Trend

Trend visualizations should be used for datasets that have a sequential, numeric X that is not time. Some examples are function graphs, rpm/torque curves, supply/demand relationships, and elevation or heart rate plots along a race course (with x as distance or duration from start).

Trend visualizations support all visual styles and options available in the time series visualization with these exceptions:

No annotations or time regions
No shared cursor/crosshair
No multi-timezone x axis
No ability to change the dashboard time range via drag-selection

X Field selection

Use this option to select a field that contains increasing numeric values.

For example, you could represent engine power and torque versus speed where speed is plotted on the x axis and power and torque are plotted on the y axes.

Tooltip options control the information overlay that appears when you hover over data points in the visualization.

When you hover your cursor over the visualization, Grafana can display tooltips. Choose how tooltips behave.

Single - The hover tooltip shows only a single series, the one that you are hovering over on the visualization.
All - The hover tooltip shows all series in the visualization. Grafana highlights the series that you are hovering over in bold in the series list in the tooltip.
Hidden - Do not display the tooltip when you interact with the visualization.

Use an override to hide individual series from the tooltip.

Values sort order

When you set the Tooltip mode to All, the Values sort order option is displayed. This option controls the order in which values are listed in a tooltip. Choose from the following:

None - Grafana automatically sorts the values displayed in a tooltip.
Ascending - Values in the tooltip are listed from smallest to largest.
Descending - Values in the tooltip are listed from largest to smallest.

Hover proximity

Set the hover proximity (in pixels) to control how close the cursor must be to a data point to trigger the tooltip to display.

Max height

Set the maximum height of the tooltip box. The default is 600 pixels.

Value mappings

Value mapping is a technique you can use to change how data appears in a visualization.

For each value mapping, set the following options:

Condition - Choose what’s mapped to the display text and (optionally) color:
- Value - Specific values
- Range - Numerical ranges
- Regex - Regular expressions
- Special - Special values like Null, NaN (not a number), or boolean values like true and false
