Modify a Chart

You can customize a chart on a dashboard panel in a variety of ways. You can even change the chart type to analyze the data in another format. This section shows you how to customize a chart or change the chart type entirely. 

Customize a chart

You can customize each chart by modifying the available settings. The settings you can change vary according to the chart type. This page shows you how to edit a panel and customize General, Display, Display Overrides, Axes, Legend, and JSON chart settings.

Group by setting

Honeycomb charts and categorical column and bar charts from metrics queries have a Group By setting. Use the Group By setting to group the data shown in your chart by a dimension already displayed in the output data.

Override dashboard displays

The ability to override dashboard displays allows you to create panel visualizations that make charts easier to assess and form conclusions. You can override selected dashboard displays to create a visual story that highlights what is most important to monitor.

For example, you may want to set a specific time-series to red to signify that it represents errors, or overlay two different metrics with different axis ranges so it's easy to correlate across them. You may also want to rename the legend and tooltip values of a chart for readability and ease of use.

To override select dashboard displays, do the following:

  1. Click the Display Overrides icon in the far right menu bar.

MC_Display_Overrides_icon.png

  1. Enter a Query or series name you want to override. This is the letter of the row the query is assigned to, for example #A and #B.

    The following image shows a metrics and logs query charted together. In the Display Overrides menu the Logs query is referenced as #B to assign an alias and red color.

  2. Enter an Alias, as necessary. Metrics monitors allow you to specify output metadata as a variable wrapped in double curly brackets, {{ }}. For example, if my output metrics has environment, I can specify it in my alias as {{ metric }} on {{ deployment }}.

  3. Select a Property from the drop-down list. You can add as many properties and needed.
  4. Optionally, add another override by selecting Add New Override and completing steps 2 - 4.
  5. To save your customized settings and return to the dashboard, click Update Dashboard in the upper right corner of the window.

    • Label Font Size. Size of the label font

    • Gridline. Color for the gridline

The Left Y-Axis is the secondary axis created from your query. It is displayed by default.

Enter or modify the following options, as necessary:

  • Scale. Options vary according to chart type

  • Decimals. Sets the precision of units displayed. Select the number of decimals to show with a unit, up to 9.

The Right Y-Axis has the same options as the Left Y-Axis. If you have created a Display Override and set the YAxisType property to Right Y-Axis for a query you'll have the option to modify the Right Y-Axis here.
