Area and line charts

Use line and area charts to track value trends over time. You can also use a line or area chart x-axis to represent a field value other than time.

A line chart with two differently colored and styled lines.
An area chart with multiple differently colored fields -- each stacked against each other.

Data formatting

Line charts can represent one or more data series. Area charts depict multiple data series.

If a search generates multiple series, each line or area in the chart appears in a different color.

To make sure that a search generates data series correctly, check the Statistics tab in Search & Reporting. The Statistics table should have at least two columns for a single series, and three or more columns for multiple series.

Statistics table order and chart axes

Line and area charts receive x-axis values from the first column in the statistics table. The remaining table columns become y-axis values.

For example, any search using the timechart reporting command generates a table where _time is the first column. A line or area chart generated with this search has a _time x-axis.

Search results not structured as a table with valid x-axis or y-axis values cannot generate line or area charts. For example, using the eval or fields commands might change the search result structure.

Generate a line or area chart

  1. Select the line or area chart using the visual editor by clicking the Add Chart button ( The Add Chart button in the editing toolbar. ) in the editing toolbar and either browsing through the available charts, or by using the search option.
  2. Select the chart on your dashboard so that it's highlighted with the blue editing outline.
  3. Set up a new data source by adding a search to the Search with SPL window if you are selecting a chart.
  4. To select an existing data source, close the Configuration panel and reopen it. In the Data Configurations section, click +Setup Primary Data Source and click + Create Ad hoc Search to create a new search from this window. You can also choose a new ID that describes the search better than the default.

Configuration Panel options for line and area charts

You can use the Configuration panel to configure the following line chart components.

Title

Give your visualization a name. The title name is also helpful when searching for individual visualizations in the dashboard definitions and is not the same as the automatically assigned unique ID.

Description

Give your visualization a description to explain what the user is viewing.

Data Configurations

Choose an existing search or create a new one.

Position & Size
You can use your mouse or the Position & Size section of the Configuration panel to change the size or location of the visualization for pixel-perfect sizing and placement.

General

    Use Null Values to do one of the following:
  • Show markers for any disconnected data points a gap.
  • Connect null data points to zero data points.
  • Connect them to the next positive data point.
    Use the following Stack Mode (area charts only) options:
    Stack option Column or bar appearance Use case
    Unstacked Areas for different series share the same space on the chart. An unstacked chart is useful for a lower number of series. As the number of series increases, the chart can become more difficult to understand.
    Stacked Each series area is shown separately. Use a stacked area chart to highlight the relative volume, frequency, or importance of a series. See the stacked chart example LINK HERE in the Line and area chart introduction.
    Stacked 100% The chart shows distribution percentage for each series over the whole data set. Use stacked 100% to focus on data distributions.

    Use Show Data Values to show no data values, all data values, or only the minimum and maximum data values.

Axes

  • Use X Axis title to name your x-axis.
  • Use Y Axis title to name your y-axis.

Legend

  • Use Position to choose the position of the legend.
  • Use Truncation to choose how legend labels are truncated when they overflow the layout boundaries by choosing where to place ellipses (...)

Drilldown
Drilldown for a line or area chart lets users click on a part of the chart to open an internal or external URL.

Code
Select your visualization or its search to view and edit the source code in real-time. You can also change the Visualization ID to a more readable ID to help identify this visualization in the source code.

Source options for line and area charts

While you can set some of these options using the visual editor, additional options exist that can only be set in the source editor for splunk.line and splunk.area. Add these options to the options field of the visualization stanza. For example, the following shows the addition of solid or dashed line styles, as well as using hex code colors for specific fields:

"viz_25NNIqLF": {
    "type": "splunk.line",
    "dataSources": {
       "primary": "ds_search2"
    },
    "options": {
       "seriesColorsByField": {
          "This Year": "#35B9A0",
          "Last Year": "#14846C"
       },
       "lineDashStylesByField": {
          "This Year": "solid",
          "Last Year": "shortDash"
       }
    },
}
