Visualize relative data with bar charts

To add a bar chart panel to a standard dashboard:

1. Add a panel to a dashboard.
2. In the Add Panel interface, click the Type dropdown and select Bar Chart.
3. Add a query to the panel.
4. Click the Add button to add the panel to the dashboard and close the Add Panel interface.
5. Optional: On the dashboard, click Save to save the new panel to the dashboard.

You can configure a bar chart by modifying its Settings.

Any changes you make in the panel's Settings tab are immediately reflected in the Preview pane, but take effect only when you click Apply in the Edit panel interface and then Save the dashboard.

To modify a bar chart's settings using its Settings tab:

1. Edit the bar chart panel.
2. In the Edit panel interface, click the Settings tab.

The tab contains these settings under a section labeled Misc:

• Abbreviate: Toggles whether to abbreviate units on the Y axis. For example, if enabled, Observability Platform renders a value of 100000000 as 100M. You can toggle this setting only if you set the Unit to Decimal or Bytes. Time units are always abbreviated and Percent values don't require it. Defaults to true.
• Unit: Defines the unit used to render the Y axis. This has the most significant effect when you enable Abbreviate. Defaults to Decimal.

  • Decimal: Base 10 values. Observability Platform renders a value of 1000000 as 1M.

  • Bytes: As decimal multiple-byte units. Observability Platform renders a value of 1000000 as 1MB.

  • Time: Determines the unit of time that Observability Platform uses to interpret a numeric value. The unit you select isn't necessarily the unit Observability Platform displays.

    For example, if you select Nanoseconds, Observability Platform interprets a numeric value of 120 as 120 nanoseconds and renders it as 120ns. If you select Days, Observability Platform interprets the same value as 120 days and renders it as 4 months.

    Supported time units are Nanoseconds, Microseconds, Milliseconds, Seconds, Minutes, Hours, Days, Weeks, Months, and Years.

  • Percent: Interprets the value as a percentile, representing 0% to 100% on a range of either 0.0 to 1.0 (Percent (0.0-1.0)) or 0 and 100 (Percent (0-100)).

    For example, Observability Platform renders a value of 1.0 in Percent (0.0-1.0) as 100%, and in Percent (0-100) as 1%.

• Decimals: Defines how many decimal places Observability Platform renders for
• values. Default renders decimal places only if necessary and rounds to the nearest value. Numeric values from 0 to 4 render the corresponding number of decimal places.
• Calculation: Defines which data point or calculation to use as the bar's value, such as its average, minimum, maximum, or total values. Defaults to the last numeric value in a series (Last *).
  • First: The series' first value.
  • Last: The series' last value.
  • First *: The series' first numeric value.
  • Last *: The series' last numeric value.
  • Avg: The series' mean value, excluding null values.
  • Total: The sum of all values in the series.
  • Min: The series' minimum value.
  • Max: The series' maximum value.
• Sort: Determines how the bar chart sorts the rendered bars.
  • Default sorts the bars in their original data order.
  • Ascending sorts the bars from the lowest value at the top to the highest value at the bottom, and Descending sorts in the opposite direction.
• Mode: Determines whether the panel depicts a bar's numeric value as its literal Value or as a Percentage of the sum of all bars in the chart.
