes, Percent). The default is None.
• Decimal Precision — Number of decimal places to display. The default is 2 decimals.

Axes

• Soft Min / Soft Max — Adjust the y-axis scale for better visualization. When set, the y-axis range uses these values instead of auto-adjusting based on the data. Useful when you want to prevent small values from being magnified too much.
• Y Axis Scale — Choose between Linear and Logarithmic scale for the y-axis.

Legend

• Position — Set the legend position (Bottom or Right).
• Legend Colors — Customize colors for individual series in the legend.

Alerts

Link existing alert rules to this panel or create new alerts directly from the panel configuration.

Context Links

Add context links to enable click-through navigation from the panel to other dashboards, external URLs, or filtered views. See Interactivity for details.

Thresholds

Thresholds are used to draw a line on the y-axis to highlight the value. The thresholds are defined as a list of tuples. Each tuple contains the value and the color. The color is optional and if not provided, the default color will be used.
