Area Chart

An area chart is used to display data that depicts a time-series relationship. It involves plotting data points on x- and y-axes and connecting them with lines. Area charts are primarily used when the magnitude of the trend is to be communicated rather than individual data values. This chart is effective for emphasizing trends, often by filling the area under the lines with color or shading.

Area charts are preferred when you want to communicate the overall trend in your data rather than individual values. They are especially useful for representing multiple data series with part-to-whole relationships or cumulative data sets.

Creating an Area Chart

To create the Area chart

  • Create a New Dashboard Panel
  • Configure the Query and select the appropriate Data Source

(Refer to Dashboard Creation > Query)

Select Visualization

On the right side of the default screen, select Visualization as Time series to create an Area Chart panel.

Visualization Options 

Panel Options

There are multiple options to edit the properties of the panel. The first one is Panel Options. Enter a Name and Description for the Panel that you want to create. For instance, if you’re making an area chart to track CPU usage, name the panel “Area Chart” and describe it as “CPU Usage.”

The Description is available in the top left corner and can be viewed by hovering over the i button.

The next part of Panel Options is Panel Link where you can point a link to any other website or dashboard of your choice. Enter a title, and URL, and select the ‘Open in a new Tab’ option if you want to open the link in a new tab. Click Save.

The URL can be a link to another dashboard or for getting help or useful info. When you click on a panel, it opens the link either in the same tab or a new tab, depending on your choices. For example, if you want to compare a default dashboard, just click the link to open it.


The next section is the Tooltip which is used to show the details of a panel.

There are 3 options to configure the Tooltip:

  • Single: Show the tooltip at a single point.
  • All: Show the tooltip at all points.
  • Hidden: The tooltip is not shown at any point.

As you can see, there is a green-colored tip showing wherever you click on the graph.


The next option is the “Legend,” which essentially allows you to choose how you want the legend values to appear: at the bottom or on the right. The purpose of a legend is to provide a key or explanatory information for symbols, colors, or other elements used in a chart, map, diagram, or any visual representation

As for the Legend mode, you can display it in two ways:

  • List: The legends are displayed as a list.

  • Table: The legends are displayed as a table.

  • Hidden: The legends are not displayed.

Legend Values

You can select a number of values such as Last, First, Min, Max, Total, etc to show in the legend.

The values are the specific properties of the data.

The corresponding properties of the data will be displayed as a legend in the graph.

Graph Styles

Use this option to define how to display your time series data. You can use overrides to combine multiple styles in the same graph.

  • Lines
  • Bars
  • Points


Line interpolation

Choose how the graph connects data points:

  • Linear: Points are joined by straight lines.
  • Smooth: Curved lines for smoother transitions.
  • Step before: Steps between points, with points at the step’s end.
  • Step after: Steps between points, with points at the step’s start.

There are other options to configure such as:

  • Line width: The width of the line.
  • Fill opacity: The opacity of the filled region.
  • Gradient mode: Specify the gradient fill color.
  • Line style: Solid, dash or dots.
  • Connect null values: Choose how null values, which are gaps in the data, appear on the graph.
  • Show point: Show or hide point.
  • Point size: Size of the points.
  • Stack series: Stacking allows to display series on top of each other.


Bar Alignment

Set the position of the bar relative to a data point. In the examples below, Show points is set to Always which makes it easier to see the difference this setting makes. The points do not change; the bars change in relationship to the points.

  • Before  The bar is before the point, with the point at the trailing corner.
  • Center The bar encircles the point, with the point in the center (default).
  • After  The bar is after the point, with the point at the leading corner.

The secondary options for Bar Style Graph include:

  • Line width: The width of the line.
  • Fill opacity: The opacity of the filled region.
  • Gradient mode: Specify the gradient fill color.
  • Line style: Solid, dash, or dots.
  • Show point: Show or hide point.
  • Point size: Size of the points.
  • Stack series: Stacking allows to display series on top of each other.


As for the Points style, it only contains:

  • Point size: Size of the points.
  • Stack seriesStacking allows to display series on top of each other.


The next option is the Axis from where you can configure all the axis settings of your graph.

The further options that you can configure in your axis settings are:

  • Placement: Choose Y-axis placement-  Auto, Left, Right, and Hidden.
  • Label: Set a Y-axis text label. Different labels for multiple Y-axes can be set using override.
  • Width: Fix the axis width.
  • Soft Min: Adjust Y-axis limits with a Soft Min.
  • Soft Max: Adjust Y-axis limits with a Soft Max.
  • Show Grid Lines: Auto, On, Off.
  • Scale: Set the Y-axis values scale – Logarithmic or Linear.

Standard Options

The Standard Options are used to configure the other standard settings in the graph. It changes the way the graph appears.

The further options include:

  • Unit type: The type of Unit parameters.
  • Min: Minimum value to be considered.
  • Max: Maximum value to be considered.
  • Decimal: Total digits after the decimal point.
  • Display name: Series name to be displayed.
  • Color scheme: choose a color scheme for the graph.
  • No Value: What to show when there is no value.

Data Links

The Data Links option is similar to the Panel Link where you can link a URL and then open it in another tab. It is placed on the data instead of the Panel.

You can click on the data anywhere and the link option will appear.

It is used for an instant link that you want to appear anytime you click on the data.

Value Mappings

The Value Mappings option allows you to find a certain value and wherever the value lies, the display text is displayed. If there is a similar value in the data, it highlights in the form of the color selected.


The Thresholds option allows you to define and color-code value thresholds in three display modes:

  • Not filled
  • As lines
  • As filled regions and lines

Set color-specific thresholds to visualize performance levels more effectively.

For instance, for CPU usage, use green for 30, yellow for 40, and red for 50, enabling quick detection of threshold breaches and immediate action or error alerts.

Add Field Override

Use the Add field Override option to modify existing fields. Overrides enable changes to field settings, same as the field options available in a particular panel, with the flexibility to select the target fields.

To add a field override, click on the Add Field Override button.

Select the Field type

Select a field type,  based on the following properties:

  • Name: Set properties for a specific field with a name.
  • Matching Regex: Set properties for fields with name matching a regex.
  • Type: Set properties for a field of a specific type (number, string, boolean).
  • Query: Set properties from the field for a specific query.
  1. Select the Field.
  2. Select the override property.
  3. Configure the override property.

You can add multiple fields overrides by repeating the same.

You have now learned how to configure the Area Chart, change the panel settings, and more. You can save and edit the panel later too.


  1. Why would I use an area chart?

An area chart is a good way to demonstrate trends over time to the viewer, for example

showing the population over time. This chart is based on the line chart. The filled area

can give a greater sense of the trends in a particular dataset.

  1. Which chart type should I select to observe changes over time?

An area chart is helpful if you want to observe how a metric, such as population, changes over time.

  1. How can I change my current chart (area) to a line chart or bar chart without creating a new chart?

Go to the “Graphs Style” tab and change the chart type to a line or bar based on your needs.

  1. How do I change the color for the legends and set the selected color as a default color?

Go to Standard Options, choose the color scheme for your series, and save your visualization. Your area chart will be saved along with the chosen colors.

  1. How do I change the position of the legend?

Go to Axis settings and change the legend position to the right, left, top, or bottom.

  1. Why does my area chart show no result or not displayed?

The following things need to be checked.

    • Global time selector – Whether data is available for the duration selected in the global time.
    • Metric – Whether the selected metric field contains data in the underlying index.
    • Group By – Whether the selected bucketing field contains data in the underlying index.

  1. How can I sort my Group By field in ascending or descending order if it’s not a time series field?

Choose your Group By field in the Query tab and select “Terms”  and in the Order section, select Top or Bottom.
