# Trend **** This documentation topic is designed for Grafana workspaces that support **Grafana version 12.x**. For Grafana workspaces that support Grafana version 10.x, see [Working in Grafana version 10](using-grafana-v10.md). For Grafana workspaces that support Grafana version 9.x, see [Working in Grafana version 9](using-grafana-v9.md). For Grafana workspaces that support Grafana version 8.x, see [Working in Grafana version 8](using-grafana-v8.md). 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](v12-panels-time-series.md) with the following exceptions: + No annotations or time regions + No shared cursor (or 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.
