### Creating a custom trend graph When creating a custom trend graph, you can select up to 16 points. If you select more than 4 points or points with different units, the WebCTRL® application splits the data into subgraphs. Each subgraph can show a maximum of 4 points with similar units. NOTES You must enable trending for points that you want to include in the custom trend graph. See To collect trend data for a point. You can display icons and hover text on the Geographic tree that show where custom trend graphs were created. See Tree icons and hover text.
