Line Charts

Create a customized line chart and visualize logs or metrics in Custom Dashboards.

Create a Line Chart

STEP 1. In a custom dashboard, drag and drop the Line Chart widget from the left-hand sidebar to get started.

STEP 2. Set the definitions for your Line Chart in the right-hand sidebar.

Name & Description. Create a name and description for your line chart.
Load data from. Select whether to load data from Frequent Search or Monitoring.

Source. Select a data type.
- If the data type chosen is metrics, specify the metric or desired PromQL in the Query field. Use free text to search for a metric of your choice. As you do so, all relevant metrics will appear. Hover over any metric to view its system-generated metadata labels. Hover over a label to see its values.
- If the data type chosen is logs or spans, you will be directed to select the following fields:
  - Aggregation: Aggregate by Count, Count Distinct, Sum, Min, Max, and/or Average
  - Group By: Select any field from the dropdown menu
+ ADD FILTER. [Optional] Add a widget filter.
- As opposed to the dashboard filter in the left-hand sidebar which affects the entire dashboard, this filter only affects the widget.
- The widget and dashboard filters operate in parallel to one another and intersect. If they negate one another, dashboard filters override widget filters.
Advanced: Select from the following advanced options.
- Scale. Select whether you want the scale of the line chart to be Logarithmic or Linear. The default setting is linear, however if you have large differences between the different values, it can be helpful to show the logarithmic scale instead. For example, if the majority of your values are under 1k and one value is 10k, using the logarithmic scale will show you an easier to read line chart than the linear scale.
- Series Per Query.
- Series Name. Create a series name
- Unit. Select the unit type to use in your line chart.
- Stacked Line. Stacking allows you to layer time series on top of each other, offering insights into the overall trend over time and the individual contribution of each series to that trend.
  In a stacked line chart, instead of having separate lines for each series, the series values are stacked on top of one another at each time point. This allows viewers to see the overall trend over time and the contribution of each series to that trend.
  Toggle to activate, then choose from one of the following:
  - Absolute: Stacks series on top of each other.
  - Relative: Stacks by percentage where all series add up to 100%.
- Tooltip. Select whether to see all time series when hovering over them, or to see only the single time series you hover over.
- Legend Values. Customize values to be displayed in your legend: Min, Max, Sum, Avg, Last.
- Color Scheme. Select the color scheme for your chart. Note that when Legend Colors By Group is selected, color scheme is disabled.

STEP 3. In the bottom Query bar, add a Lucene or PromQL query to query specific information.
